Martinez is now expected to make his next start Saturday against the Giants, Jenifer Langosch of MLB.com reports.
While Martinez was tentatively slated to start Friday's series opener against the Giants, it appears the Cardinals will award the start to Michael Wacha, who was skipped over last time through the rotation to allow him to get extra rest. This will likely just push Martinez's next start back by a day, still lining him up against the Giants. The 25-year-old currently owns a 3.88 ERA and 57:21 K:BB through 48.2 innings (eight starts) this season.
