The Boston Red Sox, a season removed from a world championship, are set to open the 2015 regular reason today in Philadelphia against the Phillies, the first time in team history that Boston will open against a National League opponent. The Red Sox, who followed the 2013 championship season with a last place finish in the American League East, the second such finish in three seasons, will be managed for a third year by John Farrell. Boston will play an additional road series in New York against the Yankees before opening Fenway Park next Monday versus the Washington Nationals.

Many familiar faces return from last season, including designated hitter David Ortiz, who will start the opener at Citizens Bank Park as the first baseman, first baseman Mike Napoli, second baseman Dustin Pedroia, shortstop Xander Bogaerts, outfielder Shane Victorino, and starting pitcher Clay Buchholz. Another familiar face who returns as a starter this season is outfielder Mookie Betts, who will likely play his first full season at the major league level and has already drawn interest as a dark horse MVP candidate.

Some of the new faces are already familiar to fans of the Boston nine. Outfielder Hanley Ramirez, who came up through the Red Sox farm system as a shortstop and appeared in two games with Boston before being part of a trade in November 2005 for Josh Beckett and Mike Lowell, returns to the fold, as does starting pitcher Justin Masterson, who appeared in 67 games for Boston in 2008 and 2009. Other new players include third baseman Pablo Sandoval, who played for seven seasons in San Francisco and won three World Series with the Giants, including last season, and pitcher Rick Porcello, who came as part of a trade with Detroit for Yoenis Cespedes.

Here is the complete Opening Day roster for Boston:

Pitchers (12)
Clay Buchholz, Rick Porcello, Justin Masterson, Wade Miley, Edward Mujica, Junichi Tazawa, Anthony Varvaro, Alexi Ogando, Craig Breslow, Robbie Ross Jr., Steven Wright, and Tommy Layne

Catchers (2)
Ryan Hanigan and Sandy Leon

Infielders (5)
Mike Napoli, Dustin Pedroia, Xander Bogaerts, Pablo Sandoval, and Brock Holt

Outfielders (5)
Hanley Ramirez, Mookie Betts, Shane Victorino, Daniel Nava, and Allen Craig

Designated Hitter (1)
David Ortiz

Closer Koji Uehara, starting pitcher Joe Kelly, and relief pitcher Edwin Escobar will begin the season on the 15-day disabled list. Catcher Christian Vazquez, who had Tommy John surgery on his right elbow last week, will miss the entire 2015 season.

Many familiar faces remain on the roster from last season, including designated hitter and World Series MVP David Ortiz, second baseman Dustin Pedroia, outfielder Shane Victorino, starting pitchers Jon Lester, John Lackey, and Clay Buchholz, and closer Koji Uehara. Another familiar face who returns as a starter will be shortstop Xander Bogaerts, who is the youngest player to open the season at that position for the Red Sox since Everett Scott in 1914, according to Gorden Edes at ESPNBoston.com.

Some of the new faces include veteran catcher A.J. Pierzynski, outfielder Grady Sizemore, and reliever Edward Mujica. In what was a relatively quiet spring, Sizemore was the big story; returning to baseball after being limited to 112 games between 2010-2011 and no games over the past two season, he outperformed expectations and displaced Jackie Bradley, the expected starting center fielder, from the major league roster.

Here is the complete Opening Day roster for Boston:

Pitchers (12)
Burke Badenhop, Clay Buchholz, Chris Capuano, Felix Doubront, John Lackey, Jon Lester, Andrew Miller, Edward Mujica, Jake Peavy, Junichi Tazawa, Koji Uehara, and Brandon Workman

Catchers (2)
A.J. Pierzynski and David Ross

Infielders (5)
Xander Bogaerts, Jonathan Herrera, Will Middlebrooks, Mike Napoli, and Dustin Pedroia

Mike Carp, Jonny Gomes, Daniel Nava, Grady Sizemore, and Shane Victorino

Designated Hitter (1)
David Ortiz

Pitchers Craig Breslow and Steven Wright will begin the season on the disabled list.

The 2013 squad features many new faces, including starting pitcher Ryan Dempster, closer Joel Hanrahan, first baseman Mike Napoli, who will be making the transition from catcher for the Sox, and outfielders Jonny Gomes and Shane Victorino. Another new face is rookie Jackie Bradley, Jr., who impressed coaches and fans alike this spring and, with the absence of David Ortiz due to injury, has been given the opportunity to start the season on the 25-man roster, having never played higher than Double-A in his brief minor league career.

Of course, several familiar faces remain, including pitchers Clay Buchholz, John Lackey, and southpaw Jon Lester, who will square off against CC Sabathia at 1:05 PM this afternoon, catcher Jarrod Saltalamacchia, second baseman Dustin Pedroia, third baseman Will Middlebrooks, and outfielder Jacoby Ellsbury.

Former Red Sox pitching coach John Farrell, who piloted the rival Toronto Blue Jays over the past two seasons, takes over for the departed Bobby Valentine as manager.

Here is the complete Opening Day roster for Boston (asterisk denotes today’s starters):

Pitchers (12)
Alfredo Aceves, Andrew Bailey, Clay Buchholz, Ryan Dempster, Felix Doubront, Joel Hanrahan, John Lackey, Jon Lester*, Andrew Miller, Clayton Mortensen, Junichi Tazawa, Koji Uehara
