2025 Fantasy Outlook
Leiter had one of the most devastating splitters in the league in 2024, ranking second for that pitch type with a 56.5 percent whiff rate and .099 batting average allowed. The split-finger fueled the 33-year-old righty to a career-high 86 strikeouts in just 58 innings between the Cubs and Yankees. However, Leiter was not effective after the mid-season trade to New York, struggling to a 4.98 ERA and 1.71 WHIP with six home runs allowed over his final 21.2 frames. He's projected to take on a middle relief role for the Yankees in 2025. Read Past Outlooks

Leg
July 8, 2025
The Yankees placed Leiter on the 15-day injured list Tuesday with a left fibular head stress fracture.
Analysis
Per Max Goodman of NJ.com, Leiter felt a pop in his left leg when he was running to cover first base in a game versus the Reds back on June 24. He had made four appearances since then, but testing revealed the stress fracture. It's not clear how long Leiter might be out, but it's likely to be longer than a minimum stay on the IL.

Stat Review
How does Mark Leiter compare to other relievers?
This section compares his stats with all relief pitcher seasons from the previous three seasons (minimum 30 innings)*. The bar represents the player's percentile rank. For example, if the bar is halfway across, then the player falls into the 50th percentile for that stat and it would be considered average.

* Exit Velocity, Barrels/BBE %, Balls Hit 95+ MPH %, and Spin Rate are benchmarked against 2019 data (min 30 IP). See here for more exit velocity/barrels stats plus an explanation of current limitations with that data set.

Past Fantasy Outlooks
2024
2019
2018
Leiter re-signed with the Cubs on a minor-league deal last February and secured a spot on the Opening Day roster with a strong spring. After spending much of the 2022 season in a multi-inning relief role, the 32-year-old locked down setup duties for Chicago and finished the season with 28 holds (T-5th in the league). Leiter rode the success of his splitter (.134 BA, 48.2% whiff percentage) to career-best ratios and a 28.6% strikeout rate, with 65 of his 77 total strikeouts coming on the pitch. He threw the splitter at a career-high 34% clip, which was +11.3% difference from the season prior. Leiter's secondary offerings aren't as effective, but he mixes five pitches to keep hitters guessing. The right-hander also tallied four saves to give the Cubs another option to turn to when closing out games. Leiter, who is arbitration eligible for the first time, figures to reprise his setup role for the Cubs after he was recently tendered a contract for 2024.
After he posted some decent peripherals in 2017, a forearm strain and poor performance limited Leiter to just 23.1 innings last season. The 27-year-old spent time with both Philadelphia and Toronto but failed to impress for either organization, finishing with an ugly 7.71 ERA. His numbers fell across the board, with his strikeout rate falling to 17.9% while his walk rate rose to 9.8%. He surrendered a home run on a full 25% of opposing hitters' flyballs. That number -- along with his .350 BABIP and 53.6% strand rate -- can be taken as a sign of bad luck, but even with some positive regression, Leiter looks like a low-leverage reliever at best. The Blue Jays outrighted him off the 40-man roster in November. He could eventually work his way into a long-relief role this season, but his odds of producing fantasy-relevant numbers are slim.
Leiter started 11 games and appeared in another 16 out of the bullpen in his rookie season. He put up a somewhat poor 4.96 ERA in his 90.2 innings, though the underlying numbers suggest that he should be a roughly league-average pitcher going forward. His 8.3 K/9 exactly matched the league average, while his 3.1 BB/9 and 48.9 percent groundball rate were both slightly above average. His poor ERA looks to be mostly a result of an unlucky HR/FB rate, as 21.7 percent of the flyballs he gave up left the park. If that number falls back, as it should, Leiter could put up an ERA closer to what his xFIP said it should have been last year (4.19), making him a viable but low-ceiling back-end starter. The Phillies have a number of young starters with similar track records, but Leiter has a better shot than most to provide acceptable production if given the opportunity.

Latest Fantasy Rumors
No issues from arb hearing
PNew York Yankees
February 14, 2025
Leiter said Friday there's "no hard feelings" with the Yankees after he lost his arbitration hearing, reports Brendan Kuty of The Athletic.
Analysis
Arbitration hearings can sometime result in bad blood between organization and player, but that's not the case for Leiter. The right-hander filed for a $2.5 million salary, but the arbitrators sided with New York's $2.05 million figure. Leiter split last season between the Cubs and Yankees and had a 4.50 ERA, 1.33 WHIP and 86:22 K:BB across 58 regular-season innings.
