Gonzalez is almost the same as Yuni at the plate last year. Neither guy walks. Both have okay power. Gonzalez strikes out twice as much as Yuni. Over the last three years Gonzalez ranks a bit better, but not by a lot. And at 35, he's going to crash and burn before Yuni, who will be 30 next year. Defensively, Gonzalez is ranked better, but 2011 wasn't all that stellar. His UZR ratings show him steadily dropping. You have to wonder if he's fading (I haven't really watched him play lately, so I can't give any clear report on him). He turns 35 in Feburary, so it's not out of the question that he's simply lost some of his defensive pizazz. Gonzalez has been more inconsistent. He did quite good in 2010 (23 HR), but terrible in 2009, and nothing great last year (just a 1.1 WAR). In the end, I'd take the risk on Gonzalez than Yuni. He offers some hope of good - even average - fielding. And maybe the new environment would get him exciting and result in a bit of a bounce back year. If you get a 1.5 WAR out of him, you're showing a big improvement over 2011. 2011 Yuni: .252 BA, .271 OBP, .381 SLG, .652 OPS Gonzalez: .241, 270, .371, .642 2009-2011 Yuni:.252, .277. 381, .658 Gonzalez: .244, .281, .397, .678 WAR comparison (from fangraphs): Yuni/Gonzalez: 2011: 0.5 / 1.1 2010: 0.9 / 3.4 2009: -2.1 / 0.6 Fielding: 2011 Yuni: Fielding %: 19 of 22 qualified players Range factor: 19 of 22 Zone rating: 19 of 22 Gozalez: Fielding %: 5th of 22 Range factor: 16 of 22 Zone rating: 17 of 22 UZR Ratings: Yuni / Gonzalez 2011: -6.9 / -0.3 2010: -9.2 / 5.1 2009: -19.7 / 7.7
