Osich gave up a run on a pair of hits over 1.1 innings Sunday against the Phillies. Osich's struggles continued Sunday, as he surrendered the lead in the eighth inning of an eventual walk-off win. He has definitely regressed after posting a 2.20 ERA in 2015. While his 4.24 ERA isn't horrid, his 6.13 FIP indicates that he has actually been getting lucky with that ERA. He doesn't strike out a ton of batters and his control is suspect, but the real culprit is his susceptibility to the long ball (1.93 HR/9). His righty-lefty splits are glaring, so manager Bruce Bochy may want to limit his appearances to solely left-handed batters.
Osich surrendered a two-run homer Wednesday. He walked one and struck out two in the extra-inning win over San Diego. Osich has now given up three runs over his last three appearances, seeing his ERA rise from 1.84 to 3.31 over that span. His combination of sub-par control (3.31 BB/9) and susceptibility to the long ball (1.65 HR/9) make him a risky middle-relief option.
Osich has a 1.84 ERA and 0.89 WHIP after throwing 14.2 innings across 21 games this season. While Osich is continuing to lower his ERA and WHIP from the 2.20 and 1.12 that he finished the 2015 campaign with, there are some facets of his game that have regressed. For one, his K/9 is 4.91, nearly half of last season's rate. In addition, his BB/9 is 3.07, as opposed to 2.51 in 2015. While this has resulted in less runs and fewer baserunners, the Giants would surely like to see Osich get back to retiring batters via strikeouts.
Osich has a 2.57 ERA with six strikeouts through seven innings. The hard-throwing lefty has gotten off to a strong start in his rookie season. With a mid-90s fastball (that he grips three different ways) and changeup combo, Osich has the stuff to be a late-inning reliever for the Giants. He will need to keep his walks in check (5.14 BB/9) in order to bring his 3.71 xFIP closer to his 2.57 ERA.
Osich will be a part of San Francisco's Opening Day bullpen in 2016. Osich made his major league debut in 2015, compiling a 2.20 ERA with 27 strikeouts over 28.2 innings. He will fill the left-handed reliever role vacated by Jeremy Affeldt (retirement). While it is unclear whether manager Bruce Bochy will use Osich in high-pressure situations in the same vein as Affeldt, he will definitely be a part of this bullpen in 2016. The 27-year-old southpaw regularly sits in the mid-90s with his fastball and works off of it with his slider and changeup.
