Meyer probably should have been up, at least to get his feet wet, in 2014. As you state, he had a good season starting for Rochester, he needed to be added to the 40-man after the season anyway, and even if they wanted to shut him down and cap his innings around September 1st, we were effectively out of the race by the beginning of July yet proceed to waste a lot of innings in July and August on Correia, Pino, Deduno, Swarzak, Burton, and Kris Johnson, all of whom were gone from the organization for zero return by November. In 2015, Meyer probably should have tried starting again in the season's second half, after it was determined he wasn't going to help the 2015 Twins bullpen, just to get more opportunities/innings.
