2025 Fantasy Outlook
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. Read Past Outlooks
Inks five-year extension
Pfaadt signed a five-year, $45 million contract extension with the Diamondbacks on Friday that includes a club option for 2031 and a mutual option for 2032, Jesse Friedman of GoPHNX.com reports.
ANALYSIS
Pfaadt's extension won't kick in until 2026, but it will buy out all three of his arbitration years and possibly his first three years of free agency if all options are exercised. The 26-year-old finished last season with a 4.71 ERA and 1.24 WHIP alongside a 185:42 K:BB in 181.2 innings (32 starts); however, his 3.60 FIP is much more indicative of how well he performed on the mound. His first start of the new year is slated to come Saturday versus the Cubs, against whom he allowed two earned runs over 14 innings with a 13:1 K:BB in two appearances last season.

Past Fantasy Outlooks
2024
2023
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.

Latest Fantasy Rumors
Possible trade candidate
The Diamondbacks could trade Pfaadt during the offseason, per Will Sammon and Patrick Mooney of The Athletic.
ANALYSIS
Pfaadt won't be eligible for his first year of arbitration until 2027, so he could be targeted as a cost-controlled starter. The 26-year-old righty had a 4.71 ERA, 1.24 WHIP and 185:42 K:BB over 181.2 innings during 2024, though teams could view him more favorably due to a 3.58 xFIP.
