2025 Fantasy Outlook
Mikolas has permitted more than 10 hits per nine innings two years in a row. No one in baseball has surrendered more base knocks over that time and only Patrick Corbin (5.41 ERA) has a worse ERA among qualifiers than Mikolas' 5.04 mark. The right-hander doesn't even induce ground balls at an above-average clip anymore, as he has just a 40.3 percent ground ball rate over the last two seasons after producing a 47.4 percent rate in his first four years with the Cardinals. Mikolas has made at least 32 starts three years running and is set to make $18.5 million in 2025 in his final year under contract, so he's a good bet to open the year in the St. Louis rotation. He doesn't bring much of anything to the table for fantasy, however. Read Past Outlooks

PSt. Louis Cardinals
March 31, 2025
Mikolas did not factor into the decision Monday against the Angels, pitching 5.1 innings while allowing two runs on two hits and two walks. He struck out three.
ANALYSIS
The grizzled veteran entered this outing on the heels of a solid 19.2 innings in the Grapefruit League, pitching to a 3.66 ERA and 1.27 WHIP. Mikolas limited the Angels to two singles and two free passes, allowing both runs on sacrifice flies. The 36-year-old will struggle to produce many strikeouts, as his K/9 has not been above 7.0 since 2019, but he could be viable in deeper leagues if he can limit hard contact and walks. Mikolas will look to continue the respectable work from this appearance in his next start, currently slated to be at Boston this weekend.

Mikolas has been a solid big-league starter for the Cardinals since returning stateside in 2018 following a three-year run in the Korea Baseball Organization. Overall, he's registered a 3.78 ERA and 1.16 WHIP across 833 innings for St. Louis while managing a stingy 1.6 BB/9. He's topped 200 innings each of the last two years and has been a two-time All-Star wearing the birds on the bat. That all sounds nice, and is nice, but Mikolas is only a borderline option in fantasy because he allows too many balls in play and doesn't generate enough swing-and-miss with his pitch-to-contact approach. He made the most starts (35) in the majors last season but also surrendered the most hits (226) and struck out only 137 of the 860 batters he faced. Mikolas can offer volume, but it's not always the kind of volume you want in a standard scoring league.
Now a two-time All-Star since transitioning back to Major League Baseball after a three-year run in Japan, Mikolas is not afraid to attack hitters. He fills up the strike zone -- Mikolas posted a 4.8 BB% last season -- while using his four-seamer, slider, sinker and curveball all at least 20% of the time. Hitters can't really guess against him, making him a tough plate appearance even if the stuff is modest (19.0 K% last season). The right-hander was forced to miss the shortened 2020 season due to a flexor tendon injury and missed extended time in 2021 with a calcification of that same flexor tendon. The fact that he was able to rebound for a 202.1-inning season suggests he's fine from a health standpoint, but the recent injury history should be accounted for when projecting innings. Drafting him to be much more than a streamer is ill advised.
Mikolas has a 3.54 ERA, a 1.15 WHIP and 29 wins in 429.1 innings with the Cardinals and is a lock for the rotation. That alone makes him a viable source of innings in deeper mixed leagues, especially given the Cardinals' division and home park. His 18.3% strikeout rate over that span is mediocre, but his 4.1 BB% is excellent. This pitch to contact style works well in St. Louis, given the quality of the defenders behind him.
Mikolas ended 2019 with a sore flexor tendon which lingered into the spring. An MRI revealed no ligament damage, so he ramped up slowly and would not have been ready for the original Opening Day. After continuing to throw bullpens over the summer and into camp, Mikolas was expected to return for the delayed start to the season. However, the injury recurred, requiring season-ending surgery. Mikolas' calling card is control as his 18.4 K% and 3.9 BB% since returning from overseas suggests. The 32-year old relies on a high groundball rate to minimize homers, though it didn't help in 2019. Mikolas could be relied upon for close to six innings, a rarity in today's game. This is all now a big question after surgery, plus such a long time since he last took the hill in an MLB game. If healthy, Mikolas should be in the Cardinals' rotation, but without a high strikeout rate, his margin for error is thin.
Not much changed with Mikolas from his first season back stateside in 2018 to 2019, except the home runs. His K% and BB% were near carbon copies of his 2018 marks and his swinging-strike rate was identical at 9.6%. It wasn't a sizable dip, but Mikolas' groundball rate dropped to 47.4%, and the balls that got up did more damage thanks in no small part to the reduced drag on the big-league baseball. His win total was cut in half and his fantasy value took a good hit as a result of these factors. Now 31, Mikolas has a pretty clear fantasy ceiling given his limited strikeout ability, and while excellent command and control have kept his floor high, that floor has been jeopardized by a sore flexor tendon in spring training. If he gets healthy and the ball is deadened some this year, Mikolas could settle into a mid-to-high 3.00s ERA with a WHIP in the teens and double-digit wins on a competitive team.
Mikolas' 2018 campaign was better than even the most optimistic league-equivalency estimators could have predicted after he made the jump from Japan. He was supposed to be pretty good, but he certainly wasn't expected to be this good, finishing with a 2.83 ERA, 18 wins (tied for most in the NL) and a sixth-place finish in the NL Cy Young race. He looks to be a legitimately good starter, with his primary skill being his impeccable control, which allows him to offset a modest 18.1% strikeout rate with an excellent 3.6% walk rate, the best among qualified starters. Mikolas was also good at limiting the long ball, with a near-50% groundball rate leading to a 0.72 HR/9. None of his peripherals suggest that major regression is coming, though the variability of wins means he's unlikely to repeat such a high number in that category, taking away some of his fantasy value. Still, Mikolas is for real and should be treated as a high-floor option this draft season.
Mikolas returns stateside in 2018, having signed a two-year deal with the Cardinals after three highly successful seasons in Japan. But will that success translate? The right-hander flopped in his first pass through the majors from 2012-14, posting a 5.32 ERA and 1.42 WHIP over 91.1 innings between San Diego and Texas. He found his way with the Yomiuri Giants, with his K/9 ticking up from 6.6 to 8.2 to 9.0. Mikolas was also much sharper with his control, issuing a total of 69 free passes in 424.2 innings. The curveball passes the eye test, but for Mikolas it's more about getting that pitch over for strikes than it is the swing and miss. Maintaining the confidence that he gained in his slider and cutter will be crucial to his success in a starting role with St. Louis, and to his chances of exceeding 7.0 K/9, a number he failed to reach in any of his first three big-league seasons.
The Rangers couldn’t have envisioned using Mikolas for 10 starts in 2014, but that is just how severely injuries ripped through their rotation. He closed in Triple-A in 2013 and that was his fourth straight year as a full-time reliever. He wasn’t as bad as his 6.44 ERA would suggest, but three shellackings of seven, nine, and 10 earned runs destroyed him. There was a measure of bad luck involved (namely an impossibly-low 58% LOB rate), but he deserves plenty of the blame for the poor performance. He allowed way too much contact with a 15 percent strikeout rate and was probably fortunate to yield just a .299 BABIP. There were some things to like here, but you are going to have a hard time finding any real fantasy value in him unless your league’s player pool includes the Yomiuri Giants. The rights to Mikolas were sold to the Japanese Central League team back in November.
Mikolas acted as Triple-A Tucson's closer in 2013 but was nothing special, posting 26 saves with a 3.25 ERA and 5.9 K/9 in 61 innings (54 outings). As he climbed the minor league ranks, his strikeout rate tailed off, likely spurring the Padres to cut ties with the 25-year-old right-hander. Following his arrival in the Texas organization, he'll provide depth to the bullpen and likely take up residence at Triple-A Tucson after spring training.
Mikolas finally made his MLB debut in 2012 as he pitched 32.1 innings out of the bullpen with results (3.62 ERA) that really don't reflect how poorly he performed (4.52 xFIP). In the minors his control became less and less sharp as he moved up in levels. His strikeout rate stayed fairly consistent throughout these stops, but has never been anything special. Overall, he's got fringe command and should not be expected to factor into late-game situations in 2013 for the Padres.

Latest Fantasy Rumors
Could be traded
PSt. Louis Cardinals
November 3, 2024
According to Katie Woo of The Athletic, the Cardinals may look to trade Mikolas during the offseason.
ANALYSIS
The veteran right-hander has a full no-trade clause with a $17.67 million salary for 2025, which is the final year of his contract. Mikolas had a 5.35 ERA and 1.28 WHIP over 32 starts in 2024, so the Cardinals could have some difficulty finding interested suitors at that salary.
