Career

Toronto Blue Jays

Lyon made his major league debut halfway through the 2001 season, posting a five-win, four-loss record for the Toronto Blue Jays, with a 4.29 ERA from 11 starts. He was the second youngest winning pitcher in Blue Jays' history after winning on debut (2-1 over Baltimore).

2002, however, was a different story. Lyon started the season as a starter for the Jays, but lost three of his first four decisions of the season, including a career-high 7 earned runs against the Yankees on April 10, and against the Angels on May 3. Three weeks later, Lyon was kicked from the rotation, and placed in the bullpen. He made his debut in this role at the SkyDome, against Boston, pitching 31⁄₃ innings. In five games of relief, Lyon had no decisions against him with a 5.19 ERA.

Boston Red Sox

During the postseason, the Red Sox claimed Lyon off waivers.

Boston made Lyon a permanent reliever, and Lyon appeared in 49 games in 2003, converting 9 saves in 12 opportunities with 50 strikeouts in 59 innings pitched. Lyon missed the entire 2004 season due to injury, after having been traded along with Casey Fossum, Michael Goss and Jorge de la Rosa to Arizona in exchange for Curt Schilling.

Arizona Diamondbacks

Lyon improved in 2005, converting 14 saves in 15 opportunities while pitching in 32 games and spending part of the season as the Diamondbacks' closer, replacing the injured José Valverde. However, he spent most of the second half on the disabled list. In 2006, Lyon had a very solid season, posting a 2-4 record and a 3.89 ERA in 68 appearances. In 2007, Lyon had probably his best season yet, with a 6-4 record, 2 saves, and the best ERA of his career, at a sparkling 2.68 in 73 games. Lyon found his niche as the Diamondbacks' primary setup man, pitching in front of Valverde, as Arizona won the NL West division title. For most of 2008, Lyon served as the closer for the Diamondbacks following the offseason trade of Valverde to the Houston Astros. However, he lost the job to Chad Qualls following second-half struggles.

Detroit Tigers

On January 24, 2009, the Detroit Tigers signed Lyon to a one-year contract. Lyon's Tiger season started off horrendously: Lyon compiled an ERA of 4.91 in April and a whopping 8.10 in May. From June on, Lyon redeemed himself somewhat by compiling a 1.56 ERA in 572⁄₃ innings. Lyon was used as a set-up man for Tigers closer Fernando Rodney. On November 10, 2009 Lyon filed for free agency.

Houston Astros

On December 12, 2009 Lyon signed with the Houston Astros to a 3-year deal, worth $15 million.

Return to the Toronto Blue Jays

Lyon was traded to the Blue Jays on July 20, 2012, along with J. A. Happ, and David Carpenter, for Francisco Cordero, Ben Francisco, Asher Wojciechowski, David Rollins, Joe Musgrove, and Carlos Pérez.

New York Mets

On February 7, 2013, it was announced that the New York Mets and Lyon had reached an agreement on a one-year contract, which became official on February 8. Lyon was designated for assignment on July 4, 2013. On July 9, Lyon was released.

Return to the Boston Red Sox

On July 19, 2013, The Boston Red Sox and Lyon had reached an agreement to a minor league contract. He was granted his release when informed he would not make the big league club.

Los Angeles Angels of Anaheim

On February 10, 2014, Lyon signed a minor league contract with the Los Angeles of Anaheim. On May 20, 2014, Lyon elected free agency after spending all season in Triple-A.

Pitching style

Lyon survives on five pitches: a four-seam fastball at 90-92 mph, a two-seamer at 90-91, a cutter at 89-91, and a curveball at 78-80. Occasionally, he also throws a changeup to left-handed hitters (85-87). Lyon's most commonly thrown pitch to right-handed hitters (and overall) is the cutter, while his lead pitch against lefties is the two-seamer. The curve is his most common 2-strike pitch.
