What we knew first was nothing. What we knew next was that Zack Greinke was going from the Brewers to the Angels, and that Jean Segura and two pitchers were going from the Angels to the Brewers. Now we have all of the details. The Angels are up one ace, and the Brewers are up three pretty good prospects.
Before the year, Baseball America ranked Mike Trout the No. 1 prospect in the Angels' system, of course. They ranked Jean Segura No. 2, Johnny Hellweg No. 4, and Ariel Pena No. 9. Segura is a 22-year-old shortstop. Hellweg is a 23-year-old righty who stands 6-foot-9. Pena is a 23-year-old righty.
The word on Segura is that he has a super-quick bat and average range in the middle infield. Hellweg gets his fastball into the mid- and upper-90s, with developing secondary stuff, which shouldn't come as a surprise since he's a relatively recent converted reliever. Pena is a fastball/slider guy with a live arm.
In terms of numbers, Segura has posted an above-average OPS in his first exposure to double-A. Hellweg owns a 3.38 ERA over 21 starts, but his strikeouts are low and his wildness has been high. Pena owns a 2.99 ERA over 19 starts, with nearly a strikeout an inning. None of these prospects are sure-fire awesome, but this is a talented haul for the Brewers given that Greinke was all but gone in two months, and God help us if Hellweg ever figures out what to do with his dangerous pitches. The stuff is there and the control is not yet, if you consider stuff and control to be unrelated.
