"It all depends on how I feel with time," Wong said. "I think [the shot] is helping, because my shoulder feels a lot better than it did yesterday. The pain is not anywhere close to what it was. I think taking a day or two off is really going to help get my shoulder back to where it needs to be."
Wong had three at-bats in Thursday's loss before being replaced at second base by Daniel Descalso, who also started there Friday. The sore shoulder forced Wong to let go of the bat with his top hand in his early-inning swings. Then, when he tried to finish his normal follow-through, the pain became too much, and he alerted the Cardinals' staff to the continued discomfort.
"I got a little stubborn in my last at-bat and wanted to do something," Wong said. "I tried to swing regular, and that's when I felt it. I knew I didn't want to push it and make it any worse."
Manager Mike Matheny did not rule Wong entirely unavailable (even as a pinch-hitter) for Friday night's series opener against the Blue Jays, though the preference would be to stay away from him. The Cardinals also did not see it necessary to have Wong have additional tests on Friday because he showed no decrease in range of motion.
With the expectation that this would be a short-term absence for Wong, the Cardinals would prefer not to place him on the disabled list, which would sideline him for a minimum 15 days.
"Once again, he's measuring out in strength, and the doctors who have looked at him don't believe there is anything structurally there," Matheny said. "It's just sore. When the soreness is keeping him from being able to do what he needs to do, that's when we need to back off. I don't think anybody is worried about him further injuring it."
