Mariners shortstop Jack Wilson put on DL

SEATTLE -- The Mariners made several changes on Monday not related to the dismissal of manager Don Wakamatsu and three coaches.

Shortstop Jack Wilson was placed on the 15-day disabled list with a fracture right hand sustained in a freak accident at home, and was replaced on the 25-man roster by infielder Chris Woodward. Also, right-handed pitcher Shawn Kelley returned from a rehab assignment at Triple-A Tacoma.

Wilson, who has been playing superbly, fractured the fifth metacarpal on his right hand early Sunday morning. He was batting .249 overall but 5-for-16 during the current homestand.

This is his second stint on the DL, the first time from May 6-June 22 with a right hamstring strain.

Wilson will have surgery on Wednesday in Seattle and be sidelined for up to six weeks.

Kelley, sidelined with a sore right elbow, is awaiting word on whether he will need a second ligament replacement surgery.

Woodward, 34, was batting .232 with 17 doubles, six home runs and 35 RBIs in 103 games with Tacoma.

Save chances few, but Aardsma on roll

SEATTLE -- The save opportunities have been few and far between the past couple of months for Mariners closer David Aardsma.

But he has been pitching a lot like he did last season when he registered 38 saves in his first season as a closer.

He has surrendered just one earned run -- a home run on Sunday -- in his past nine outings and is 4-for-4 in save chances since July 11. During the stretch, he has held opposing hitters to a .071 batting average (2-for-28) and struck out 11.
