Per Chavez's agent (via MLB Trade Rumors). The Rangers had reportedly harbored some interest in bringing Chavez back, but he'll instead join the growing army of ex-Rangers that's building under the instruction of Buck Showalter up in Baltimore.
Chavez was recalled from Triple-A Round Rock in May to replace a fallen Julio Borbon, and ultimately ended up keeping Borbon's spot even after he regained his health, as Chavez maintained an OPS north of 1.000 over his first 60 plate appearances, and was hitting (a heavily BA-driven) .347/.376/.551 as late as July 19th.
The problem, though, was what happened to his performance beyond mid-late July or so ... here are his monthly performance splits:
May: 41 PA, .351/.400/.595, 176 wRC+, 0.6 fWAR
June: 50 PA, .283/.327/.435, 104 wRC+, 0.3 fWAR
July: 73 PA, .309/.324/.426, 91 wRC+, 0.4 fWAR
August: 62 PA, .281/.295/.368, 72 wRC+, 0.2 fWAR
September: 48 PA, .292/.292/.354, 68 wRC+, 0.1 fWAR
The numbers are indicative of a player who was relatively useful over the course of his first couple of months, and ... not so much beyond that point. Ultimately, though, the Rangers paid very little for some decent fill-in production in center field, and while there were a few downsides in that (such as, say, the Rangers still not figuring out exactly what they had on their hands in Borbon, as he was optioned to Round Rock once his alloted rehab time was up so that Chavez remain in Texas, and then proceeded to get hurt shortly thereafter), the Chavez/Rangers marriage ended up working out just about as well as anyone reasonably could have expected it to work out.
