The Red Sox announced their roster about four hours before game time on Friday. As expected, they went with 14 position players and 11 pitchers.
The catchers are Jarrod Saltalamacchia and David Ross. The infield is Mike Napoli, Dustin Pedroia, Stephen Drew, Will Middlebrooks and Xander Bogaerts. David Ortiz is the designated hitter. The outfielders are Jacoby Ellsbury, Shane Victorino, Daniel Nava, Jonny Gomes, Mike Carp and Quintin Berry.
With lefty Matt Moore starting, Gomes got the nod over Nava in left field. Berry essentially won the final spot on the bench because of his speed. He has never been caught stealing in 26 attempts, two of which came for the Tigers in last year's postseason.
Beyond the four pitchers (Jon Lester, John Lackey, Clay Buchholz and Jake Peavy ) who will start in this series, the Sox have seven relievers. Closer Koji Uehara will be complemented by right-handers Junichi Tazawa, Brandon Workman and Ryan Dempster. Doubront is the third lefty, joining Craig Breslow and Franklin Morales.
In the end, Doubront beat out veteran lefty reliever Matt Thornton.
"We looked at Felix's ability to give us multiple innings," said Farrell. "If we were to get in a situation where it was a lengthy rain delay and we need multiple innings to start back up. ...It was more the ability to go multiple innings and a guy who has had a very good year for us."
When Doubront is on his game, his stuff can be nasty. For the second straight season, fatigue seemed to set in and he struggled in his starts down the stretch.
The Red Sox have challenged him to alter his offseason routine to avoid that happening next year.
