By the stats, he has been worse defensively than Nick Green this year, A-Gon has a higher fielding % but thats a weak stat, Nick Green's UZR/150 rating is 8, compared to 4 for A-Gon. But Green has gotten worse and worse as the year has gone on and Gonzalez is smart, unlike Green who thinks he can throw everyone out and usually throws it away. If Gonzalez can make the simple play then he is an upgrade.
But just so fans know, he is WORSE offensively than he was when he was here and isnt nearly the defensive player he was. Even though he is only a marginal upgrade, i love the move just because i want cannot stand watching Nick Green flail at pitches in the dirt and throw balls into the stands anymore. A-Gon is capable of getting on a hot streak with some power for a stretch, maybe we get lucky and it comes now.
