SEATTLE -- The Seattle Mariners traded pitchers Doug Fister and David Pauley to the Detroit Tigers on Saturday.
In return, the Mariners acquired pitcher Charlie Furbush, outfielder Casper Wells, third baseman Francisco Martinez and a player to be named later.
Fister, 27, made 21 starts for the Mariners this season, compiling a respectable 3.33 earned run average. However, the towering right-hander ranks last in the American League in run support average (1.97 runs) which helps explain his 3-12 record. He has not won since May 30, losing his last seven decisions.
The 28-year-old Pauley went 5-4 with a 2.15 ERA in 39 relief appearances for Seattle this year.
"Doug and David have done a very nice job for us, and it was tough for us to move them, but as we continue to accumulate talent in our organization that will allow us to be the kind of team we aspire to be, a team that contends for and wins championships, these are the sort of tough decisions we need to make when the opportunity presents itself," said Mariners general manager Jack Zduriencik.
Furbush made his major league debut in May. The 25-year-old left-hander is 1-3 with a 3.62 ERA in 17 games, including two starts, for Detroit this season.
Wells, 26, appeared in 64 games with the Tigers this year before being optioned to Triple-A Toledo on July 20. In those contests, Wells batted .257 with four home runs and 12 RBI.
The 20-year-old Martinez was hitting .282 with seven home runs and 46 RBI in 91 games with Double-A Erie. He will report to Seattle's Double-A affiliate, the Jackson Generals in the Southern League.
The Mariners also recalled pitcher Dan Cortes from Triple-A Tacoma and optioned pitcher Aaron Laffey to the Rainiers.
