Howie Kendrick has been one of my favorite prospects for a couple of years now. And the best comparable offensive player i have come up with in the minor leagues is Lastings Milledge. Both players hit for a high average from the right side. Both players have good power and have average plate discipline. Both players have good speed.
Howie Kendrick was 22 years old last year. In the Cal League(a hitter's league)he hit .384/.421/.638 with 12 homers, 23 doubles, 6 triples, and he was 13 for 17 in stolen bases all in 63 games. He basically destroyed the league. Moved up to the Texas League(which I believe is more of a pitcher's league, but correct me if I'm wrong) he hit .342/.382/.579 with 7 home runs, 20 doubles, 2 triples, and was 12 for 16 in stolen bases all in 46 games. Not as good as his A ball numbers but damn good numbers nonetheless. I always knew he could he hit but he has greatly improved his baserunning. Kendrick's defense at second base has improved from bad to average, and he probably will never be more than an average second baseman. His minor league career line is .359/.403/.555 in four seasons.
Lastings Milledge was 20 years old last year. In St. Lucie, A ball, he hit .302/.385/.418 with 4 homers, 15 doubles, 0 triples, and was 18 for 31 in stolen bases all in 62 games. Moved up to AA Binghampton he actually hit better. In 48 games he hit .337/.392/.487 with 4 homers, 17 doubles, 0 triples, and was 11 for 16 in stolen bases. Defensively Milledge is a very good outfielder. He has good range and a strong arm. He is a natural centerfielder but will probably play left field if he stays with the Mets. His minor league career line is .313/.382/.485 in three seasons.
I think Kendrick and Milledge are similar type hitters. I know it's probably difficult to compare them since one is an outfielder and the other is a second baseman that is two years older. But I have to ask the question, who would you rather have?
