In parts of three seasons in AA (his age 23, 24 and 25 seasons), the 26-year old has hit .255/.357/.422. However, his numbers have declined every year from a 1.062 OPS in 18 games in 2010 to an .827 OPS in 2011 to a .691 OPS in 94 games in 2012 when he hit .215/.340/.351 and struck out 113 times in 94 games. He's also immobile these days. It's sad in a way how much injuries have changed his game, and what his body can do.
Like Havens, Holt's carrer had stalled at AA, where he has been working out of the bullpen for most of the last two years with modes success. In 2012, he put up a respectable 3.40 ERA in 47.2 innings with 42 strikeouts. However, he walked 13% of the batters he faced (28 of 212) and did so with an average ish fastball and a below average slider. Given a chance in AAA, he was bombed in six appearances: 5.1 IP, 11 H, 6 R, 6 ER, 4 BB, 3 K. Yikes. There were at least a few teams interested in Holt when the Mets left him unprotected in this past year's Rule 5 draft, so I expect he'll get picked up somewhere now that doing so is totally costless.
