Brian McCann was welcomed to The Bronx Thursday and Jacoby Ellsbury is up next. The Yankees are engaged with Robinson Cano and Shin-Soo Choo. Yet, the elephant in the room — starting pitching — isn’t being ignored, because after CC Sabathia and Ivan Nova there are three rotation spots open. “We have a need for starting pitching, and I would love to maintain [Hiroki] Kuroda,’’ general manager Brian Cashman said Thursday. “We have had a healthy dialogue so far, and I believe he wants to come back. He wants to pitch, here or Japan or someplace else, but there is no guarantee.’’ Kuroda, 39 on Feb. 10, went 11-13 with a 3.31 ERA in 32 games this past season and faltered down the stretch in his second Yankees campaign. He rejected the Yankees’ $14.1 million qualifying offer after making $15 million in 2014. Speaking at Thursday’s press conference, owner Hal Steinbrenner admitted there are more holes to fill after adding McCann and Ellsbury. “We need more hitting and want to sign Kuroda and we aren’t done with pitching,’’ Steinbrenner said.
