By The Numbers: What the Acquisition of Alex Gonzalez Means for Milwaukee from a Defensive Perspective

By Kevin Kimmes

The offseason acquisition of Alex Gonzalez to replace Yuniesky Betancourt at shortstop may not at first seem like a very exciting move on the part of Milwaukee. Gonzalez, who turns 35 this year, is heading into the twilight of his career leaving some to wonder why The Brewers have gone and acquired another shortstop with roughly the same offensive output as Betancourt, when the departure of Prince Fielder has left a void in the run production department.  While it is true that Gonzalez has seen a decline in his offensive numbers (.241/.270/.372/.642 in 2011), the move makes perfect sense from a defensive perspective.

Consider this: according to Baseball-Reference.com, last season Milwaukee shortstops accounted for a total of 23 errors, 2 higher than the league average of 21, and tied for 10th most in the league with Boston, Cincinnati, and Washington. Of these errors, 21 were committed by everyday shortstop Betancourt.

By comparison, the Atlanta Braves (the former home of Gonzalez) committed a total of 14 errors at the shortstop position, ending the season tied for 5th least with Arizona. Of these, 12 were committed by Gonzalez.

Additionally,  according to The Bill James Handbook 2012, over the past 3 seasons (2009-2011) Gonzalez’s defensive play has led to 26 less runs being created  as well as 30 more outs created on grounders and flyballs when compared to an average shortstop. During this same period Betancourt was responsible for the creation of 46 runs due to poor defensive play, partially due to the fact that his outs created on grounders and flyballs were 56 plays below average (the worst at the shortstop position). That’s a variance of 24 runs and roughly 29 outs per season between the two.

So, will the addition of Gonzalez’s glove to the Brewers infield mean lower run totals for the teams opponents this season? Only time will tell. But, based on what the statistics show us, I would say that it is pretty safe to believe that we will be in for much higher quality defensive play this season from the infield.
