Arrieta – who emerged as the front runner for the team’s open No. 5 starter position – pitched six scoreless innings in an eventual scoreless 10-inning tie with Pittsburgh.
Arrieta stranded five runners in scoring position and escaped two-on, one-out jams in both the fourth and fifth innings. Sanchez held the Orioles to two hits – both of them singles by third baseman Manny Machado – in five innings.
