NEW YORK — The New York Yankees are promoting infielder George Lombard Jr. to their major league roster. Lombard is the top prospect in the Yankees' system and ranks 20th overall among MLB prospects. The move signals a shift in the club's infield.

The call-up directly impacts the team's shortstop situation. Anthony Volpe is being demoted as part of the roster adjustment, ending the timeshare at shortstop that previously involved Volpe and José Caballero.

Lombard is expected to take over as primary shortstop. The Yankees have viewed his defensive capabilities as big-league ready. He also logged 11 starts at third base this season, adding versatility.

The promotion follows a strong offensive stretch. Lombard was sidelined for nearly a month in mid-June with a sprained left-hand fingers injury. Since returning, he has batted.377 with a 1.081 OPS across 65 plate appearances in 14 games.

The timing is deliberate. The Yankees want to give Lombard time to acclimate to major league competition before the stretch run and potential postseason. He has typically needed an adjustment period offensively when advancing to new minor league levels.

The move comes after general manager Brian Cashman pursued a shortstop before the trade deadline. Cashman said Monday he could not reach a deal for an external option. The organization now turns to its top internal talent to fill the need.

The Yankees had an open 40-man roster spot available. The team is set to select Lombard's contract, allowing his immediate addition without a corresponding transaction.

They failed to land a shortstop at the deadline, but they have a top-20 MLB prospect ready to step in with a hot bat and no questions about his glove. Giving Lombard this acclimation window is a smart play before the calendar gets unforgiving. Lombard is the Yankees' long-term answer at shortstop, and his arrival definitively ends the platoon setup.
