Seldom is a competition on purely equal footing. This is a case in point. May and Meyer are both 24-yo RH pitchers acquired for Twins' center fielders. Yet, there are differences that make May's promotion the easy call and delay Meyer, possibly until next year. 1) Meyer has been on a pitch and innings limit. The boundaries aren't exact, but Meyer will likely be shut down while May should be good to go through September. 2) Meyer is not on the 40-man roster and the 40-man is full. While the loss would only be something like Pedro Florimon, the Twins are reluctant to add Meyer this late in the year and perhaps burn an option on him, as well. I'd love to see the 6'9" kid pitch for the Twins this year, but I'm happy that May will be getting his shot, with Milone waiting in the wings.
