NEW YORK -- Yankees slugger Aaron Judge was held out of action for a second straight day Sunday due to a stiff neck.

The 2017 AL Rookie of the Year was scratched from a simulated game Saturday after waking up with a sore neck, and the right fielder was not included in either lineup for an intrasquad scrimmage Sunday.

New York manager Aaron Boone said Judge got treatment at Yankee Stadium on Sunday and was improving.

"Just thought it was better not to push through it today," Boone said.

The Yankees are set to open a pandemic-shortened season July 23 at Washington.

Judge was diagnosed with a broken rib in March and used the coronavirus hiatus to recover. He had been swinging at full strength for at least a couple of weeks before camp opened and had been a full-go in intrasquad action over the past week.

The 6-foot-7 star has missed time each of the past two seasons. He broke his right wrist from being hit by a pitch in 2018 and went on the injured list for two months last year with a left oblique strain.

Right-hander Masahiro Tanaka played catch Sunday to 100 feet and is ramping up his cardio but remains in the concussion protocol. The Japanese starter was hit in the head by Giancarlo Stanton's 112 mph line drive eight days ago. Boone is still uncertain when Tanaka will return to the mound.

Boone said Clint Frazier is expected to resume playing the outfield this week after being limited to designated hitter so far due to plantar fasciitis in his right foot.
