Twins Video
And there was good reason for it. In 2015, between Chattanooga and Rochester, he had 28 errors in 102 games at shortstop. In AAA, he had a .908 fielding percentage at shortstop in just 19 games. In 83 games in AA, his fielding percentage at shortstop was just .942.
As noteworthy, I had people who watched him frequently last year wonder whether he could play any defensive position adequately. His arm was questioned at shortstop, but many saw that he struggled mightily just fielding the ball at times. His spring training performance this year was more than enough to understand why he was moving to second base.
Since that article was written, here is the breakdown of games and innings played by Polanco:
- 2B - 1 game, 9 innings
- 3B - 8 games, 70 innings
- SS - 34 games, 310 innings
In the first weeks or two following the Nunez trade, Polanco pretty much split time between third base and shortstop. However, with his start at shortstop on Sunday, his last 29 games have been played at shortstop.
What does our readership think of the Polanco defense at shortstop?
Here’s a look at some numbers:
- In 148 chances, Polanco has just six errors. That is a .959 fielding percentage.
- If you’re a fan of UZR (Ultimate Zone Rating), Polanco has been a -2.4. That equates to a UZR/150 of -11.3.
Both of those bullet points certainly indicate - in a small sample - that Polanco is clearly a below average defensive shortstop. Again, no surprise.
But can Polanco be a regular shortstop if this is the question: Can he make the routine play? For many, if you don’t have a shortstop with huge range, the key is for that player to make the routine plays.
In watching, the eye test tells me that he’s been solid. He’s made most of the plays. He’s had a half-dozen errors, but not many have been of the really bad category. My eyes tell me that he has been fine. Certainly not great. Maybe not even all that good, but certainly well within the realm of adequate.
Well, Inside Edge provides some numbers to FanGraphs to help quantify that. They break each ground ball into six categories: 1.) Routine, 2.) Likely, 3.) Even, 4.) Unlikely, 5.) Remote, 6.) Impossible. Here is how Polanco has fared in each of those categories:
Of course, for each of these categories, the sample size is far too small to make any grandiose statements. For the routine, 96.9% is low end of where you would want to be. However, that is 95 out of 98 which isn’t too bad at all. For the most part, Polanco has made the routine play. Of the likely category, four out of five isn’t too bad. Very small sample. Over time, you would certainly want this number to come up a little bit. “Even” would, in my mind, be a 50/50 proposition. Polanco is at 42.9%, but if he had made one more of those, he’d be at 57.1%, which could be good.
Unlikely,remote and impossible are all “bonus” categories, in my mind. Remote would be the great diving plays where not only you make the grab but are able to throw the runner out too. It appears that Polanco has been successful in one out of just four opportunities. I’m not even worried about the 15 that showed up in the remote or impossible categories.
A week or so ago, Nick wrote an article in which he discussed the scary idea of Polanco and Sano manning the left side of the Twins infield. It is difficult to envision. It certainly would not provide a lot of range. There would certainly be some limitations.
However, after reading Tom’s article on the Recent Success of 100 Loss teams, I am OK should the Twins and their new front office decide they would like to see that alignment on the left side of the infield.
Of course, should the Twins decide to trade Brian Dozier, Polanco could make the move to second base and they could go get a new shortstop.
At least in my mind, and eyes, and my review of the defensive stats (admittedly small sample), Polanco has expectedly been a little bit below average. However, I believe he has done enough to keep the experiment going, even beyond the 12 games remaining in this season.
