In Terry Francona's post game press conference he said that Jon Lester will will start game 1, Matsuzaka will start game 2, and Josh Beckett will start game 3 back in Boston.
Beckett apparently strained his oblique muscle on Friday during an indoor bullpen session.
Francona said there were discussions about pitching Beckett in game 2, but they wanted to give him as much time as possible before his next start. Tito didn't seem too concerned about the situation, so I'll sleep easy tonight.
More on this as the story develops, but it looks minor at 11pm on Sunday night.
Also the times of the first two games against the Angels have been announced. Game 1 against the Angels will be on Wednesday at 10:07 p.m. Game 2 will be played Friday at 9:37 p.m. TBS is carrying both games.
