"I wanted to get Buck in there tomorrow," Gaston said on Saturday. "He has a little better average against the guy pitching tomorrow [Baltimore right-hander Kevin Millwood]. One of them was going to catch today and one of them was going to catch tomorrow, so it's no more than that."
Buck -- the Blue Jays' regular catcher -- has hit .438 (7-for-16) in his career against Millwood, while Molina has gone just 1-for-9 in his career against the right-hander. Gaston added that Buck would likely be behind the plate for the next six games, considering the next afternoon game is not until April 17 in Toronto.
Gaston also noted that he does not plan on having Buck or Molina matched up with specific members of the Blue Jays' starting rotation this season.
"No, I don't think it really matters," Gaston said. "I don't really want to get into that, unless I have to. I always try to steer guys away from that."
