Blows save in critical loss
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.

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.
