Mariners rookie Matt Brash might already be the filthiest pitcher in baseball

Mariners pitcher Matt Brash made his big-league debut on Tuesday despite never pitching beyond Double-A, and it was pretty easy to see why Seattle wanted that arm with the MLB squad right away.

He certainly knew how to make a first impression.

Brash came into Tuesday’s game against the White Sox with a 2.28 minor-league ERA and striking out 13 batters per nine innings. On top of that, the Padres traded him to Seattle as an afterthought for now-Giants minor leaguer Taylor Williams. Brash’s electric fastball and knuckle curveball turned heads during spring training, and he brought that energy into his MLB debut with a ridiculous first inning.

Brash struck out two of the three batters he faced (Tim Anderson managed to fly out on an 0-2 count) in the first inning, and he made Luis Robert and Jose Abreu look silly in the process. He might already be the filthiest pitcher in baseball.
