Pedro Martinez went 75-26 for Boston from 2000-2004.
No. 1: Pedro Martinez. In 2000, Martinez won the AL Cy Young Award after striking out 284 batters and posting an ERA of 1.74. He signed with the New York Mets following the Red Sox's 2004 World Series win, but in the five previous seasons, he was chosen for two All-Star teams and led the league in ERA on three occasions.
No. 2: Curt Schilling. Schilling spent the final four years of his career in Boston, capturing two championships in the process. In 2004, he went 21-6, made an All-Star appearance and finished second in the Cy Young voting. His "bloody sock" performance in Game 6 of the ALCS that season is one of the most iconic images in Red Sox history.
No. 3: Jon Lester. Now in his ninth year in Boston, Lester has won 15 or more games in five of the past six seasons. He played for two titles-winning teams (2007 and 2013), was selected for a pair of All-Star Games in 2010 and 2011 and threw a no-hitter in 2008.
No. 4: Josh Beckett. Beckett pitched for the Red Sox from 2006 to 2012. In 2007, he won 20 games and finished second in the Cy Young race, also taking home a championship. Beckett was a three-time All-Star in Boston and ended his Red Sox career with an 89-58 record.
No. 5: Tim Wakefield. For Wakefield, this honor is all about longevity. He won 121 games for Boston from 2000 to 2011, the most of any Red Sox pitcher in the 21st century. Wakefield played for two World Series winners, '04 and '07, and was chosen for the All-Star Game in 2009.
Next in line: Derek Lowe. Lowe saved a league-leading 42 games as a closer in 2000, but he also won 21 as a starter in 2002. He made the MLB All-Star Game on both occasions and hurled a no-hitter in '02 as well. During the Red Sox's title run of 2004, Lowe earned the deciding victory in all three rounds of the playoffs.
