SAN FRANCISCO -- Matt Holliday engaged in a full workout Friday morning, his first since undergoing an appendectomy on April 1, and hopes to return to game action during the Cardinals' weekend series against the Giants.

"I don't think that's a stretch," Holliday said. "I think Sunday's definitely a possibility, and possibly even tomorrow depending on [how things go]. I can't say without talking to Greg [Hauck, the Cardinals' head athletic trainer], but in my mind, that's definitely a possibility."

Manager Tony La Russa seemed less sanguine about Holliday's chances of playing in San Francisco, but didn't rule it out.

"I think that's probably really a push," La Russa said. "I'm not saying he wouldn't, because he was in such great shape when he got hurt and we're anxious to get him back, but that seems like a push. But if they give him the green light and he says he's ready to go ..."

La Russa did say he fully expects Holliday to play before the end of the Cardinals' current road trip, which runs through April 17, but that's not exactly news. If the club didn't expect Holliday to play sooner than that, he would have been placed on the 15-day disabled list.

Greene gets first start of season

SAN FRANCISCO -- Tyler Greene had to wait more than a week for his first start of the season, but it might only be two days before his second.

Greene got the call at second base Friday against Giants left-hander Jonathan Sanchez. He could start again Sunday against Barry Zito, either at second base, or at shortstop or in center field if manager Tony La Russa wanted to give another of his everyday players a day off. Greene is a shortstop by trade but has worked at various positions.

"It's not the same as the left side [of the infield]," Greene said of playing second base, "but it's as comfortable as it can be. I've got the timing of things down a little bit better."

Plane trip turns alarming for eight Cardinals

SAN FRANCISCO -- A group of eight Cardinals players and staff got a significant scare Thursday when their private plane had a loss of cabin pressure, necessitating a return to St. Louis just a few minutes into their flight to the West Coast.

Manager Tony La Russa, coaches Joe Pettini and Jose Oquendo, assistant athletic trainer Barry Weinberg and pitchers Kyle Lohse, Ryan Franklin, Mitchell Boggs and Trever Miller were scheduled to fly to the San Francisco Bay Area early Thursday in order to participate in a benefit golf tournament. However, the plane encountered a problem shortly after takeoff and returned to St. Louis, so none of the eight attended the event. The tournament, a benefit for La Russa's Animal Rescue Foundation, went on without the cadre of Cardinals.

"They said it turned out better because we didn't play," La Russa quipped.

All eight men instead traveled to San Francisco on the Cardinals' team charter, which departed Thursday afternoon.

Baby Birds update

• Triple-A Memphis opened its season with an 8-7 defeat at home against Oklahoma City on Thursday. Shane Robinson went 5-for-6 with three RBIs, but P.J. Walters was touched for five runs in four innings.

• Double-A Springfield fell to Frisco, 6-2, despite a double and a home run from Alex Castellanos.

• Shelby Miller pitched five dominant innings for Class A Palm Beach but took the loss in a 1-0 defeat to St. Lucie. Miller allowed an unearned run on four hits, struck out nine and walked one. Zack Cox was 2-for-4 with a double.

• Class A Quad Cities was rained out against Beloit.

Player of the day honors go to Miller, who did all that could be asked of him in his Palm Beach debut. The only run against Miller came courtesy of two singles, a catcher's interference call and an infield groundout. He had only one out in the air, and that was a popup to first base.

Tidbits

• Saturday night's Cardinals-Giants game has been rescheduled for 9:05 p.m. CT, an hour later than originally announced. Giants players will receive their World Series rings prior to the game.

• The Cardinals will stay on rotation for their upcoming series in Arizona. Rather than moving Chris Carpenter up to his fifth day, the Cardinals will start Kyle McClellan on five days' rest Monday, followed by Carpenter on five days' rest Tuesday. Jake Westbrook will start the series finale Wednesday against the D-backs.

• Manager Tony La Russa said that David Freese could play all three games of this weekend's series in San Francisco. Freese started Friday and will play Sunday. The question is Saturday night. If Freese doesn't start that game, Daniel Descalso will play third base.
