Manager Brad Mills said Buck simply needs to get some at-bats, and it doesn't hurt he's been swinging a hot stick.
"He's a professional hitter," Mills said. "He's got a good approach. That's the best way to describe him."
Buck, who made the team out of Spring Training as a non-roster invitee, had four hits in 12 at-bats entering Monday, including a single, a double and a triple in five pinch-hit plate appearances. Mills has been impressed with Buck's all-around game, not just his bat.
Bogusevic, also a left-handed hitter, has struggled this season at the plate (4-for-29 entering Monday), but Mills isn't ready to make any wholesale changes to his lineup this early in the season.
"As a manager, I don't want to shut the door on anybody, whether it's a guy that came out of spring as an everyday player or a bench guy coming out of Spring Training," he said. "You give them the opportunity if they're able to have a really good ballgame."
