NEW YORK -- New York Yankees rookie shortstop George Lombard Jr. was lifted from the second game of Saturday's doubleheader against Boston because of right knee discomfort.
The Yankees said Lombard was undergoing imaging at nearby New York-Presbyterian hospital. The team did not announce results of the tests, and manager Aaron Boone said Lombard was day-to-day.
During his at-bat in the second inning, Lombard checked his swing on a 2-2 pitch from Boston's Brayan Bello. After the swing, he grimaced and held his right knee.
"He felt like it was bugging him a little bit more and just seeing him that at-bat and kind of get down the line wasn't great," Boone said after New York's 9-2 nightcap win. "So just felt like we needed to get him out there."
An athletic trainer and Boone checked on Lombard, who stayed in the game and singled. Lombard also took his at-bat in the third, flying out to left field after the Yankees took a 3-1 lead. He did not take the field in the fourth.
José Caballero moved from third base to shortstop, and Amed Rosario entered the game at third for New York.
Lombard joined the Yankees on Aug. 4 and became the first New York shortstop to homer in his big league debut. The 21-year-old is hitting .253 with two homers and six RBIs in 23 games since getting promoted from Triple-A Scranton/Wilkes-Barre after the Yankees used Caballero and Anthony Volpe at shortstop.
Lombard also has committed seven errors. He became the first Yankee player with errors in six straight games since Chick Fewster in 1921 when he misplayed a grounder by Yainer Diaz in the eighth inning of Thursday's 5-1 loss to Houston.
