George Friederich Sherrill (born April 19, 1977) is an American former professional baseball relief pitcher.

Sherrill pitched in Major League Baseball (MLB) for the Seattle Mariners, Baltimore Orioles, Los Angeles Dodgers, and Atlanta Braves from 2004 through 2012.

In 2004, Sherrill started the season with the Tacoma Rainiers of the Class AAA Pacific Coast League (PCL), making the Triple-A All-Star team.

Sherrill made his MLB debut on July 16, 2004, against the Cleveland Indians, pitching one inning of relief and allowing two earned runs.

[6] With the 2006 injury of Mark Lowe, and the trade of Rafael Soriano during the offseason, Sherrill became the primary setup man for Mariners closer J. J. Putz.

[6] On July 30, 2009, Sherrill was traded to the Los Angeles Dodgers for two prospects: third baseman Josh Bell and pitcher Steve Johnson.

[6] Sherrill struggled in 2010 to the point where he was once put on outright waivers, though he refused a minor league assignment and remained on the Dodgers' roster the full season.

[18] After appearing in two games and giving up four runs, on Sherrill was placed on the 15-day disabled list with a strained flexor bundle in his left elbow.

[23] During the 2008 season, some of Sherrill's Baltimore teammates would flip up the brims of their hats every time he successfully closed out a game.

In a MASN post-game interview, Sherrill credited former Orioles first baseman Kevin Millar, a noted prankster, as the originator of this gesture.
