== Professional career ==


=== Boston Red Sox ===
The Red Sox selected Lester in the second round, with the 57th overall selection, of the 2002 Major League Baseball draft and gave him the highest signing bonus of any second-rounder that year, $1 million.Lester quickly moved through the Red Sox organization, posting an 11–7 win–loss record, a league-leading 2.61 earned run average (ERA) and a league-best 163 strikeouts for the Portland Sea Dogs of the Class AA Eastern League in 2005. He was named the Eastern League Pitcher of the Year and Red Sox Minor League Pitcher of the Year and was selected as the left-handed pitcher on the Eastern League's year-end All-Star team and on the year-end Topps Class AA All-Star squad.
Lester was one of the Red Sox' top-rated prospects while in the minors, and other major league teams made efforts to acquire him. The Texas Rangers had demanded Lester be part of the proposed but ultimately rejected deal before the 2004 season for Alex Rodriguez. The Florida Marlins insisted he be included in the trade for Josh Beckett before the 2006 season, but again, the Sox were able to keep Lester.


==== 2006 ====
With a rash of injuries and general ineffectiveness of several Red Sox starters, the team recalled Lester on June 10 to make his major league debut against the Texas Rangers. He put up a 7–2 record and a 4.76 ERA in 81+1⁄3 innings pitched in his rookie year.
On August 27, 2006, Lester was scratched from his scheduled start against the Oakland Athletics due to a sore back. The following day he was placed on the 15-day disabled list, and was sent back to Boston for testing. At the time, Lester's back problems were thought to be the result of a car crash he was involved in earlier in the month. On August 31, it was reported that Lester had been diagnosed with enlarged lymph nodes and was being tested for a variety of ailments, including forms of cancer. A few days later, doctors at Massachusetts General Hospital confirmed that Lester had a treatable form of anaplastic large cell lymphoma. Lester underwent off-season chemotherapy treatments at Seattle's Fred Hutchinson Cancer Research Center. In December 2006, ESPN.com reported that Lester's latest CT Scan showed no signs of the disease, which appeared to be in remission.

Following the successful treatment of his lymphoma, Lester was able to return to the Red Sox midway through the 2007 season. Lester attended spring training in 2007, and started the season for the class A Greenville Drive. Lester then started for Triple-A Pawtucket Red Sox in late April 2007. In June, Lester was removed from the disabled list, and sent to Pawtucket for further rehab outings.Lester made his first 2007 start for the Boston Red Sox on July 23 against the Cleveland Indians at Jacobs Field in Cleveland, pitching six innings, allowing two runs on five hits and struck out six, picking up the win. On September 26 against the Oakland Athletics at Fenway Park, Lester gave up what would turn out to be the final career home run by Hall of Fame catcher Mike Piazza. In the 2007 World Series against the Colorado Rockies, Lester won the series-clinching Game 4 for the Red Sox, pitching 5⅔ shutout innings, giving up three hits and three walks while collecting three strikeouts. Lester became the third pitcher in World Series history to win a series clinching game in his first post-season start.To honor Lester's comeback from lymphoma, the Boston Baseball Writers' Association of America voted him the 2007 Tony Conigliaro Award.


==== 2008 ====
On May 19, 2008, Lester threw a no-hitter in a 7–0 win against the Kansas City Royals. It was the 18th no-hitter in Red Sox history. Lester threw 130 pitches in the game, allowing only two walks and striking out nine batters, and was charged with a throwing error on a pickoff attempt in the second inning. It was the first no-hitter thrown by a Red Sox left-handed pitcher since Mel Parnell in 1956, the first in MLB since teammate Clay Buchholz in September 2007, and the MLB-record fourth no-hi
