Leiter appeared out of the bullpen in Saturday's 5-4 loss to the Mariners, taking a no-decision while striking out six batters and allowing two earned runs on three hits and two walks over four innings.
After starting in each of his prior six appearances with the Rangers on the season, Leiter shifted to the bullpen Saturday while Max Scherzer (shoulder) made his return from the 15-day injured list. Since Scherzer wasn't fully stretched out after making just one rehab start prior to his activation, the Rangers ended up deploying him in tandem with Leiter, with both pitchers covering four innings and tossing 73 and 71 pitches, respectively. Scherzer and Jacob deGrom -- who returned from the IL on Friday -- should have longer leashes in their next outings this upcoming weekend versus Seattle, so Leiter may not be asked to piggyback either pitcher and may instead work in a more flexible relief role.
