Arrieta took the hill in the sixth with 65 pitches and only one run allowed, White Sox catcher A.J. Pierzynski's solo homer, but the Orioles defense committed three errors behind him, leading to a pair of unearned runs. The 26-year-old Arrieta struck out seven and was charged with four runs (two earned) on seven hits and a walk.
"There was an eight- or nine-inning outing there last night for him, just couldn't secure the baseball behind us some and elongated some innings," manager Buck Showalter said on Tuesday afternoon. "[Arrieta has] been solid. I think his command is the first thing that you see that he's better with the repair work done to his elbow. You can tell he's freer about attacking the strike zone and knowing where the fastball is going. Because it all works off the fastball."
Arrieta, who was shut down last August and had a bone spur removed from his right elbow, was a full-go this spring and earned the Orioles' Opening Day nod, his second consecutive season pitching the home opener. In his first three starts, Arrieta is 1-0 with a 2.66 ERA, allowing only six earned runs on 14 hits and four walks over 20 1/3 innings. Arrieta has also struck out 16.
