Seattle Mariners Executive Vice President & General Manager Jack Zduriencik announced the club has acquired right-handed pitcher Chance Ruffin as the player to be named later in the July 30 trade with the Detroit Tigers. The Mariners acquired OF Casper Wells, LHP Charlie Furbush and INF Francisco Martinez from the Tigers in exchange for RHP Doug Fister and RHP David Pauley.

Ruffin (#52) will be available for tonight’s series finale against the Toronto Blue Jays at Safeco Field (7:10 p.m. PT). To make room on the Major League 25-man and 40-man roster, left-handed pitcher Aaron Laffey has designated for assignment. Seattle has 10 days to trade, release or outright the contract of Laffey.

Ruffin, 22 (turns 23 Sept. 8), has split his first professional season between AA Erie, AAA Toledo and made a pair of relief appearances with the Tigers (0-0, 4.91). He made his Major League debut July 25 at Chicago (AL). In 13 appearances with Toledo, the right-hander posted a 1.84 ERA (3 ER, 14.2 IP) and was 9-for-10 in save opportunities.

Ruffin was a supplemental first round pick (48th overall) in the 2010 June Draft out of the University of Texas. He made his pro debut with the Surprise Rafters in the Arizona Fall League, posting a 1-1 record with 4 saves and a 3.86 ERA (4 ER, 9.1 IP) in 10 relief appearances. He was tabbed by Baseball America as the Tigers 7th-best prospect and rated as having the best slider in the Tigers organization heading into the 2011 season.

In three seasons at the University of Texas, Ruffin went 24-6 with 19 saves and a 2.39 ERA (71 ER, 267.1 IP) in 85 games/28 starts. As a junior in 2010, he earned All-Big 12 Conference and Baseball America All-America honors, and was named the National Collegiate Baseball Writers Association Stopper of the Year. He led the nation in strikeouts per 9.0 innings (13.49) and ranked 2nd in ERA (1.11).

A native of Austin, TX, Ruffin is the son of former Major League pitcher Bruce Ruffin. Bruce pitched for 12 years in the Major Leagues with Philadelphia, Milwaukee and Colorado, posting a 60-82 record with 63 saves.

Laffey, 26, appeared in 36 games for the Mariners going 1-1 with a 4.01 ERA (19 ER, 42.2 IP). In his last appearance Tuesday night vs. Toronto he allowed 4 hits and 3 runs in 1.1 innings. Laffey was acquired from Cleveland in exchange for minor league infielder Matt Lawson on March 2, 2011.
