The file on Jon Lester
Jon Lester attended Bellarmine Prep high school in Tacoma, Washington. The lefty was considered a top prospect because of his power arm. Lester's fastball ranged from 88-93 miles per hour. He threw a no-hitter on March 28, 2002 and was named league MVP three times in four years. As a sophomore, he was named the Gatorade State Player of the Year and in his senior season he went 4-2 with a 1.50 ERA.
Although he had committed to play at Arizona State, the Boston Red Sox drafted Lester with the 57th pick in the second round of the 2002 amateur draft. He signed on Aug. 13, 2002 and received a $1 million signing bonus, which was the highest at that time for a second round player. At the age of 18, Lester entered the draft ranked by Baseball America as the eighth-best left-handed pitcher and the No. 1 player to come out of Washington state.
Major league debut
Lester moved up quickly in the Red Sox's minor league system. He won 11 games, posted a league-best 2.61 ERA, and recorded 163 strikeouts in 150 innings for the Class-AA Portland Sea Dogs in 2005. As a result, he earned Eastern League Pitcher of the Year honors and made his major league debut with the Red Sox on June 10, 2006.
Diagnosed with lymphoma
In the same season in which he made his major league debut, Lester learned of troubling news. He went to the hospital and was diagnosed with anaplastic large cell lymphoma, a treatable form of the disease. After treatment, Lester was declared cancer-free in December.
World Series champion
After a 7-2 rookie season and successful treatment of his lymphoma, Lester went 4-0 in 2007. He pitched Game 4 of the World Series against the Colorado Rockies and allowed three hits, three walks and struck out five in a 4-3 win, clinching the title for the Red Sox.
Lester pitched a no-hitter against the Kansas City Royals on May 19, 2008. He walked two, struck out seven on 130 pitches to help the Red Sox defeat the Royals 7-0. His no-hitter was also the first complete game of his career.
Lester re-signs with Boston
Lester agreed to a five-year contract extension with the Red Sox worth $30 million on March 8, 2009.
World champion once again
Lester was a force for Boston in 2013. He finished the season with a 15-8 record and a 3.75 ERA and went 4-1 in the postseason. Lester was 2-0 with a 0.59 ERA in two World Series starts against the St. Louis Cardinals, helping Boston win its second championship in seven years and third in the last decade.
Traded to Oakland
The A's acquired Lester on July 31, 2014 -- hours before the non-waiver trade deadline -- in addition to ex-Athletic Jonny Gomes for All-Star outfielder Yoenis Cespedes.
Debut with A's
Lester made his debut with the A's in Oakland against the Kansas City Royals on Yoenis Cespedes t-shirt giveaway day -- Aug. 2, 2014. He pitched 6.2 innings, gave up three earned runs on nine hits, and struck out three hitters. Lester recorded his 11th win of the season, and lowered his ERA to 2.59.
