Polanco, Shortstops, and Stability

Over the past 13 seasons, dating back to 2005, the Minnesota Twins have started 11 different players at shortstop on Opening Day. Through those years, only Pedro Florimon has been given the nod in back-to-back seasons (13-14), and Jason Bartlett is the only other player to appear twice (05 & 07). To put it simply, consistency at the shortstop position isn't something that the Minnesota Twins have had in over a decade. With Jorge Polanco settling in to change that notion, it might be time to give it some real thought.

To know where the Twins may be going, we'll first take a look at where they've been. Before the revolving door got started in 2004, the last point of stability was none other than Cristian Guzman. From 1999 through 2004, the Dominican native started every Opening Day for Minnesota, and racked up 841 games played. A fixture in the Minnesota lineup, Guzman was a serviceable option that allowed speed to carry his game.

At the dish, you could argue that Guzman was a relatively replaceable asset. Owning just a .685 OPS with Minnesota, and averaging just a .303 OBP over his six-year tenure, there was nothing that jumped off the stat page. Leading the league in triples three times, and stealing double-digit bases in five straight years, quickness was highly valued at a time in the game where advanced analytics had yet to break in.

In the field, Guzman was as acceptable as it gets. Defensive data at Fangraphs only goes back to 2002, but over the three seasons accounted for, Guzman provided two at a net zero outcome. Both in 2002 and 2004, a total of 0 DRS was the result in over 1,200 innings. He displayed solid zone ratings, and above average range at the most demanding position in the infield however. In short, Guzman was the option for Minnesota because he did just enough to warrant the job, but also never really pushed the needle.

As the game has evolved, shortstops are among the most premier players on the diamond. To have a guy with an OPS south of .700 and be worth nothing more than league average defensively, you'd be hard-pressed not to insert the Pedro Florimon's of the world as a replacement. Fortunately for Minnesota, looking at stability this time around provides something of a significant advancement in the form of Jorge Polanco.

The former top-100 prospect will be entering his second full season as the Twins everyday shortstop. He's coming off a .723 OPS and a -1 DRS across 1,119 innings played. The sample size compiled thus far is incredibly small, but given a brief taste in 2016, we can quantify improvement. In the field across 69 games in 2016, Polanco owned a -8 DRS across 406 innings. With questions regarding his arm at short, the initial showing did nothing to dispel the notion that he wasn't fit to play anything but second base at the highest level. Displaying substantial improvements across the board, and a positive RngR factor last year though, Polanco put forth an effort reflective of lots of extra offseason work.

Regarding Polanco, it's always been the bat that was expected to carry him. After bottoming out at a .572 OPS on August 4th last season, a corner was turned. Over his final 53 games, Polanco posted a .942 OPS that saw him launch 10 homers and pick up another 14 doubles. Everything from launch angle to pitch recognition was maximized, and the turnaround was more reflective of the player Minnesota expected to have coming out of their minor league system.

Knowing baseball is a mental game, the loss of Polanco's grandfather likely weighed on him at points of the season. Widely reported as a father figure to the 24 year old, it's hardly unfathomable that performance would dip as his mind struggled to stay engaged. On the field, locking back in to a disciplined approach that produced career bests in SwStr% and chase rate no doubt aided the turnaround.

Looking ahead, Polanco should be in a position where he can secure the shortstop role to the point that a challenger needs to wrangle it away from him. The revolving door has stopped spinning at this moment, and by the time Royce Lewis or Wander Javier are ready for the next step, Polanco should allow Minnesota an opportunity to make them earn it. It's not far off that an up-the-middle tandem of Polanco and Nick Gordon can be seen as reality, but there should be little question in regards to who's best suited at short among that duo.

For any number of organizations across the big leagues, having answers on the mound, at short, and in center remain of the utmost importance. More often than not, the Twins have done well in center, and they've begun to right the ship on the mound. Polanco taking steps forward to own shortstop is a much-needed revelation, and it's one that he's only begun to own into. Obviously the sustainability of a .900+ OPS isn't great, but a full season of Polanco contributing with both the bat and the glove seems to be more expectation than hope at this point.
