Let's not get carried away here, people. Wright is going to be big in the future, but Eric Chavez is entering his prime. He had his best season last year and that was partially interrupted by an injury after he got hit by a Marte pitch on the hand or wrist. His OBP rose 47 points last season, he hit 29 homers in under 130 games. Chavez is only 27, so it can be expected that this improvement was for real. Most of the improvement was due to gains vs. left-handed pitching, which makes sense, because the only way for you to improve in that department is to get more ABs vs. them. Chavez has.
I'd keep Chavez.
