SEATTLE — The Seattle Mariners shipped right-handed starter Doug Fister and righty reliever David Pauley to the Detroit Tigers on Saturday morning for outfielder Casper Wells, infielder Francisco Martinez, left-hander Charlie Furbush and a player to be named later.

SEATTLE — The Seattle Mariners shipped right-handed starter Doug Fister and righty reliever David Pauley to the Detroit Tigers on Saturday morning for outfielder Casper Wells, infielder Francisco Martinez, left-hander Charlie Furbush and a player to be named later.

Fister is just 3-12 this season but it's a misleading statistic as he's received no run support all season from Seattle's anemic offense. Fister has the lowest run support of any pitcher in the American League at just 1.97 runs per game and has lost his last seven decisions spanning 10 starts.

Furbush and Wells will join Seattle's 25-man roster and be active for today's game against the Rays. Martinez will be assigned to Double-A Jackson.

The gem of the deal for Seattle might be Martinez, rated as one of the top prospects in the Tigers organization.

Orioles-Pirates Trade

Baltimore first baseman Derrek Lee has been traded to the Pittsburgh Pirates.

In return, the Orioles will get first baseman Aaron Baker.

Lee has come on of late. He is batting .246 with 12 homers and 41 RBIs this season.
