Mills said Saturday after the Astros called up Martinez from Triple-A Oklahoma City that he would be the starter in right field, a position Bogusevic has held for much of 2012. Bogusevic is hitting .220 with two homers and seven RBIs this year.
"He just said that, for the near future, he's going to get the bulk of the playing time, which is fine," Bogusevic said. "He's been swinging well before he came up and we're looking to score runs and stuff. It is what it is. I go back to being the left-handed bat off the bench and maybe playing here and there."
This season has been a struggle at the plate for Bogusevic, who homered on Opening Day as the starter in right. He batted .238 (19-for-80) in May with one home run, which came last Monday in Colorado. He hit .287 with four homers and 15 RBIs in 87 at-bats last year.
"It's definitely been frustrating," Bogusevic said of his season. "There's been times where I've felt like I'm about to break through and turn it around and then I go back to not feeling comfortable again. I'm still looking for that extended period of feeling comfortable with my swing. I have to keep working through it."
