ST. LOUIS -- Outfielder Shane Robinson will rejoin the Cardinals on Sunday, taking a roster spot that opened upon the Cardinals' need to place second baseman Kolten Wong on the disabled list.
Wong continues to be bothered by his left shoulder, which he jammed while making a diving play on June 3. Shoulder soreness forced him out of the game two days later, after which Wong rested for four days while the Cardinals made a trip to Toronto. Upon returning, he was 2-for-26.
"I think they go hand in hand," manager Mike Matheny said of Wong's shoulder and struggles. "He's really trying to grind though, but since that happened, you've been able to see that he hasn't been able to get a good finish on the swing. We're going to make the move."
By placing Wong on the 15-day DL on Saturday, the Cardinals will be able to activate the rookie second baseman as early as July 6. Matheny suggested that the club's medical staff will do some more advanced testing and treatment on the area now that the Cardinals know Wong will be unavailable for at least two weeks.
With Wong sidelined, Mark Ellis is expected to get the bulk of playing time at second. He went 1-for-3 in Saturday's win.
Robinson, who has vacillated between Memphis and St. Louis this season, gets the summons from Triple-A, where he hit .274/.375/.339 with 11 runs in 16 games during this most recent stint. Matheny said that the flexibility offered by infielders Daniel Descalso and Ellis allowed for the Cardinals to call up an outfielder instead of an infielder.
