Timothy Howard Worrell (born July 5, 1967) is a former right-handed relief pitcher in Major League Baseball. During his fourteen-year Major League career, Worrell has pitched for nine teams, including the San Diego Padres, Cleveland Indians, Detroit Tigers, Oakland Athletics, Baltimore Orioles, Chicago Cubs, San Francisco Giants (twice), Philadelphia Phillies, and Arizona Diamondbacks.
Worrell's greatest success came in 2003 when he replaced the injured Robb Nen as the closer for San Francisco. After the season Worrell signed with the Philadelphia Phillies, where he returned to his previous role as a set-up pitcher, often pitching the eighth inning before Phillies closer Billy Wagner entered the game.
Worrell is the younger brother of former Major League pitcher Todd Worrell, himself a former closer for the St. Louis Cardinals and Los Angeles Dodgers.
On May 6, 2005, Worrell stated that he was dealing with "personal psychological issues" that had to be resolved and was subsequently placed on the 15-day disabled list. Prior to this disclosure Worrell had struggled, posting a 9.82 ERA, by far the worst of his career. Seemingly back to his old self, Worrell returned to pitch a perfect ninth on July 4, 2005 and completed the season in Arizona with an exceptional 0.90 ERA over his last 18 games.
On December 1, 2005, Worrell's return to the San Francisco Giants was agreed, with a two-year contract valued at $4 million.
On January 10, 2007 he announced his retirement due to a persistent nerve problem in his neck. Worrell did state that his major league career is not completely over as he wants to get into coaching. He is currently the rehab pitching coach for the Peoria Padres.
