CINCINNATI -- For the second time this season, Lance Berkman's return from the disabled list has squeezed outfielder Shane Robinson out of a roster spot.

Robinson was optioned to Triple-A Memphis prior to Saturday's game in order to free up room for Berkman's addition onto the 25-man roster. Robinson endured the same fate two months ago when Berkman came back from a left calf strain.

In that instance, Robinson was hardly gone for 48 hours before an injury to Jon Jay prompted his return.

"I think [Robinson] was kind of expecting it," said Cardinals manager Mike Matheny, who, along with general manager John Mozeliak, informed Robinson of the roster move after Friday's game.

"We sat in here and talked about all the good things that he's done. He's put together some good pinch-hit at-bats for us and played a very solid outfield for us. We gave him a couple small things to work on and told him to go get swings in."

Though the Cardinals lose a center fielder in the roster switch, the club has ample protection behind starter Jon Jay. Skip Schumaker can fill in there, as can Carlos Beltran. The Cardinals are also not as concerned about having a right-handed-hitting center fielder to complement Jay, since Jay has shown an ability to hit both righties and lefties this season.

Robinson, who had a pinch-hit RBI single on Friday, hit .256 in 125 at-bats with the Cardinals this season. He started 25 games and went 7-for-29 (.241) as a pinch-hitter.

Worth noting

• Matt Holliday enters Saturday riding a 12-game hitting streak, the longest such streak by a Cardinals player this season. It is the third longest active streak in the National League, and Holliday has hit .400 during the 12-game span. Since May 1, Holliday has pulled his batting average up from .215 to .315.

• The Brewers have set their rotation for their upcoming series against the Cardinals at Miller Park. St. Louis will face Mike Fiers (3-3, 2.31 ERA) on Monday, followed by Randy Wolf (2-6, 5.80) on Tuesday and Zack Greinke (9-3, 3.32 ERA) on Wednesday. This will be the Cardinals' second and final trip to Milwaukee this season.

• Left-hander Tyler Lyons tossed seven scoreless innings in Triple-A Memphis' 5-0 win over Round Rock (Tex.) on Friday. Lyons allowed three hits and two walks, while striking out four. The win was Lyons' first in six starts since being promoted from Double-A.
