OAKLAND -- The A's couldn't find a way to sweep the Orioles on Sunday at the Oakland Coliseum but they still managed to win the series. Baltimore took the series finale with 8-4 win. It was an uncharacteristically wild day for the A's pitching staff. They used a season-high seven pitchers and combined for nine walks.Starting Pitching ReportRookie starting pitcher Dan Straily had major issues with Baltimore's catcher Matt Weiters. In the second inning Straily allowed a solo homer on a 2-2 slider to Wieters that looked like it caught a little too much of the plate. Wieters got him again on a fastball, cranking another solo homer to right field to leadoff the fourth inning. The third time Wieters stepped to the plate was in the fifth inning and he was greeted with an intentional walk to load the bases.After walking Wieters, Straily issued a two-out free pass to Mark Reynolds scoring the Orioles' fourth run. That ended his day.A's starting pitchers had walked three or fewer batters in each of their last 44 games which is the longest streak since for the A's since at least 1921. The five walks allowed by Straily snapped the streak. He lasted four and two-third innings, allowed four runs, and five hits.In the third inning Straily gave up a game-tying single on a tough ball hit to Josh Donaldson that the third baseman couldn't come up with.Bullpen ReportTravis Blackley entered with the bases loaded in the fifth inning.
