SAN DIEGO -- Second baseman Kolten Wong, who has been bothered by back pain since Sunday, flew back to St. Louis on Tuesday to be examined by the Cardinals' medical staff.
Manager Mike Matheny offered optimism that "by Friday, [Wong] will be ready to go." That will depend not just on the results of Wong's medical exam, but also how quickly he can get his locked-up back to release.
Wong's departure necessitated the addition of another second baseman, which the Cardinals addressed by recalling Breyvic Valera. But losing Wong for any length of time will be a hit to the offense. Wong just finished August with a .347 batting average and has a .300/.383/.438 slash line on the season.
He has been sidelined by injury twice previously this season, first with a left elbow strain in late May and then with a right triceps strain a few weeks later.
The Cardinals don't expect injuries to Dexter Fowler (left hip) or Tommy Pham (right shoulder) to linger. Both were cleared to pinch-hit on Tuesday and could return to the lineup as early as Wednesday.
Fowler hasn't played since exiting Saturday's game after jarring his hip while legging out a triple. Pham was removed in the seventh inning on Monday after feeling what he described as "dead arm" during his final plate appearance.
