NEW YORK -- This time, Robinson Canó ran out a ground ball.But as he approached first, he slowed up. He grimaced as he stepped on the base, and moments later, he left the game with left quad tightness, according to the Mets.Adeiny Hechavarria replaced him at second base to begin to fourth inning.Cano received an MRI during the game and the Mets expect to have an update Thursday.Mickey Callaway has been asked about why he never benched Canó for not hustling. For the most part, the manager has defended Canó in what looked to be indefensible cases.Regardless of Canó’s lapses, the Mets need him. They lost Michael Conforto last week and Brandon Nimmo on Wednesday. Jeff McNeil is out of Wednesday’s lineup because of hamstring tightness.With a decimated outfield, the last thing New York needs is a thin infield. The Mets can’t afford another injury, especially to a veteran that is supposed to be a team leader.The Mets have been a circus lately. There has been speculation regarding Callaway’s job security. Their star, Yoenis Cespedes, suffered ankle fractures because of a “violent fall” at his ranch.In the next you-can’t-make-this-up moment, Canó injured himself while running out a ground ball days removed from being criticized for not doing so.
