3 designated hitter possibilities for the St. Louis Cardinals

Kyle Schwarber
Kyle Schwarber became a free agent after declining a mutual option with the Boston Red Sox in November. Schwarber hits some massive home runs and will certainly be a name many call on to fill their need for a bat.
The Cardinals should definitely look into Schwarber.
In 113 games between the Washington Nationals and Boston Red Sox, Schwarber hit .266/.374/.552 with a +145 wRC and a .306 BABIP. He hit 32 home runs, 19 doubles, and 71 RBI. For his career, which includes about five and a half seasons with the Chicago Cubs, he’s hit 153 homers.
Yes, with much time spent with the rival Cubs, it would be weird to see him in a Cardinals uniform. Schwarber is definitely a bat you want and if he’s available, the Cardinals should take a shot at getting him.
