YES Network’s Jack Curry reports the Yankees are calling up top prospect George Lombard Jr. from Triple-A Scranton/Wilkes-Barre.

Lombard will make his major-league debut against the Cardinals on Tuesday at Yankee Stadium. The 21-year-old remains a work in progress from an offensive standpoint at this stage of his development, but he’s shown some real over-the-fence pop at the Triple-A level this season. He’s a phenomenal defender and projects as New York’s long-term answer at shortstop, which means they can finally end the bizarre José Caballero and Anthony Volpe timeshare once and for all. He may not provide an instant fantasy impact outside of deeper leagues, but Lombard in a prospect worth monitoring closely, even in shallow mixers.
