Padres LHP Thatcher has arthroscopic surgery

San Diego Padres reliever Joe Thatcher has undergone exploratory

arthroscopic surgery on his strained left shoulder.

The left-hander is expected to begin a throwing program in six

weeks. He began the season on the disabled list. Manager Bud Black

said Thatcher could pitch this season if his rehab goes well.

Also, Triple-A shortstop Everth Cabrera, who was with the Padres

the last two seasons, broke the hamate bone in his right hand and

will be out six weeks.
