Assuming he isn’t traded, of course… LaRoche’s breakthrough year came just as pretty much everyone was giving up on him. He looked just awful through April of last year, reaching his low point on May Day with a .195/.295/.442 line. Two weeks later he was at .221/.328/.451 when he lollygagged on his way to first base on a routine grounder, allowing Nick Johnson to beat him to the bag, sparking a Natspos rally that turned a close game to a blowout.

At about that time, LaRoche apparently started taking his ADD medication again. He also was shifted from fifth in the order to seventh (on May 9). He’d been hitting for power all year but was doing essentially nothing else, and at the end of a pretty decent May he was still mired at .239/.335/.497. On June 16th, Brian Jordan played his last game (ever, I devoutly hope) at first base for the Braves. LaRoche finally got to play every day, if only by default. At the end of June he was hitting .242/.323/.483. At the end of July, it was .268/.336/.533, LaRoche hitting .341/.372/.671 for the month. And in August, LaRoche was even better, .375/.464/.775.

Can he continue? I am generally suspicious of any chemically-aided improvement, whatever the chemical’s status is. That being said, I don’t know that the medication had any effect, and it’s not unusual for a player of LaRoche’s type to bust out a couple of years into his career. Baseball Prospectus ranked Tino Martinez as a similar player to LaRoche going into 2006, and Martinez broke out at just about the same point in his career. Mo Vaughn, who ranks as LaRoche’s most-similar player through Age 26 by Sim Scores, broke out at 25, in the third year of his career, then surged again at 26.

LaRoche had a pretty poor defensive year. As I remarked in last season’s comment, probably his biggest strength as a defensive player is as a receiver of throws, and the change from Furcal (strong arm, but erratic) to Renteria (The Rangeless Wonder, but steady) robbed that of most of its value… 0-4 career as a basestealer, but had his second career triple last year. Another reason to not move LaRoche up in the order (in addition to the lefty-lefty thing) is that you’d have two really slow guys back-to-back, clogging up the basepaths. Not that being on the basepaths ever came up much with the guy between them.
