Dallas Braden, the former A’s left-hander who pitched the 19th perfect game in major-league history, told me today that he is retiring after failing to come back from multiple shoulder surgeries.

“There is nothing left in there, it’s just a shredded mess,” Braden said by phone. “I left my arm on the mound at the Coliseum, and I’m OK with that.”

Braden, 30, is from Stockton and he went 26-36 in five seasons with Oakland, but he will be best remembered for his Mothers Day perfect game at the Coliseum against Tampa Bay in 2010. Braden, who as a teenager had lost his mother, Jodie Atwood, to cancer, was able to celebrate his achievement on the field with his beloved grandmother, Peggy Lindsey.

“That game will always define the one solid day of work I had and the fact that I got to share it with my grandmother, only a few people appreciate the magnitude of that,” Braden said. “That was living the dream.”

Braden has few regrets about his injury-shortened career, and he bears no ill will toward the A’s; one of the team’s former doctors severed a nerve in Braden’s left foot in 2009, leading to a lawsuit.

“The A’s are the ones who gave me the opportunity, and there was no better place for me to be,” said Braden, who declined to speak further about the lawsuit other than to say, “It’s all taken care of.”

Braden had been throwing all winter and was preparing to hold a showcase for teams this month, but after another recent setback, he had an MRI that showed too much damage to repair.

“I wasn’t in a position to repeat my delivery, to pitch with any intention,” he said. “That’s OK, I understood the odds I was facing. You have to face your mortality one day, and I have been so blessed in this game. If I take 10 minutes to be hacked off about it, it would be nine minutes too long. You can’t ask for more than I’ve been given, coming where my grandmother and I are coming from.”

Braden, said he would like to stay in the game as a broadcaster or as a coach; he went to auditions for the Fox network this week. He is now living in Los Angeles and engaged to be married to actress Megan Barrick in November.

In other A’s notes, in case you missed my tweet the other day, the team is definitely not pursuing Mashiro Tanaka.
