Brandon Pfaadt

27-Year-Old PitcherRP
Arizona Diamondbacks AAA
2026 Fantasy Outlook
Where Pfaadt's results in 2024 (4.71 ERA) didn't reflect expectations (3.78), he earned every penny of his 5.25 ERA last season. The 27-year-old experienced dramatic highs and lows, allowing at least six earned runs in six outings and throwing a tidy nine-inning shutout in September. Pfaadt tinkered with his pitch mix, increasing the frequency of his secondary offerings at the expense of his four-seamer, probably due the Run Value of his four-seamer dropping from plus-7 to minus-2. The right-hander excelled at preventing walks (4.8 BB%), but his K% dropped five points to 19.2 percent in 2025. That suggests poor location in the zone and hitters made him pay (63.2 strand rate). An effective put-away pitch was lacking last season. The Diamondbacks still see the good in Pfaadt but need him to be better in 2026, when Corbin Burnes (elbow) will be unavailable until the second half, and free agent Zac Gallen could be pitching elsewhere.

From Preseason
#376
ADP
Signed a five-year, $45 million contract extension with the Diamondbacks in March of 2025. Contract includes $21 million team option ($1 million buyout) for 2031 and $25 million mutual option ($1 million buyout) for 2032.
Optioned to Reno
PArizona Diamondbacks  AAA
June 4, 2026
The Diamondbacks optioned Pfaadt to Triple-A Reno on Thursday, Steve Gilbert of MLB.com reports.
Analysis
Manager Torey Lovullo said Wednesday that Pfaadt could be stretched out into a starter in the near future, and his demotion to Triple-A suggests that the D-backs are already putting that plan into motion. While the 27-year-old works on building up his workload, Kade Strowd and Philip Abner will come up from Reno to fill the open spots in Arizona's bullpen.

Past Fantasy Outlooks
2025
2024
2023
Don't be discouraged by Pfaadt's bloated 4.71 ERA; all the estimators peg it at least a run better. He was victimized by a low 64.5 percent left on base mark. The righty improved his strikeout and walk rates last season while fixing the gopheritis plaguing him in his rookie year. Pfaadt adjusted his pitch mix, throwing more sinkers at the expense of four-seam fastballs. In 2023, his change-up generated a negative Fangraphs Pitch Value, but last year it rated as Pfaadt's second best offering, though he used it only 11.2 percent of the time. His sweeper sported the highest swinging strike rate of his repertoire. Pfaadt has demonstrated willingness to adjust, and it appears he has the arsenal to fine tune even more. Last season's high ERA could drop his acquisition cost. Buy the floor, and dream on further tweaks elevating Pfaadt to the next level.
Many will point to Pfaadt's postseason and ignore the regular season. While those five starts can't be ignored, Pfaadt foreshadowed his playoff success with a strong second half. After his first six outings, Pfaadt recorded an ugly 9.82 ERA and 1.87 WHIP, with only 21 strikeouts in 25.2 frames. His issue was a 3.2 HR/9 mark. Pfaadt was recalled after the All-Star break and posted a 4.22 ERA and 1.24 WHIP with 73 punchouts in 70.1 innings, with a still high but improved 1.7 HR/9. Pfaadt is a fly ball pitcher, so he'll continue to be homer-prone, but his BABIP should be below average, especially with strong defenders chasing down fly balls in the desert. However, Pfaadt threw fewer four-seamers and more sinkers in the postseason, with a 1.23 HR/9. If he carries this over to his sophomore season, Pfaadt could keep more balls in the yard. The concern in redraft leagues is someone may chase last season's postseason exploits. Expecting a full season of what Pfaadt did over the second half is the sage approach.
Perhaps a sleeper in shallower redraft leagues, Pfaadt is now an in-demand pitching prospect in dynasty and draft and hold formats after he built up to 167 innings and had a very strong showing in the hitter-friendly Pacific Coast League. Among PCL pitchers with at least 50 innings, Pfaadt ranked third in ERA (2.63) and first in WHIP (0.99) and K-BB% (24.8%). Nobody was all that close to him in WHIP or K-BB%, so it's safe to say that Pfaadt was the best pitcher in the league. The 6-foot-4 righty has a well-rounded pitch mix, featuring a mid-90s fastball with good ride, a plus slider with sharp bite and a solid changeup. Most scouts have him pegged as a No. 3 or No. 4 starter in real life, but the stats suggest there might be a little more here. He won't have any workload restrictions in 2023 and could crack the big-league rotation out of spring training.

Latest Fantasy Rumors
Being stretched to start
PArizona Diamondbacks  AAA
June 4, 2026
The Diamondbacks are optioning Pfaadt to Triple-A Reno to stretch him as a starter, according to Nick Piecoro of The Arizona Republic.
Analysis
Manager Torey Lovullo said Wednesday that Pfaadt could be stretched out into a starter, and the plan seems to be in motion already. Pfaadt was sent to the bullpen earlier this season, but the Diamondbacks seem ready to give him another chance to start. His move to the bullpen didn't pan out as hoped, as the right-hander posted a 5.91 ERA across 10 relief outings.
