Reyes the 21-year old (22nd birthday in less than 2 weeks) has sported strikeout rates above one per inning all through the minors. They've moved him up rapidly, but nothing super-aggressive given his success. The one lesson, maybe, is at AAA his ERA ain't all that good (PCL tends to run hot), yet they deemed him ready and brought him up. Weaver the 22-year old (23rd birthday next week - detect a pattern?) likewise had mostly 9+ K/9 rates except for an anomalous high-A stint. They've let him basically skip AAA, so this will be very interesting to watch play out. Tuivailala the 23-year old (October baby) has taken slightly longer to reach the majors, also being a strikeout per inning guy essentially every year. He shares with Reyes some mediocre AAA numbers and a call-up to the majors anyway. He's back at AAA now. Mayers the gray-beard 24-year old (December) has less of a K/9 pedigree and this probably explains why it took him this "long" to get a call-up. He's back in AAA too. There's probably something to be learned from their promotion policy for pitching prospects, but more to be learned about getting the performance out of them, or picking wisely. Or maybe if our guys had to pitch in Reno and Salt Lake, our front office would be looking to rescue them from AAA too.
