When the Los Angeles Angels traded away shortstop prospect Jean Segura to land Zack Greinke, Kaleb Cowart immediately became the best prospect in Los Angeles' system.
It comes as no surprise that Cowart is the most notable of the eight prospects the Angels are sending to the Arizona Fall League.
Cowart spent time in both the Midwest League and the Cal League in his age 20 season, and succeeded at both levels. Amazingly, Cowart had the same exact number of at bats at both levels (263). Cowart hit .293/.348/.479. with nine home runs and nine stolen bases in the MWL, and then went on and hit .259/.366/.426 with seven home runs in the California League.
While it's a bit surprising to see Cowart's power numbers dip as he went to the homer-happy A+ league, Cowart's eye improved dramatically. Cowart managed just 22 walks in the MWL, but drew 45 walks after his promotion to the California League.
Between the two levels, Cowart hit a combined 16 home runs, while hitting .276/.358/.452.
As a switch hitting third baseman, Cowart has quite a bit of value as a prospect, and he should only improve over the next few years. Though Segura was unquestionable the better prospect in July, I think there's little doubt that Cowart had the highest ceiling all along between the two.
Though he's least a year and a half away from making an impact in Los Angeles, Cowart could actually give the Angels a run producer at third base at some point in 2014, or more realistically, 2015.
