McGonigle was promoted to AA after a grand total of 14 games in A+ last year and 36 this year. He played 12 games in A ball and then 60 the next season before being promoted to A+. He will start next year in AAA. And if he performs how he will be expected and projected to at AAA, it won't take more than 50-60 games until he forces the Tigers hand to call him up.
Anybody who thinks Tigers are planning to have him spend the majority of season in AAA, let alone mention AA lol, is kidding themselves. Nothing Harris has said or done should be interpreted to suggest the Tigers think McGonigle needs a lot of seasoning or reps at any level where he proves he's too good.
