Carpenter thrilled for good friend Halladay

CHICAGO -- The only thing missing from a perfect day for Chris Carpenter on Saturday was a Cardinals win.

Carpenter attended the Stanley Cup Finals playoff game between the Chicago Blackhawks and Philadelphia Flyers, and as he sat in the stands, he received a text that good friend and former teammate Roy Halladay had a perfect game in the works in Miami.

"I got a text in the middle of the hockey game that he was close," Carpenter said. "So I watched the final two innings on my phone."

The two right-handers were teammates in Toronto, coming up together through the Blue Jays system. They've remained friends and mutual admirers. Still, Carpenter said he hasn't dialed up his old buddy just yet.

"I texted him," he said. "I figure he's got millions of people calling him. ... That's pretty special, though."

Cards could announce roster move Monday

CHICAGO -- Things have been so hectic for the Cardinals lately that it was news when they arrived at the park on Sunday with the same 25-man roster that left Wrigley Field on Saturday afternoon. However, that arrangement may only last one day.

St. Louis may send out a pitcher in favor of a position player as soon as Monday when it opens a six-game homestand with a matinee against the Reds. Manager Tony La Russa previously said it was a possibility that the club would make such a move prior to Sunday's game at Wrigley, but instead the transaction will wait.

"Maybe something for tomorrow," La Russa said. "We didn't feel like we had to do it today."

The Cardinals have a lot of moving parts on their pitching staff right now, with Kyle Lohse likely out for two months and Brad Penny's status uncertain. One factor in any decisions will be how quickly the club believes Penny can return from a right lat strain. In the immediate term, though, the question is balancing the bullpen with the need for bench help. St. Louis is currently playing with an eight-man bullpen and only four players on the bench.

One name that has come up is that of Aaron Miles, currently at Double-A Springfield. La Russa didn't dismiss the possibility of Miles being called to the Majors, but he certainly didn't encourage that line of thinking either.

"If you're in the organization, then you've got a shot to be in the conversation," he said.

Baby birds

Tyler Greene homered and Amaury Cazana drove in three runs, but it was a rough day for Triple-A Memphis pitchers in a 16-6 loss to Albuquerque on Saturday. ... Aaron Miles doubled, walked twice and drove in five runs, and Matt Carpenter went 3-for-5 in Double-A Springfield's 12-5 win against San Antonio. ... Mark Diapoules struck out five against one walk over six innings, and Alex Castellanos homered and drove in two runs, leading Class A Advanced Palm Beach to a 6-3 win over Lakeland. ... Shelby Miller lasted only 2 2/3 innings, but Justin Smith pitched 4 1/3 excellent innings in relief as Class A Quad Cities beat Burlington, 12-4. C.J. Beatty went 3-for-4 with three runs and a walk.

The torrid Carpenter is player of the day for his three-hit, three-RBI showing. The TCU product is hitting .362 with a .429 on-base percentage in 17 games since he was called up from Palm Beach to Springfield. The third baseman was drafted in the 13th round last year and has advanced extremely rapidly through the system.

Worth noting

Colby Rasmus received an off-day on Sunday, with Jon Jay getting the start in center. Rasmus is 3-for-19 with 11 strikeouts over his last seven games, though he has drawn six walks for a .360 on-base percentage in that span. ... The Cardinals will honor veterans prior to and during Monday's Memorial Day home game against the Reds. They will wear a special white-and-red cap with a stars-and-stripes pattern on the logo. Members of the armed forces will receive a complimentary ticket when they present a valid military ID at the Busch Stadium ticket windows. The club will recognize veterans in a pregame ceremony. ... Cardinals manager Tony La Russa did, in fact, attend Saturday night's Stanley Cup Finals game and was thrilled to find that he had center-ice seats.
