Blows save in critical loss
PChicago Cubs
September 27, 2023
Leiter allowed a run on two hits while retiring only one batter to record a blown save in Wednesday's extra-inning loss to Atlanta.
ANALYSIS
Leiter got a crack at the ninth inning with the Cubs up 4-3, but he allowed a Marcell Ozuna home run to record his fourth blown save of the season. With regular closer Adbert Alzolay (forearm) on the injured list, Leiter has failed to step up, as he now has an ugly 9.45 ERA this month. The Cubs will likely need to turn to Julian Merryweather in save opportunities for the time being considering the magnitude of their next four games.

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
2019
2018
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.
