Jorge Polanco picks up some fielding tricks from Twins teammate Andrelton Simmons

CHICAGO — Jorge Polanco ranged to his right in the first inning Tuesday night, got his glove on Tim Anderson's grounder up the middle, and snapped a throw to first base before he even got another foot on the ground — a noticeably faster motion than he once used.

It was akin to the technique of another middle infielder standing about 40 feet away.

"If you pay attention to him, you know Andrelton [Simmons] is one of the best shortstops. I've done a lot of things with him that have helped me," Polanco said. "I'm not trying to be like him. I just copy some ways that help me, and make it look easy like he does."

The ease with which Simmons throws is particularly noteworthy; he sometimes even fires a ball across the diamond flat-footed, in order to save time. One good example: A double play against the Tigers in Target Field earlier this month, in which Polanco dove for a ground ball in front of second base, flipped the ball out of his glove to Simmons, who was standing on the base and fired a relay without moving his legs.

"It just happened, all reaction. I just dove and flipped it from the ground," Polanco said. "I didn't think about it, and he made that throw."

Advanced defensive statistics rate Polanco about an average second baseman, better than he rated at shortstop. Twins manager Rocco Baldelli said he's noticed Polanco's defense getting stronger, perhaps from Simmons' influence, and perhaps more because of his rising comfort level as his new position.

"It's related directly to his confidence. He's making certain plays, going in certain directions much more smoothly, quickly and more confidently," Baldelli said. "When I first showed up here, I didn't think he got rid of the ball that quickly. He and [third base coach] Tony Diaz spent a lot of time working on throwing from different angles, throwing on the run. He's significantly more comfortable doing all of these things."

Now that Mitch Garver is back, Baldelli must determine how to split the catching duties. He intended it to be close to 50-50 with Garver and Ryan Jeffers when the season began, but that changed when Jeffers was sent to Class AAA on April 29. He was recalled June 2, after Garver suffered a severe groin injury.

"Are we going to put a number on exactly how many games each guy is going to catch every week? I would say no. I'd say it's going to be a rough split," Baldelli said. "Over time, if there is a guy that's playing especially well, someone may be catching four games a week, someone may be catching three games a week. Both are going to play, though."

Speaking of catchers, every manager fears running out of players who can play the position. The Twins might be more at risk than normal, with only two experienced catchers on the roster, one of whom is returning from a serious injury.

So who is the emergency catcher?

Josh Donaldson, a catcher in the minor leagues, volunteered for the job, Baldelli said, but he's leery of risking the third baseman's health.

That was news to Jeffers. "I'm surprised it isn't [Miguel] Sano, actually," he said. "You know, just get the biggest target, someone who can get a glove on the baseball."
