Buck, who is 5-for-7 with two doubles and a triple as a pinch-hitter, started in right field in the series opener against the Marlins in place of Brian Bogusevic.
"It's funny because people always say since I'm doing such a good job as a pinch-hitter right now, that's what my role might be, but I look at it as whenever I'm in the lineup, it's a great to get multiple at-bats," Buck said. "It can get kind of tough sometimes if you're pinch-hitting if you're not getting the at-bats every day and not seeing live pitching."
Buck entered Monday hitting .297 with a .366 on-base percentage and says he comes to the ballpark prepared to pinch-hit or start.
"The good thing about this team, and especially being in the outfield with Bogusevic, is we can kind of mix and match in a sense where each guy can get a couple of starts and see what they can do to get on a roll," Buck said. "I had my chance the first couple of games in Washington [April 16-17] and unfortunately I went down with a hamstring problem. It's a matter of taking it day by day and continuing to have good at-bats and get on base."
