The Yankees made a low-risk, high-reward signing in Tulowitzki, who was released by the Blue Jays in December. The Blue Jays are paying the last year of his five-year, $100 million contract. If the veteran is able to return to the level of a serviceable major league shortstop, the Yankees won’t have to move Gleyber Torres off second base to fill in for the first half of the season. If Tulowitzki doesn’t work out, the Yankees are on the hook for only a minimal salary.
