Polanco was impressive at the plate last season when given a trial as the team's everyday shortstop as he hit .288 with a .751 OPS over his last 56 games. However, there were questions about his defense which could ultimately move him to second base. Still, this shows Polanco is ahead of Eduardo Escobar at shortstop, although the Twins could still shake up their roster this winter.
Travis Shaw headlined the return for the Brewers, but Dubon was the second most noteworthy piece. While he would have only profiled as a utility player in Boston, there is a chance he could earn more playing time when he reaches the big leagues on the rebuilding Brewers. After performing as a slightly above average hitter in the lower levels of the minors, Dubon exploded after a promotion to Double-A last year, slashing .339/.371/.538 with six home runs and six steals in 269 plate appearances. His slight 6-foot, 160-pound frame won't lend itself to power in the majors, but he has the contact skills to hit for a solid average while stealing double-digit bases over a full season. The 22-year-old shortstop played some outfield in the Arizona Fall League, but will likely return to the middle infield with an assignment to Triple-A Colorado Springs. The most likely outcome is that Dubon serves as a utility infielder for Milwaukee in 2018, but if a spot opens up at second base, he has the potential to be an average regular there.
He was believed to be a non-tender candidate, but ultimately Escobar and the Twins were able to land on a number that was suitable for both sides. Escobar hit just .236/.280/.338 in his age-27 season, but he was significantly better at the plate in 2015 and can play shortstop, second base and third.
The soon-to-be 32-year-old attended big-league camp with the A's last spring but opened the year at Double-A. Rodriguez eventually returned to the Triple-A level and posted a 24:25 BB:K with the top affiliate, and he also has a bit of power, but he will be a long shot to break camp with Oakland. He's bounced between with five different organizations in his 11 pro seasons and hasn't reached the majors since 2011.
The highly-acclaimed prospect, who was acquired from the Cubs in the Aroldis Chapman trade, began the transition to second base and slashed .254/.341/.386 in 138 plate appearances for High-A Tampa following last season's trade. Yankees general manager Brian Cashman said Torres will begin the season with Trenton and get introduced to cold weather for the first time, with his performance determining a potential promotion, despite being just 19 years old.
It was well known that the Mariners were looking for an upgrade at shortstop and they landed a significant one in Segura. He put together what was easily his best season in his age-26 campaign, batting .319/.368/.499 with 20 homers and 33 steals (43 attempts). While he now goes to a more pitcher-friendly home park and will play for a manager in Scott Servais who didn't run a whole lot this past season (24th in stolen base attempts), Segura's batted ball profile from 2016 and speed bode well for his chances of once again providing quality production atop the lineup.
This was a no-brainer for the Yankees as Mateo is a top prospect in the system and needed to be protected from the Rule 5 draft. He did endure some growing pains at High-A Tampa in 2016, but Mateo has elite speed and there's optimism about his hit tool developing in time. There's been talk about him potentially moving to center field long term.
Urena splitting time between High-A Dunedin and Double-A New Hampshire, combined to hit .295/.335/.434 with eight home runs and 59 RBI. He figures to stay with New Hampshire to begin 2017 since he only spent 30 games there, but he has progressed enough that protecting him from the Rule 5 draft became necessary.
His prospect stock has taken a hit in recent years, as he's totaled just five homers over the past two seasons, but Robertson continued to get on base at a good clip in 2016 thanks to an 11.4 percent walk rate. He saw more time at second base and third in 2016 with 20-plus appearances at each position.
Adames hit .274/.372/.430 with 11 homers and 13 steals in 132 games with Double-A Montgomery in 2016, solidifying his status as the top prospect in the organization. He will presumably advance to Triple-A early on in 2017 with a chance to break through to the majors before the end of the year.
