"There are still some issues, and I'm trying to match up a little bit maybe as well. With Blummer, getting Blummer in there against some matchups I think would be good for him and, of course, good for us as well as a team," manager Brad Mills said.
Blum, who has made 21 starts overall this year, doesn't plan to change his approach despite getting more starts at shortstop.
"I take ground balls at shortstop all the time and just try to stay in shape," he said. "[Mills] hinted early in the spring I might be getting in against tough righties and giving Tommy a break. He does a pretty good job telling us where we're playing the day before, so my job is to be ready anytime, anywhere."
