Chad Sobotka

Sobotka was one of many young Atlanta arms to debut last season with promising results. He doesn't have the hype of some of the Braves' more heralded young pitchers, as his results came in just 14 relief appearances, but it's hard to ignore a 1.88 ERA and 36.2% strikeout rate. There are reasons to be cautious, as his walk rate was quite high at 15.5% and he benefited from a clearly unsustainable .115 BABIP and an equally unrepeatable 98.2% strand rate. Still, with an xFIP of 3.38 and a SIERA of 3.36, the ERA estimators agree that he looks like a capable reliever already. The 25-year-old was included on the Braves' NLDS roster despite not debuting until August -- a good sign for his chances of making the Opening Day roster. It would take a few injuries to get him save chances.
