Adding clout to consistency, Buster Posey hit his first home run of the season Sunday in Triple-A Fresno's series finale at Reno.

Posey entered the game 7-for-13 after recording three consecutive multihit efforts.

Posey, the Giants' top prospect, continued his attempts to diversify himself by starting at first base, though he remains primarily a catcher.

Aurilia officially announces retirement

SAN FRANCISCO -- It has been obvious since the end of last season that Rich Aurilia's career as an active player was over. But the ex-infielder refrained from officially announcing his retirement until this weekend, as he attended the reunion of the Giants' 2000 National League West division championship team at AT&T Park.

Aurilia said Sunday that he has asked his agent, Barry Axelrod, to call Giants president Larry Baer on Monday "and basically tell him, 'Hey, I'm done.'"

Aurilia is expected to remain with the Giants in some capacity, perhaps as a part-time radio or television commentator. He already has provided commentary for Spring Training programming and last Friday when the Giants played their home opener.

Aurilia, 38, admitted that had mixed feelings about officially stepping aside as a player.

"It's weird being around here, man," Aurilia said. "I wanted to grab a bat in the 11th inning the other day when they had guys on third with less than two outs. I miss being around the guys and I miss the competition, but everything else I'm OK with. It's time for a different phase of my life. I'm actually handling it better than I thought I would, which is good."

Giants of 2000 lament playoffs

SAN FRANCISCO -- When the Giants or their fans ponder postseason near-misses, thoughts inevitably turn to the 1962 World Series, which ended with Willie McCovey's line drive to second base in Game 7 with runners on second and third, and the 2002 World Series, when the Giants squandered a 5-0 lead in Game 6 before losing Game 7.

A few of the 2000 Giants also felt cheated out of greater success, though that club didn't even make it out of the Division Series against the New York Mets. The Giants captured the series opener before New York won the next three games to eliminate them. The Mets ultimately advanced to the World Series.

Nevertheless, the Giants honored their 2000 club Sunday by staging a reunion in conjunction with the 10th anniversary of the opening of AT&T Park.

Left-hander Shawn Estes, who injured his left ankle in Game 2 against the Mets, still senses the frustration.

"That's the thing I think that stands out the most -- the disappointment I felt, that we felt, in New York [after] that last game," Estes said. "We felt like it should't have ended. We should have won. We were the hottest team coming into the postseason."

The Giants scored only two runs in 22 innings spanning two games at New York's Shea Stadium, which wasn't what they expected.

"I put that 2000 team as probably the best offensive team that I've played on, because of the guys that we had in the middle of the lineup in the prime of their careers," shortstop Rich Aurilia said. "We just didn't get it done in the postseason."
