Drew Patrick Storen (born August 11, 1987) is an American former professional baseball relief pitcher.

He played in Major League Baseball (MLB) for the Washington Nationals, Toronto Blue Jays, Seattle Mariners, and Cincinnati Reds.

He participated in the 2007 Indiana North-South All-Star Game, and was a state nominee for the 2006 Wendy's High School Heisman Award.

[6] Storen made an early and strong impact during his time with the Suns, and on July 19 he was called up to the Advanced-A Potomac Nationals of the Carolina League.

[8] Overall, Storen posted a 1.80 ERA in seven games with Potomac to earn a promotion to the Double-A Harrisburg Senators of the Eastern League.

[9] Storen started the 2010 season at Double-A and by the end of April was promoted to the Triple-A Syracuse Chiefs[10] after seven appearances in which he pitched 91⁄3 innings, allowing only one run, striking out 11 and walking one, earning four saves.

[9] He lasted at Syracuse just three weeks, in which he made six appearances allowing just one earned run before getting promoted to the Nationals on May 16.

[9][5] Storen made his major league debut on May 17, 2010, against the St. Louis Cardinals, retiring two batters in ⅔ of an inning.

[16] Tyler Clippard remained the Nationals' closer after Storen's return,[17] though they shared the role later in the season.

[25][26] Storen returned to the Nationals in July and finished the season strong, with scoreless outings in 18 of his final 21 appearances.

[1] In Game 2 of the 2014 NLDS against the Giants, Storen was brought in by manager Matt Williams in relief of starter Jordan Zimmermann, who had allowed three hits and no runs in the game and had retired the last 20 hitters he faced before walking second baseman Joe Panik with two outs the ninth.

Storen allowed two hits, a single to Buster Posey and an RBI double by Pablo Sandoval.

[27] Storen relinquished his closer role when Jonathan Papelbon was acquired by the Nationals from Philadelphia just before the trade deadline.

He struggled as the Nationals' setup man, ending with two disastrous outings against the New York Mets in early September.

After giving up the go-ahead runs on a homer by Yoenis Céspedes, Storen slammed a locker in frustration, breaking his thumb and ending his season.

[28] On January 8, 2016, Storen was traded to the Toronto Blue Jays in exchange for outfielder Ben Revere and a player to be named later.
