"[Dusty] Baker said left fielder Matt Murton would sit against Mets left-hander Tom Glavine on Friday, but will play Saturday against lefty Kazuhisa Ishii," reports the Chicago Tribune. "Baker said he would try to get Murton at-bats, but he doesn't plan to platoon him with Matt Lawton, as he did with Todd Hollandsworth. 'We're trying to get to the playoffs, so we're going to play whoever I think the best lineup is against that particular guy,' he said."

Baker is making a mistake. Lawton is hitting .236/.328/.358 against lefthanders this year. For his career, he's hitting .250/.343/.372 against lefthanders. Higher production is needed out of your corner outfielders.

But Lawton is safe and predictable. Murton is not.

Still, it is not necessarily a mistake to play Lawton against Tom Glavine. Glavine has allowed a higher batting average against lefthanded batters than righthanded batters this year (.336 v. .310), and that is consistent with his career (.260 v. .255).
