POSADA IN THE FIELD -- Jorge Posada will use a mitt in a game for the first time this season, but it'll be the first baseman's type, not the catcher's model. Posada will start his 16th career game at first base, while Mark Teixeira moves to designated hitter. Posada, for the record, will be batting seventh. Because of Wednesday's 15-inning game, the Yankees didn't take batting practice or infield, which Posada said he'd like to have gotten in advance of his first start at the position (or any real position) this season. Posada played some first in spring training and has been taking grounders there this season. Yankees at Orioles, 7:05 p.m. ET (Watch live)
STRUGGLING -- Andre Ethier is no stranger to streaks this season, lodging a 30-game hitting streak earlier this season. However, his current streak is nothing to brag about. Over the last five games, he's 0 for 17 with five strikeouts. He's just 1 for 6 in his career against tonight's starter, San Francisco lefty Madison Bumgarner. Ethier is hitting just .235/.264/.314 against lefties this season, with all four of his homers coming off right-handers. Since hitting in his 30th straight game on May 6, Ethier is 7 for 42, hitting .167/.239/.238. Giants at Dodgers, 10:10 p.m. ET (Watch live)
DR. JEKYLL AND MR. HARANG -- One of the feel-good stories of April was the return of Aaron Harang. Now with his hometown Padres and away from homer-happy Great American Ball Park, Harang looked like the 2006-07 version of the right-hander, going 4-0 with a 1.88 ERA in his first four starts as a Padre. The Next four starts, well, not so good -- 1-2 with an 8.46 ERA. Tonight he faces a familiar foe, Milwaukee, in his new spacious Petco home. Harang is 5-5 with a 4.65 ERA in 21 starts against the Brewers, but he may fare better when some of those Ryan Braun and Prince Fielder shots miss the seats.
