The Cardinals have activated righty Michael Wacha today, MLB.com’s Jenifer Langosch tweets. While that represents a welcome return, he will not slot into his accustomed spot in the rotation. After missing over a month with shoulder issues, there simply isn’t time for him to build up to a full workload. When Wacha moves into the pen, he may soon find company from another starting stalwart. According to ESPN.com’s Mark Saxon, St. Louis is still undecided whether to allow Jaime Garcia to take the ball when he is next scheduled. The 30-year-old lefty has struggled to a 4.65 ERA over 164 2/3 innings on the year, and has been hit hard particularly of late. Instead, the Cards may turn to young righty Alex Reyes, who continues to impress in multiple roles. - See more at: http://www.mlbtraderumors.com/2016/...ha-for-pen-duty-weighing-rotation-change.html
