Mariners to call up RHP George Kirby to reinforce rotation

What’s the MLB equivalent of a WojBomb? A PassanProjectile? PassanPewPewPew? Anyway, we got one:

The Seattle Mariners are calling up right-hander George Kirby, one of the best pitching prospects in baseball, sources tell ESPN. Kirby, 24, is a former first-rounder who dominated at AA this season. Huge stuff, huge ceiling and the Mariners, who are slumping, could use a boost.

The Mariners are indeed slumping, Jeff, thanks for noticing. After demoting the struggling Matt Brash to Tacoma this past week, it wasn’t clear who the fifth starter would be, with most people (read: us) assuming the Mariners would go with a bullpen day, probably anchored by Justus Sheffield.
