Remember that this list is based entirely on statistical performance in 2010, and is not a traditional "best prospects" ranking.
30) Clayton Fuller, 6/17/87 - CF, High A and AA
.238/.328/.378 with 10 HR and 17 SB. +2 bat, +5 glove, 1.86 WAR.
It was a bizarre season for Fuller: the twenty-three year old was severely overmatched in AA, managing just .168/.241/.240 in 237 PA's through the first half. He then responded to a June demotion by exploding in the Cal League (like I thought he would in '09), raking to the tune of .331/.432/.565 with 6 HR's and 12 SB's in 183 PA's before getting hurt in August. Note that while his bat was worth +17 runs in Rancho Cucamonga, he cost the Arkansas Travs something like -15 runs in the spring. He has one more year to prove himself in AA before the Halos either add him to the 40 man roster or risk losing him.
29) Rich Thompson, 7/1/84 - RHRP, AAA and Majors
1 Win, 1 Loss, 2 saves. 29.2 IP, 17 hits, 0.61 ERA, 30 K/10 BB. +15 runs saved, 1.92 WAR
I'm glad Thompson finally stuck in the majors, because I've been rooting for him for years. Apparently his cutter is getting much of the credit, but his mid 90's fastball and hard-diving curveball have both been very good for some time. In fact, his curve had the highest whiff rate of any of his pitches (a well-above average 15.4%). I think he continues to stick in 2011.
28) Suammy Baez, 9/28/88 - RHSP, Single A, Arizona Rookie League
4 wins, 4 losses . 83.2 IP, 86 hits, 2.69 ERA, 81 K/25 BB. +10 runs saved, 2.02 WAR
He turned twenty-two and gave up over a hit an inning in rookie ball. He'll likely be a usable organizational guy, which is good news for the Halos since they are entering 2011 short on pitching depth in the lower minors.
27) Casey Haerther, 10/5/87 - 1B, Single A
.307/.352/.432 with 8 HR. +6 bat, +8 glove, 2.07 WAR
After playing third base with the Pioneers in his pro debut, Haerther shifted to first base with the Kernels, the position he played back in the day with UCLA. TotalZone has him playing excellent defense in addition to hitting for good average. On the other hand, his power stroke never really showed up, disappointing for a college first baseman selected in the fifth round. He's going to have to have to explode in the Cal League in order to hop Gabe Jacobo on the depth chart.
26) Chris Scholl, 10/27/87 - RHRP, High A
2 wins, 1 loss. 68.2 IP, 64 hits, 3.41 ERA, 82 K/20 BB. +12 runs saved, 2.13 WAR
For the second straight year, Scholl had an outstanding second half. The Halos haven't been aggressive promoting him, allowing him instead to spend a full season at each level, and so far he's rewarding their patience with a steadily increasing K-rate (up to 10.7 per nine in 2010). I liked his stuff better than Eddie McKiernan's when I saw them pitch last April, but the Halos must have their reasons for not pushing Scholl into a higher profile role.
