Kyle Lynn Farnsworth (born April 14, 1976) is an American former professional baseball pitcher and part-time bodybuilder.

He played for the Chicago Cubs (1999–2004), Detroit Tigers (2005, 2008), Atlanta Braves (2005, 2010), New York Yankees (2006–2008), Kansas City Royals (2009–2010), Tampa Bay Rays (2011–2013), Pittsburgh Pirates (2013), New York Mets (2014), Houston Astros (2014) in Major League Baseball, and for the Pericos de Puebla (2015) and the Broncos de Reynosa (2016) of the Mexican League.

Reds pitcher Paul Wilson stepped out of the batter's box after an inside pitch, and started to yell at Farnsworth.

[5] In the 2004 season, Farnsworth angrily kicked an electric fan in the Cubs' dugout after an outing in which he gave up six runs in one inning to the Houston Astros.

Farnsworth ended up severely bruising and spraining his knee in the process, and was placed on the disabled list as a result.

[6] On February 9, 2005, he was traded to the Detroit Tigers for Roberto Novoa, Scott Moore and Bo Flowers.

[7] Farnsworth was involved in a bench-clearing fight in the 2005 season while playing for the Detroit Tigers, against the Kansas City Royals at Comerica Park.

[9] Following the season, Farnsworth signed with the New York Yankees, replacing Tom Gordon as the team's primary set-up man.

[13] On June 17, 2009, Farnsworth's left, non-pitching hand was bitten while he was breaking up a fight between two of his American bulldogs—Strike and Rambo.

Farnsworth later taped his finger, tucked it into his glove, and went to practice telling manager Trey Hillman that he could pitch.

"[14] On July 31, 2010, Farnsworth was re-acquired by the Braves along with Rick Ankiel for Gregor Blanco, Jesse Chavez and Tim Collins.

[16] For 2011 Farnsworth posted a record of 5-1 with 25 saves as Tampa Bay's closer and a career-low 2.18 ERA in 63 relief appearances.

[18] Unlike his first two years with the Rays, Farnsworth was ineffective in 2013, and was designated for assignment and then released in August 2013, just before another economic incentive would kick in.

[25] On April 20, Farnsworth was named the new Mets closer after another blown save by Parnell's replacement, José Valverde.

[27] Farnsworth earned his second save as Mets closer three days later on April 23, giving up a run on three hits but managing to hang on for a 3–2 win over the Cardinals.

However, after the game, Mets manager Terry Collins stated that Farnsworth was still the closer and that the Matsuzaka was the backup option.

[32] Farnsworth rebounded on May 12, getting his third save of the season in the opening game of the Subway Series against cross town rivals the New York Yankees.
