Brian Cashman isn’t messing around. The Yankees general manager pulled off another big move Tuesday, sending veteran third baseman Chase Headley and reliever Bryan Mitchell to the San Diego Padres for outfielder Jabari Blash, Joel Sherman of the New York Post first reported. The most impressive part of the deal isn’t Blash’s 6-foot-5, 235-pound frame. It’s the fact that Cashman got the Padres to take all of Headley’s $13 million salary in 2018. The move will push the Yankees even further below the $197 million luxury tax threshold next season, thus freeing them up to pursue high-end starting pitching this offseason or perhaps set them up to make gigantic splashes next offseason when such stars as Bryce Harper and Manny Machado are expected to be free agents. The trade also allows the Yankees to bring more of their highly touted prospects up from the minors. Gleyber Torres, who is currently working his way back from Tommy John surgery on his left elbow, could find himself starting at third base next season.
