Three-time All-Star Matt Cain says Saturday start will be his finale

PHOENIX -- Matt Cain is set to make one final start before he calls it a career.

Cain talked to hisSan Francisco Giantsteammates in a closed clubhouse before Wednesday's game at Arizona, telling them he is ready to retire.

Before he goes, the right-hander, who threw the only perfect game in Giants history and helped them win two World Series titles, will pitch once more -- home at AT&T Park, on Saturday against the San Diego Padres. Beset by injuries in recent years, Cain will start a day before his 33rd birthday.

"This organization has meant so much to me. It's meant so much to my family. I'm just grateful it's been a part of my life. I've enjoyed it so much," Cain said.

"I think we've been through the full gamut of everything. That is something that is satisfying. I know I am able to hang my hat at the end of the day and say I put everything I could into this and I've experienced it all and enjoyed every bit of it," he said.

Cain has been slowed by elbow and hamstring trouble in recent years. The season, he's 3-11 with a 5.66 ERA in 26 games, 22 of them starts for the last-place Giants.

The three-time All-Star is nearing the end of his contract with the Giants, who have an option for one more season. He was a first-round draft pick by them in 2002 and made his big league debut in 2005.

"I've been able to be lucky enough to be with the same organization," Cain said. "It means so much to me, and I can't picture myself putting a different uniform on."

Cain has a career record of 104-118 with a 3.69 ERA. Despite the below-.500 mark, he'll leave with a lot of winning memories.

In 2010, Cain made three starts in the postseason, posting a 0.00 ERA in 21⅓ innings as the Giants won their first crown since 1954, when the club was based in New York.

In 2012, he threw a perfect game against Houston, striking out 14. Cain set a career high in wins that year, going 16-5.

That October, he won the deciding Game 5 of the National League Division Series against Cincinnati, then topped St. Louis in Game 7 of the NL Championship Series. He also started in Game 4 of the World Series against Detroit, with the Giants winning in the 10th inning to finish off a sweep.

"His play on the field and community service exemplifies what a true big leaguer should be and he will definitely be missed," Giants president and CEO Larry Baer said in a statement. "On behalf of the Giants, I congratulate Matt on an outstanding career and wish him and his family all the best. He'll forever be a Giant."

Giants manager Bruce Bochy said Cain, who was moved to the bullpen during the season, has meant a lot to the organization and is well respected among his teammates.

"He's never come in this office and complained one time. He just wants to do what was best for the club," Bochy said. "He had a nice little talk for the guys."

Before the bottom of the first inning on Wednesday, the crowd at Chase Field was informed of Cain's impending retirement in a public address announcement. He doffed his cap to the fans and the Diamondbacks' dugout in appreciation of the gesture.

"He didn't want to put on another uniform. That says a lot about him," Bochy said.
