Rzepczynski, 32, had signed a two-year deal with the Seattle organization before the 2017 season. He’s earning $5.5MM this season under that contract.
Needless to say, the signing has not really turned out as hoped. This year, he has recorded just 7 2/3 innings in his 18 appearances, allowing eight earned runs on 13 hits while carrying a brutal 10:9 K/BB ratio.
Like most of his prior employers, the M’s have tried to limit Rzepczynski to facing left-handed hitters. And he has largely held them in check, as opposing southpaw swingers own a .222/.323/.333 slash against him this year. But Rzepczynski has been completely helpless in 2018 when facing righties, who have gone 7-for-11 with two home runs and five walks.
That sort of output represents a problem even for a LOOGY, as it’s hard to avoid righties altogether. Rzepczynski has been tagged for a .280/.386/.438 cumulative lifetime slash by hitters that carry the platoon advantage, which has been at least palatable enough given the sub-.600 OPS he has allowed over his career to lefties.
