2026 Fantasy Outlook
Semien's walk up song should have been Bob Seger's, "Like a Rock," because from 2015 to 2024, that is exactly what he was. He had an IL stint in 2017 but otherwise played in nearly every game possible for Oakland and Texas. That all came to a crashing end in 2025, as his worst statistical season on record finally came to a merciful end in August with a foot injury. Semien has played more games than any other active second baseman in baseball since 2015, and we know the position is not a forgiving one to older players. Semien enters his age-35 season in a new league and city after getting dealt to the Mets for Brandon Nimmo this offseason. He still has the foot speed, but the quality of his contact continues to decline, thus costing him one of those coveted higher spots in the lineup. He was a four-category contributor last season but nowhere near his previous levels. We only have to look to George Springer's 2025 renaissance to be reminded of how dangerous it can be to write off aging players so quickly. We are not recommending taking Semien for his previous volume or stature, but he's a likely everyday player with the upside to log the sixth 20/10 campaign of his career. Read Past Outlooks

May 6, 2026
Semien went 4-for-5 with a two-run home run, a double and three total runs scored in Wednesday's 10-5 win over the Rockies.
Analysis
Semien's four hits Wednesday matched the total from his previous seven games combined. The homer was his first since April 3 in San Francisco, and this was the first time he'd logged an extra-base hit since April 23 against the Twins. Semien is now batting .231 with a .602 OPS, two homers, 13 RBI, 11 runs scored, six doubles and four stolen bases over 36 contests. He's getting steady playing time but often hitting in the bottom half of the order due to his struggles at the plate early in the year -- he's hit above the No. 5 spot just once all season.

Like many other Rangers hitters, Semien struggled last season. The difference between Semien and most of his teammates is Semien's game is subject to more variance, and his underlying metrics were nearly identical to his recent levels, he simply didn't enjoy the same outcomes. Barrel rate, hard-hit rate and strikeout rate were typical. The only small change was a small drop in launch angle, generating fewer fly balls, resulting in Semien's fewest homers in a full season since 2018. He also failed to steal double-digit bases for the first time ever in a full season, but running often wanes in an off year. After missing just one game the prior three seasons, Semien was out for a whopping three. Semien is now 34 years old, so expecting a seventh consecutive full season with over 700 plate appearances is aggressive. He's still one of the best at a weaker position, but Semien can't get the same plaudits for durability and reliability as he could previously.
Semien needed a strong final four months to rebound from a slow start in his first season with the Rangers. He was much steadier in his second year and easily better overall with an .826 OPS in 2023 which was nearly 100 points higher than his 2022 mark. Semien's Statcast page was underwhelming as it always tends to be, but he's mastered the art of pulling flyballs down the line and just over the wall to the point that it's impossible to doubt that he simply has that skill. He also cut his strikeout rate in 2023 to 14.6 percent, allowing him to hit for a solid .276 average even with all the weakly- to moderately-struck flyballs mixed in. Finally, Semien continues to be the modern day Iron Man, leading the league in plate appearances for the third straight season. He's about as safe as an early-round pick gets.
For the second straight season, Semien led MLB with 724 plate appearances. His first nine games with the Rangers were disastrous with a .369 OPS. However, Semien recovered to post a .756 OPS the rest of the way. His 107 wRC+ was the third highest of his career, but that does not capture his 25 steals, by far his season high. Semien's Statcast page doesn't portend power, but he's quietly a fly-ball hitter with an uncanny ability to cluster them down the line where most fences are within reach. A career .263 BABIP reflects his fly-ball nature, but a strikeout rate around 20 percent props up Semien's average enough so his power/speed combo plays in any format. It would be more comforting if Semien's success was greater supported by a higher exit velocity or hard-hit rate, but Semien's track record of getting the job done lands him among the top fantasy second basemen, buoyed by excellent durability.
Now a two-time American League MVP finalist, Semien put together a career year between Dunedin, Buffalo and ultimately Toronto. He bet on himself on a one-year, $18 million deal with the Blue Jays last offseason, and turned that into seven years and $175 million with the Rangers. It didn't hurt that he was mostly batting first or second for the No. 3 offense in the AL, surrounded by some of the best hitters in the circuit. He feasted on fastballs, smashing 35 of his 45 homers off the heater while holding his own against offspeed pitches. He stole 15 bases in 16 attempts. Semien mostly struggled against breaking balls and his Statcast xBA ended up more than 20 points below his actual mark. Keep in mind we don't have enough data to know how Globe Life Field plays for offense, and Semien is already on the wrong side of 30, but as a rare triple-threat of power, speed and multi-position eligibility (2B, SS), Semien is an alluring option in the third round for 2022.
Coming off a monster 2019 season in which he cranked 33 homers, Semien fell back down to Earth in 2020, slashing .223/.305/.374 with seven long balls, 23 RBI and four stolen bases in 53 contests. While his power numbers were down considerably (not unexpectedly) during the shortened season, his .223 batting average was far more concerning, as it was his lowest mark since the 2014 campaign. It was also disappointing to see his K% rise to 21.2% after improving to 13.7% in 2019 during arguably the most successful season of his career at the dish. While there were several concerning stats to point out at the dish a season ago, he turned just 30 in September and could benefit from a move to a robust Toronto lineup. Semien will move to second base after signing a one-year, $18 million deal with the Blue Jays. With eligibility at shortstop, he'll provide someone who can hit for average, put on a display of power or flash his speed on any given day.
Semien enjoyed a monster year in 2019 for the resurgent Athletics. He has always strived to play every day, and he's done that the past two years with consecutive seasons of 700-plus plate appearances. Yes, the run production was a noticeable difference for him last year, but he changed his approach at the plate and greatly reduced his strikeout rate from the low 20s to 14% in just two seasons. Semien pushed his average exit velocity up by two miles per hour over 2018, but the launch angle did not change, so this big surge is a credit to his overall approach rather than any one change. Projecting a third season of 700-plus plate appearances would be very dangerous, and the 2019 season really stands out from the consistently average production Semien had from 2015-2018. The real Semien is in between those two stat lines. If you project another level for him, you're saying he's a top-10 player.
Want to win a bet? Ask, "What nine players have double-digit homers and steals each of the last four seasons?" Most would miss Semien. Granted, his totals lag behind the others, but there's something to be said for reliability and consistency in today's landscape. Semien is two years removed from 2016's 27 homers, rendering it a likely outlier. The rest of his skill set is stable, save for an improving contact rate. This bodes well for a batting average limited by a weak hard-hit rate, supported by Statcast's exit velocity and barrels data. One element of Semien's game that's improved greatly is defense. Once a major liability, Semien's range and throwing took a huge step forward this past season, ingraining him at shortstop for the foreseeable future. A winning fantasy roster is about balance. Semien doesn't excel in any particular category, but his reliability offers roster stability so you can take chances elsewhere.
After hitting 27 home runs and stealing 10 bases in 2016, Semien missed 74 games in the first half of 2017 after undergoing surgery to repair a fractured bone in his right wrist. He did his best to erase doubts about his power potential afterward, though, clubbing all 10 of his home runs from last season over the final 74 games. While it doesn't appear that he'll put together a helpful batting average anytime soon - too many strikeouts and flyballs - his walk rate has improved in each of the last two seasons while his strikeout rate has remained almost flat. He's also stolen 10-to-12 bases in his last three seasons, which helps offset his plate woes. Many will fear his cavernous home ballpark, but he doesn't have drastic splits over his career. His improved defense since his horrible 2015 should keep him in a starting spot for Oakland, or whomever they may trade him to. Power-speed combos in the middle infield rarely price themselves as cheap as Semien should be on draft day.
Investors in Semien for 2016 cashed in as he set career highs in plate appearances, home runs, RBI, runs scored and slugging percentage, while he reached double-digit stolen bases for the second straight year. Even his former hatchet-job defense has improved, which should lock him into the lineup, where he mostly hit toward the top down the stretch last year. His production dipped in the second half, but the 19 first-half home runs linger as a reminder of his upside. To reach the next level, the 26-year-old must show he can do anything in the batting average column, which on the back of his weak batting eye and flyball profile doesn't look like an immediate avenue for growth. Speculators are better off hoping he steals more bags if he continues to bat near the top of the order. For owners who can take the batting average hit, Semien will settle in as a midrange shortstop in mixed leagues who could repeat his returns from last year.
Semien, acquired by Oakland in the Jeff Samardzija trade, was slotted into the lineup as the everyday shortstop for the A's. He started the season hot, then struggled in June and July before righting the ship down the stretch. The final product of all those ups and down was useful especially when factoring in his eligibility at three infield positions. The big issue was the astounding numbers of errors he made at shortstop. Semien led all of baseball with 35 errors, eight more than anyone else at any position, but he improved a lot after the A's hired Ron Washington to tutor Semien at short. After a brutal 28 errors in 89 games before the All-Star break, he only made the seven the rest of the season. That second half may have saved Semien's role heading into 2016, and as a speed/power combo at a middle-infield position, his stock may rise steadily throughout the spring.
Expectations were fairly high for Semien entering the 2014 season after he get on base at over a .400 clip between Double-A and Triple-A in 2013. Unfortunately, he might have been rushed to the major leagues too early. Semien was the White Sox's Opening Day second baseman after Gordon Beckham got hurt and served in a utility role after Beckham returned. Semien struck out in 31 percent of his plate appearances, hardly walked and was back at Triple-A Charlotte by June 2. However, the A's saw something they liked and included him in a trade for Jeff Samardzija. In an ideal world, he plays regularly while posting doubles power and an above-average OBP. He'll get a chance to prove he can do that, as he's expected to compete for the starting shortstop job in Oakland.
Semien is the latest White Sox prospect to run the minor league gamut. He finished 2012 in virtual obscurity at High-A, but he found his way into 21 September contests for the big league club. Stellar plate discipline helped him make is way to the top (98:90 BB:K in 137 minor league games), but this skill faded a bit against better pitching (1:22 BB:K in his September audition). His struggles continued into the Arizona Fall League, and he likely needs a bit more seasoning before he is ready for a regular MLB role. Still, the White Sox's lack of depth at third base could force him into action at some point again in 2014.

Latest Fantasy Rumors
Finalist for Gold Glove
2BTexas Rangers
October 18, 2025
Semien is one of three second basemen nominated to win the 2025 Gold Glove Award in the American League, according to MLB.com.
Analysis
The other two finalists at second base are Luis Rengifo and Andres Gimenez. Semien didn't have his best year on offense in 2025, hitting a mere .230 with a .669 OPS, but his glove was excellent once again with plus-5 DRS. He was limited to only 127 regular-season contests and finished the year on the injured list due to a foot injury, but he's expected to be healthy to begin 2026.
