I find Grossman really interesting. He was a competent outfielder with the Astros. What happened last year that led to a disastrous -19 DRS? Yes, Houston is a much smaller park but that can't be everything... In 1320 LF innings with Houston, Grossman posted a +3 DRS. His RF stats were more limited - 280 innings - but he posted a +6 DRS over there so LF wasn't an aberration. Of course, we're dealing with relatively small sample sizes here, as his LF time in Houston is just shy of 150 full games. Still, that's not a tiny sample size. That's a reasonable baseline from which to start. As for the left side of the infield, a -28 DRS is certainly possible but Sano has been acceptable out there, posting a -3 DRS in 450 innings. That's a small enough sample size to almost be discarded entirely but it gives hope he's not entirely hopeless at third. If Sano plays a full season at that clip, it's around a -9 DRS for a full season. Polanco is the real wildcard here, IMO. HIs -8 DRS at short last season was abysmal, getting there in just 405 innings. My thinking is that Polanco won't be allowed to reach a -20 or lower DRS (which is where that tracks over a full season) and will be replaced by Escobar if things go that far off the rails. Which brings up another question about the left side of the infield... Escobar. DRS has the guy all over the place. It'd be easy to ignore his 2016 due to injury and "general awfulness" but DRS hated him in 2014, too. But in 2015, DRS thought he was an okay player. All were in limited but not unreasonably small innings, between 500-800 per season. Lots of questions about the left side of the infield but -28 seems a bit high to me. I think the defensive terribleness probably caps out around -25 DRS, as Polanco won't hang around at short if he's that bad and even if Escobar fails, I suspect the Twins will go glove-first at short relatively quickly, which will counter some of the awful play that preceded the move. Of course, it's hard to get a read on Sano, which will cause a lot of fluctuation. Is he a -5 DRS guy or a -15 DRS guy? We can assume Polanco will struggle but I'm unsure how badly Sano will struggle. He has an outside chance of being competent out there, particularly after losing weight and getting back into a rhythm at third.
