Now, theres a good problem for Buck Showalter. Zach Brittons seven shutout innings in the Orioles 3-2 win against Detroit would seem to secure him a spot in the Orioles rotation. However, the Orioles could go with four starters until Aug. 28 because theyre off next Thursday when Brittons next turn would fall.Britton was only sent to Norfolk because the Orioles overtaxed their p bullpen in a 14-inning win on Aug. 8, and the team recalled him 10 days later for the start.Steve Johnson, who pitched two innings in relief on Thursday was bypassed. Johnson was sent to Norfolk after his first major league start on Aug. 9, but recalled after an ankle sprain shelved Troy Patton.The Orioles are carrying 13 pitchers, and Johnson may be optioned to Norfolk for the fourth time since July 3. Ryan Flaherty should be back soon because the Orioles dont want to work with a three-man bench for long. Chris Davis three-run home run, his first since July 31, his 19th of the season, accounted for all the Orioles runs.The Orioles are now 22-6 in one-run games and equaled a club record with 12 straight wins by a run.Jim Johnson polished off the Tigers on 10 pitches in the ninth for his 36th save.Despite Adam Jones tweets, the center fielder is still looking for career home run No. 100. He hasnt homered since July 27, but singled and scored on Davis home run.Wei-Yin Chen (11-7, 3.70) faces Doug Fister (7-7, 3.24) on Sunday. Game time is 1:05 p.m.
