Adams placed on disabled list with sore calf

ST. LOUIS -- The Cardinals proceeded cautiously with Matt Adams' sore left calf muscle, but when he had to be held out of the lineup for a third straight day Friday, there was no choice but to send him to the disabled list.

Adams first felt the tightness in the final innings of Tuesday's 6-0 win against the Yankees. He was held out of the lineup a night later, but pinch-hit.

In that at-bat, the tightness remained.

"I felt it that at-bat," Adams said. "It's just a thing where we thought it would be a couple of days, and it just didn't clear up."

Adams was held out of the lineup the next two games and was unavailable to pinch-hit. When general manager John Mozeliak went to the clubhouse prior to Friday's game, he was told by the team trainer that the injury was taking longer than expected to clear up and could last until Tuesday or later.

"He's still not improving to where he can push it," Mozeliak said. "Until he gets to that point, I didn't know when we were going to be able to play him. You can be patient with these things sometimes, but you can't go five days playing short."

The Cardinals placed Adams on the 15-day disabled list retroactive to May 29 and called up their top prospect, Oscar Taveras, to fill the void.

Taveras' promotion prompts contested center field

ST. LOUIS -- The Cardinals have run into a logjam in the outfield, creating uncertainty for what may happen with the lineup on any given day.

With the promotion of 21-year-old outfielder Oscar Taveras, who will likely get extensive playing time in the corner outfield positions, center field is a three-way race.

"I think center field is still a little bit in play, if you will," Cardinals general manager John Mozeliak said. "[Jon] Jay's hitting, so Jay deserves opportunities to continue to play."

Jay was hitting .293 in 47 games entering Saturday's game against San Francisco. He hit a bases-clearing double Saturday night and has hit .400 (10-for-25) in his last eight games.

There is also Randal Grichuk, a 22-year-old who hit .315 with a .589 slugging percentage and 10 homers at Triple-A before being recalled Friday. The Cardinals promoted the young outfielder with the idea that his playing time wouldn't suffer.

"We're going to continue to get looks in for Randal and see what we can see," Cardinals manager Mike Matheny said. "We don't want to waste how well he's done and the timing he's been kind of able to put together."

The odd-man out could be Peter Bourjos, whom the Cardinals acquired during the offseason. Bourjos has hit just .204 in 41 games this season.

"Right now, Bourjos is going to have to understand his role may be diminished a little bit and may be seen more as a defensive replacement late in the game," Mozeliak said.

For now, there is no plan for how the outfield rotation might work in the coming weeks. Jay got the start Saturday afternoon.

Worth noting

• With a single in the fourth inning against the Giants on Saturday, third baseman Matt Carpenter extended his hitting streak to 13 games, the longest active streak in the National League. Carpenter's career-high hitting streak is 18 games.

• The Cardinals' 9-4 loss to the Giants on Friday night sent them to their third straight defeat, marking their longest losing streak of the season. Entering Saturday, the Cardinals had lost four of five games on their current homestand.
