Gregorius got off a to a shaky start in 2015, hitting just .206 in April while committing numerous fielding, baserunning and mental errors, but he was able to turn things around as the season progressed. The shortstop finished the year hitting a respectable .265, providing plus defense and becoming one of the team's more reliable hitters amid a roster full of late-season slumps and injuries. The lefty also showed improvement against southpaws, slashing .247/.311/.315 after being a liability against lefties in his first two seasons, and he sports a .626 OPS compared to just a .554 mark in his career versus southpaws. He'll turn 26 in February, so there's still plenty of room for his game to continue developing, and the Yankees will gladly take his solid offensive production (for a shortstop) and the defense that he displayed for most of the season.

The Diamondbacks chose Chris Owings over Gregorius as the team's primary shortstop to begin the 2014 season, but Gregorius entered the mix in June after hitting .310/.389/.447 at Triple-A Reno. Defense is still Gregorius' calling card, but his room for growth as a hitter remains debatable. With a 6-foot-2, 205-pound frame, the left-handed hitting Gregorius doesn't fit the physical mold of a light-hitting shortstop, but his production fell across the board last season. For his career, Gregorius has a .243/.313/.366 line, 13 home runs, 57 RBI and 83 runs scored over 724 plate appearances, but he's maintained an acceptable level of plate discipline (17.4% K%, 7.4% BB%). Thus far, he's shown no ability to handle left-handed pitching at the big league level, striking out in 25 percent of his plate appearances and carrying a .184/.257/.233 line against southpaws. Acquired by the Yankees via trade in December, Gregorius will replace Derek Jeter at shortstop in the Bronx in 2015.

Many scouts said Gregorius was a weak bat, and early on, that didn't appear to be the case (he went deep in his first at-bat as a Diamondback against the Yankees). His hot April and May eventually cooled and he became the hitter most expected, finishing the season with a .252 average and .332 OBP. While he is a potential trade candidate given the D-Backs' organizational depth in the middle infield, his glove will assure him playing time regardless of where he's playing in 2014. Unfortunately for fantasy owners, it's difficult to project an overwhelming improvement from his 2013 numbers at the plate.

The line on Gregorius remains the same - he has a fantastic glove that the scouts love, but it's up for debate whether his bat will be good enough to carry in a major league starting lineup. The game has evolved to emphasize defense more, so there's a chance yet that Gregorius could make it, but many were surprised when the D-Backs were willing to deal Trevor Bauer away in December to acquire him. It's believed that he will get more time at Triple-A to continue the development of his bat, but the trade should significantly accelerate his timetable to the big leagues. Despite his range in the field, Gregorius is not proficient on the basepaths, having stolen just three bases against nine attempts in the minors last year.

Gregorius hasn't done a whole lot at the plate in his professional career. His .790 OPS at High-A last year was at an extreme offensive environment in Bakersfield. Otherwise, his career OPS has hovered around .700. He just turned 22 in February, so there's time for his bat to catch up to his glove, which is superb. He's about a year-and-a-half away from getting tested at the major league level. He's there as glove-first insurance in case Zack Cozart can't cut it at the position.
