Mark Trumbo, who won the 2009 Texas League Home Run Derby, will be one of four American League batters partaking in the State Farm Home Run Derby in Kansas City, and he's not worried about his swing being negatively affected. Thirty out of 40 Derby participants from 2007-11 saw declines in their homers-per-at-bat totals after the break, but Trumbo doesn't play to be the 31st. "I'm a guy that cuts it loose most of the time anyway, so my goal is always to put myself in a position to drive the ball," Trumbo said. "So it's not a huge adjustment for me. I mess around every once in a while and try to launch balls. It's nothing that's terribly out of the ordinary for me." Orioles: Mahoney makes debut
Joe Mahoney went hitless in his Major League debut on Saturday night, batting eighth and starting at first base for the Orioles. Mahoney went 0-for-3 and left one batter on base while Baltimore was shut out, 3-0. In 84 games with Triple-A Norfolk, Mahoney hit .257 with 14 doubles, five home runs and 38 RBIs. "I think he understands that he'll probably head back after the [All-Star] break, but let him get a taste of it before he goes back," manager Buck Showalter said. "With the way we've had some guys banged up, I hope he presents himself well tonight." Worth noting
Mills hasn't been great in 14 career appearances against Major League competition, but he is 2-0 with a 2.19 ERA and nine strikeouts in 12 1/3 innings pitched against Baltimore. Chen was sharp against the Angels in his third career start. He gave up just one run on five hits in 6 1/3 innings on the road.
