I bought one of the Giants mystery bags at the game and inside was a signed ball. Well I can't read the sig and I don't recognize it. I'm hoping someone here will be able to tell me or help out.

Here's a pic of the ball, sorry if its a bit low quality:

SAN FRANCISCO -- It was not unexpected, but Giants catcher Mike Matheny announced his retirement Thursday, ending a 13-year Major League career due to post-concussion syndrome.
The four-time Gold Glove winner has had lingering dizziness and minor speech and memory issues since being beaned by a foul tip against Florida last May 31, and the 36-year-old veteran said symptoms increased with exertion.

Doctors advised him to discontinue playing, and in December the Giants hired catcher Bengie Molina as a replacement.

Rest here: Concussions end Matheny's career

I feel bad that his career had to end this way. I wish him the best of luck in whatever he chooses to do in the future.

I still cringe everytime he comes up to bat, but he did pretty well this past week and I'm happy for him.
