The St. Louis Cardinals have a need for a starting pitcher and they will likely look to Nick Wittgren to fill that role. Wittgren has pitched well this season, with a 4.72 ERA, a 1.21 WHIP, and 57.13 K-BB ratio. His 2.-7 record is an improvement over last year, but there is no guarantee that he will stay on the team for the rest of the season.
