Determining which infielders will make the roster will be the first truly difficult decision Aaron Boone has to make as the manager of the New York Yankees. Those fighting for spots are not making it easier on him, either. Greg Bird is penciled in at first, while Didi Gregorius is cemented at shortstop. Second base and third base, meanwhile, are up for grabs. Seven guys capable of playing at least one of those positions are battling for the starting jobs and bench roles. With spring training a few games in, let’s check in on the competitors at second and third and see what cases are being made. Brandon Drury Acquired from the Diamondbacks at the start of camp, Drury is off to a strong (unofficial) start as a Yankee. He is 4-11 this spring with a home run, a double and a triple. He has made solid contact. With 31 homers in 289 career games, Drury — according to Yankee general manager Brian Cashman — has yet to reach his full potential. He spent the offseason revamping his swing, looking for more power. He won’t be arbitration-eligible until next year, so the hope is that the 25-year-old is here to stay. Capable of playing third, second, first and some outfield, Drury is preferred by Cashman as a third baseman. From the moment he arrived in Florida, Drury appeared to be the favorite to start at 3B, but… Miguel Andujar … Andujar is giving him a run for his money. Drury afforded the Yankees more time to develop Andujar, their No. 5 prospect, but the rookie is making a strong argument that no further growth is needed at the minor league level. Andujar, 23, has been hotter than the Tampa sun this spring, going 8-19 with four dingers, eight RBIs and 22 total bases. Already considered by many a major league-ready hitter entering camp, he is leaving little room for doubt. At this point, it would be hard for the Yankees to send Andujar back to Scranton at the start of the season, but they may want him to work on his glove before handing him the third-base job. Tyler Wade After struggling in a brief major league showing last season, Wade is having a terrific spring. With a stroke tweaked by Albert Pujols, the lefty swinger is 5-14 with a pair of RBIs and a stolen base. The sample size has been small, but it’s easy to see that Wade’s retooled stroke is better suited for contact than in 2017. Even if that had not been the case, the Yankees love Wade for his flexibility. A natural shortstop, he can play every position except first and catcher. Right now, he’s a safe bet to win the second base job for Opening Day.
