Mariners' George Kirby: Plays catch Friday

Kirby (shoulder) played catch with a trainer for a few minutes Friday, Shannon Drayer of SeattleSports.com reports.

It's not much, but it's the first time Kirby's done any throwing since he was diagnosed with right shoulder inflammation March 7. The right-hander is hoping to be ready for his season debut around mid-April, but a clear timeline for the right-hander has not yet been established.
