There was clearly something different about Polanco's approach. In April and May he struck out about once every 8 at bats. That's a bit better than his career rate of once every 6 at bats. That's the kind of progression one would expect as a player gets more experience. But in June and July, he struck out out once every 4.6 at bats. That's Sano range, actually, it's still better than Sano. But Polanco doesn't have Sano power. So far in August, 1 K in 17 at bats. So, the long and the short of it is that Polanco appears to be back in his game. His game is contact with occasional gap power. He doesn't walk much, but he also usually doesn't strike out much. His ceiling is probably an OPS in the low .700 range if he develops a little more power. More likely .680 to .700. That's just who he is. Is he a replacement level player? Yep. But that's the reality of mid market teams. The Twins are never going to field a roster full of All Stars. Sometimes, someone who is "good enough" will have to be good enough until the organization develops a better, cheaper, option. Right now, Polanco is cheap. And if he posts an OPS+ in the upper 90s to low 100s, that will probably keep him in the lineup if he plays good enough defense. Right now the jury is still out in that regard. As with his hitting, he seemed fine in April and May and really stunk it up in June and July. The "eye" test tells me that early his issues were throwing. In June and July, he had problems getting the glove on the ball. That's a concentration issue. Take note of what his numbers are now and see if they improve by the end of the year. Right now, he has a UZR/150 of -1.2. That's not good, but it is substantially better than the -32.3 he posted last year. For the most part, based on "inside edge" fielding stats, he's making most of the plays he should be. His biggest area for improvement is in the "Likely (60-90%)" area. He's making 67% of those plays. Like to see that at about 80% or better IMO. FWIW, Escobar is a -.2 UZR/150 at SS in 2017 (SSS of course), after posting a -11.8 last year. IMO, Escobar would be a better fit in the NL, where the bench is a little longer. He's good enough to start semi-regularly, but will be exposed if he were to play 140 games a year. And of course, he would be a good bat off the bench and a good guy to use for a double switch. In the AL where the norm is 3-4 man bench, the opportunities to pinch hit or platoon just aren't there like they were 20 years ago. Again SSS, Adrianza has a 3.5 UZR/150 at SS in 2017. Adrianza kinda strikes me as an older, albeit less experienced version of Polanco. Substantially better defensively though. My gut tells me he isn't cut out to start 130, 140 games a year. Ideally suited to be a more "traditional" reserve though.
