Jeremy Hellickson began his tenure as a Washington National as a relative afterthought: a low-risk insurance policy for a franchise with little pitching depth, someone that could be counted on to at least throw strikes in Triple-A and in the Majors if injuries were to occur. Flash forward to mid-April, when A.J. Cole finally lost his ninth life as a Nats prospect and was demoted from the fifth starter role (and traded a week later) in favor of the 31-year old veteran Hellickson. Not much is generally expected from the number 5 guy in a rotation besides staying giving his club some quality innings so as not to destroy the bullpen.
Yet here we stand halfway through May with Hellickson having started six games and the numbers are astounding. 2.20 ERA, 0.86 WHIP, 5.2 K/BB ratio, and while he only has one decision (a win), the Nats are 4-2 in his starts. Save perhaps the otherworldly Houston Astros, no team in baseball has been as pleased with their fifth starter as Washington. But is it sustainable to any extent? Let’s look at the underlying numbers.
