Cards recall Grichuk as Robinson lands on DL

PITTSBURGH -- The Cardinals recalled outfielder Randal Grichuk on Tuesday while placing Shane Robinson on the 15-day disabled list with a left shoulder injury.

The roster move was expected after Robinson suffered a subluxation (partial joint dislocation) of his shoulder while sliding into second base in the ninth inning of Monday's 3-2 win over the Pirates. Robinson headed back to St. Louis for further examination, though manager Mike Matheny did not have an additional update as of Tuesday afternoon.

Grichuk gives the Cards a replacement outfielder on the roster and offers a right-handed power bat off the bench. Acquired by the organization in a trade with the Angels last November, Grichuk was hitting .259/.311/.493 with a team-high 25 homers in 108 games with Triple-A Memphis this season. He has a .325 batting average against left-handed pitching, and Matheny suggested that Grichuk could make periodic starts against left-handers.

Grichuk's primary role, however, will be as a bench player. That was the case on Tuesday, as Matheny summoned Grichuk in the seventh inning with runners on and the Cardinals trailing, 2-1. Grichuk responded with a game-tying RBI single in the Cards' eventual 5-2 loss to the Pirates.

"I'm just trying to go up there and be confident and aggressive," said Grichuk. "It got the job done. It's good for the confidence, and hopefully I can roll into tomorrow and get another one."

"We haven't seen him really dialed in," Matheny said before the game. "We have watched a lot of these players that we're getting from Triple-A that are having huge years, and it hasn't necessarily just clicked and translated here. We need it to. ... Randal has to prove to people that he can do it at this level. That's kind of the progression all the way through. He's done what he's needed to do at that level. Now he needs to make it work here."

Grichuk went 6-for-44 with one home run and three RBIs over 19 games with the Cardinals earlier this season. He comes back to the Majors intending to maintain the aggressive approach that helped him thrive in Memphis.

"I felt like I was a little bit too patient," Grichuk said of his earlier time in St. Louis. "I wasn't the aggressive hitter that I normally am. I feel like I let too many first and second strikes go by, and then I felt like I was playing catch-up and had to chase a few times. Hopefully this time, I can be in control of the count and swing at my pitches earlier in the count."

Grichuk was already on the list of the players the Cardinals intended to call up when rosters expand on Sept. 1. He gives the club added versatility with his ability to play all three outfield positions.

Seven Cards prospects headed for Fall League

PITTSBURGH -- Four players listed on MLB.com's Top 20 Cardinals prospect list will represent the organization on the Peoria Javelinas Arizona Fall League club, which will begin play on Oct. 7.

Outfielder Charlie Tilson (No. 7), right-hander Sam Tuivailala (No. 13), right-hander Tyrell Jenkins (No. 14) and infielder Jacob Wilson (No. 19) headline the group of participating prospects. The Cardinals are also sending right-hander Mitch Harris, right-hander Chris Perry and catcher Cody Stanley to the distinguished Fall League.

Five of those players are currently with the Cardinals' Double-A affiliate in Springfield, while Jenkins and Perry are pitching for the Class A Advanced team in Palm Beach. Jenkins will use the AFL experience to accrue innings lost in his shortened season. He made his season debut on June 17 after spending 10 months recovering from shoulder surgery.

Tilson, who was recently named to the Florida State League postseason All-Star team, has already played in a career-high 118 games while hitting .287/.333/.389 combined at two levels. Wilson currently leads that Springfield club with a .305 average, while Stanley has hit .295/.350/.445 with 12 homers and 42 RBIs in 96 Double-A games.

Harris has the most unique back story of any of the seven players, as he is wrapping up his second year of professional ball despite being taken by the Cardinals in the 13th round of the 2008 First-Year Player Draft. Harris had to put his career on hold while first serving five years in the military, during which he rose to the rank of lieutenant. He received his release from the Navy in January 2013 and has already risen to Double-A.

Harris, 28, has pitched in 39 games (Class A Advanced and Double-A combined) and posted a 4.22 ERA and 1.16 WHIP while allowing an opponents' batting average of .221.

The Cardinals will also be represented in the AFL by Jason Simontacchi, who will serve as the Peoria pitching coach. The Javelinas draw Minor League players from the Cardinals, Braves, Indians, Rays and Royals organizations.

Worth noting

• Yadier Molina went through an extensive workout at the organization's Double-A facility in Springfield, Mo., on Tuesday and is scheduled to begin a rehab assignment there on Wednesday barring any setbacks.

Manager Mike Matheny suggested that Molina will catch (not serve as the designated hitter) immediately upon starting game play. Molina has been on the disabled list since July 10 with a right thumb injury.

• Triple-A Memphis took a one-game lead in its Pacific Coast League division race with a 1-0 win over Fresno on Monday. Zach Petrick, making the start after scheduled starter Tyler Lyons was recalled to St. Louis, threw five innings and struck out seven. He allowed one hit. Kevin Siegrist and Eric Fornataro each pitched two scoreless innings behind Petrick.

• Tilson was named to the Florida State League's postseason All-Star team on Tuesday as a recognition for his standout season with Palm Beach. Tilson, a second-round selection in the 2011 First-Year Player Draft, hit .308/.357/.414 with 21 extra-base hits, 36 RBIs and 54 runs scored in 89 games for Palm Beach before being promoted to Double-A in mid-July.

• The Gulf Coast League Cardinals clinched the East Division title on Tuesday with walk-off victory over the Mets' Rookie-league affiliate. Magneuris Sierra followed a two-out triple with the game-winning single to lift the GCL Cardinals to a 2-1 win.
