The Year in Tanner Roark
August 7th, 2013: Jordan Zimmermann lasts only four innings in his start against the Braves, giving up seven hits and a couple of runs before Davey Johnson goes to the bullpen. In need of a bridge to the team’s middle relievers, Johnson calls in a rookie, Tanner Roark, to make his Major League debut. It is about as nondescript an appearance as one could imagine, as he faces six hitters, giving up a hit to B.J. Upton — okay, so one remarkable thing happened — but erasing it with a double play, and facing the minimum six batters over his two innings of work.
No one really thought much of it. Even in this post-game interview, Roark looks about as excited in his debut as everyone watching was. He was just a guy, a 25th round pick by the Rangers who was traded to Washington as half of the return for Texas’ acquisition of Cristian Guzman back in 2010. Fun fact; after the trade, Guzman hit .152/.204/.174 and was worth -0.7 WAR in just 50 plate appearances. Whoops.
But, really, giving up Roark wasn’t anything to lose sleep over. When Texas traded him, he was a guy with 75 strikeouts in 105 innings in Double-A, and he wasn’t even avoiding walks that well. He was an organizational guy, a non-prospect with no obvious upside who looked like a career minor leaguer. Even when he got to Washington, he didn’t really have any kind of major breakthrough. He just progressed through up the chain, got to Triple-A as a 25 year old, and then threw enough strikes in Syracuse last year that the team called him up when they needed a long man in the bullpen.
Well, he’s not a long man in the bullpen anymore. Since Roark’s debut one year ago today, here are the top 10 qualified starting pitchers by ERA-.
