(AP) — Adam Wainwright has been diagnosed with an abdominal strain but the St. Louis ace could be available to pitch the Cardinals' opener at Wrigley Field on April 5. "[...] I feel good about what we know, and I know Adam is relieved," Mozeliak said. Wainwright went 20-9 with a 2.38 ERA last year, then underwent offseason elbow surgery to remove cartilage from his throwing elbow.
