Brian Matusz left his start against the Nationals this afternoon in the sixth inning with left hamstring cramps, reports Jeff Zrebiec of the Baltimore Sun. Fortunately for the Orioles, the young left-hander is considered day-to-day.
Matusz allowed four runs on six hits (including two long homers to Ryan Zimmerman and Michael Morse) over 5 1/3 innings before leaving the game. He struck out five and walked three while throwing 52 out of 90 pitches for strikes.
Matusz missed the first two months of the season with a strained intercostal muscle. Including today’s outing, he has a 5.60 ERA and 11/9 K/BB ratio over his first four starts.
