That may have been true with the other players you mentioned, but I'm not sure that would have been true with Mclean. I read an article a few weeks ago about how he has changed his pitch mix this year. He has four pitches, but it wasn't until he developed command of the sweeper that he was ready for the majors. That has become his most effective "out" pitch, he now throws it (IIRC) 40 % of the time and it has made his other pitches more effective. If they had brought him up earlier, I'm not sure if he would be pitching like we've seen. Later
