The St. Louis Cardinals have not had a great deal of success in acquiring left-handed relievers that can consistently get the job done. From Marc Rzepczynski to Brett Cecil, the Cardinals have been in a position where they can’t trust their left-handed pitchers out of the bullpen for too long, and the front office is keen on changing that.
Despite not putting up the jaw dropping numbers that he did in his 2016 season, where he finished 4th in Cy Young Award voting as a reliever, Zach Britton still has been one of the best left handed relievers in the league for several years.
