OAKLAND -- Mark Trumbo hit his first grand slam of the year as part of a five-RBI day, and Chris Tillman won for the 15th time, as the Orioles held off a late A's surge and avoided a sweep at the Coliseum on Thursday with a 9-6 win.
Baltimore's offense finally erupted after scoring only three runs through the first three games of the series. A three-run fourth, capped by a two-run double by Pedro Alvarez, snapped a scoreless streak of 17 consecutive innings dating back to Tuesday. The O's only added on from there, loading the bases an inning later for Trumbo, who hit his Major League-leading 32nd homer and third career grand slam to make it 7-0.
