The Red Sox have lost four of the six games they've played in National League parks this year, and it's easy to see why.
In those four losses, the best offensive team in baseball combined for a paltry six runs. True, they were facing some pretty good pitching and were playing without Carl Crawford and Jed Lowrie, both of whom remain on the disabled list. However, the bat they missed the most is, without a doubt, David Ortiz's.
The slugger is having a monster season with a .305/.385/.571 line with 17 home runs and 20 doubles. Even at 35, he's still one of the most feared hitters in baseball and is a central part of the Red Sox offense.
Of course, he can't play during interleague games because Adrian Gonzalez occupies first base, leaving Francona with no choice but to take Ortiz out of the lineup. The Red Sox did start Gonzalez in right field in the final game of the series just to get Ortiz into the game, but don't expect that to happen again.
There's no real solution for this problem other than for the other bats in the Boston lineup to step up. However, if the Red Sox and Phillies do indeed meet in the World Series, then Boston better have home-field advantage if they want a good chance at taking home the trophy.
