Bourn and McCann are lefties, so that makes sense.
It's the time of year when old guys get the odd extra day off, especially with the Braves flying cross country from here.
Bourn is one of the best leadoff guys and CF's in the game and will be the top CF on the market in a couple of months and McCann is one of the best offensive catchers in baseball, too. Not guys you typically play the L/R matchup game with, IMO. I know no one plays every day but when you're playing the team you're chasing, I'd assume they'd want to put their best lineup out there. So, I'm not sure if this means they're conceding the division a bit and focusing on a tough Giants team coming up tomorrow and holding on to their Wild Card lead or what?
