"Salty is going to rest all day today and not take batting practice," said manager Bobby Valentine. "He had a pretty good spasm and we talked about the situation, and the situation is, 'Let's make sure it's perfect before he gets back in September.' But he wants to play, so it will probably only be a day or two."
The back hasn't been a recurring issue for Saltalamacchia.
"Not many times, no," said Valentine. "He had a little situation, but I'd have to think all the West Coast travel and then coming back, he's a big guy in those [airplane] seats."
Saltalamacchia has caught 85 games for the Red Sox this season while serving as the designated hitter seven times.
