What to watch
1. Day-after response. The Orioles had one of their worst games of the season Tuesday, with starter Kevin Gausman struggling, the bats somewhat quiet and the defense mistake prone (Manny Machado committed an error and Welington Castillo had a passed ball). Will the Orioles tighten it up after falling out of sole possession of first place for the first time in a week?
2. Ubaldo, Part 3. In an inconsistent rotation, Ubaldo Jimenez has been the weakest link after two starts. He has the worst ERA among Orioles starters (10.38), having allowed five runs in 4 1/3 innings in each of his two outings. Jimenez has a 3.00 ERA in six career starts against the Reds, but hasn't faced them since 2013. It will be worth watching to see if his first solid outing of the season comes on a night he has to hit.
3. Rising rookie. Rookie left-hander Amir Garrett, 24, has jumped from heralded prospect to post a 1.42 ERA in his first two major league starts with the Reds. Prospect services hadn't quite agreed on how good he is, ranking him as high as No. 32 in baseball to as low as No. 81 entering this year. All of the major publications had him in the top 100, however. He has struck out nine and walked two in 12 2/3 innings with quality-start victories on the road against the St. Louis Cardinals and Pittsburgh Pirates in his first two outings. With Seth Smith out, the Orioles will use virtually the same lineup as they have for left-handers, except with red-hot Trey Mancini batting leadoff.
