The New York Yankees have called up their top prospect, George Lombard Jr., to the major league roster. The move, announced Monday night, aims to bolster the team's shortstop position heading into the final stretch of the regular season.

Lombard, 21, was the Yankees' first-round draft pick out of high school three years ago. His promotion comes after a strong performance at Triple-A, where he recently returned from a month-long absence due to sprained fingers on his left hand. Manager Aaron Boone recently praised Lombard's development, noting his progress and talent.

"I think he’s had an outstanding year," Boone said recently. "I think he’s gotten better. I think he continues to show a ton of progress. We love the kid and the makeup. It’s been fun to see him – any of your minor league players or prospects, you want to see them develop and get better. In George’s case, obviously a high-profile one, that’s continued to happen. It’s a testament to his work ethic and his talent."
