NEW YORK (AP) Yankees star shortstop Didi Gregorius needs Tommy John surgery on his right elbow after injuring himself making a throw in Boston during the AL Division Series, and there's no telling exactly when he'll be able to play again.

General manager Brian Cashman said Friday that Gregorius will be out "until sometime next summer." Cashman said the team will have a better idea about his return after surgery, which hasn't yet been scheduled.

The surprise announcement at Yankee Stadium led to immediate speculation the team might eventually make a big move to fill the void - pursuit of All-Star infielder and free agent-to-be Manny Machado, now in the NL playoffs with the Los Angeles Dodgers.
