Before Tuesday's game, manager Terry Francona huddled with both Matsuzaka and Martinez in hopes they can have better results going forward.
In Matsuzaka's previous outing, when he was brilliant for seven innings in a win over the Blue Jays, Jason Varitek was behind the plate. Martinez caught Matsuzaka's three other starts, in which one extremely bad inning has been the culprit on each occasion.
"We're trying to, as we do during the game, make adjustments, make sure everybody's all on the same page," Francona said. "My point to both of them was, 'OK, if we're frustrated, how do we make it better?' It's easy to show frustration, but how do you make it better? That's what we'll try to do."
Matsuzaka shaking off Martinez isn't the issue, said Francona.
"I don't think I ever have a problem with the pitcher shaking [off] to get to the pitch they want to throw," Francona said. "I don't think Victor does either. I think that was the point he was making. I feel like, for the most part, with our staff, regardless of what pitch they throw, if they throw it with conviction and locate, it's probably going to be the right pitch. We can talk about game-planning, and we certainly do. But again, if guys throw a pitch with conviction, it's probably going to be the right pitch."
Dice-K's next start is scheduled for Saturday at Philadelphia. Who will be behind the plate?
"Well, I'm not going to make the lineup out five days from now," Francona said. "That's impossible."
With Josh Beckett pitching on Tuesday, Martinez served as the catcher. Varitek had caught Beckett's previous six starts.
"We're just trying to win games," Francona said. "I think I said a long time ago that we really didn't want to have too many personal [pitcher-catcher matchups]. I meant that."
