NEW YORK — In a surprise move, the New York Yankees announced that struggling catcher Austin Wells has been dealing with cervical headaches and has been placed on the 10-day injured list.Wells was replaced on the roster by J.C. Escarra, who had been demoted to Triple-A Scranton/Wilkes-Barre just 20 hours earlier.The moves happened just before the Yankees were to face the Boston Red Sox at Yankee Stadium on Saturday night. The game’s first pitch was expected to be delayed due to incoming rain, the team said.Manager Aaron Boone didn’t mention Wells’ headache issues in his pregame news conference, noting that he expected to give the lefty-hitting Wells off days soon against left-handed pitchers, because he’s struggled against them so much this season.According to the Cleveland Clinic, cervical headaches “can radiate from an injury or condition that affects your cervical spine, like an injury, arthritis or a slipped disk.”Wells, 26, has had a brutal season at the plate and seen his duties as the Yankees’ everyday starting catcher slip. His 54 wRC+ is the worst on the Yankees by a wide margin among hitters with at least 100 plate appearances. Through 47 games, he’s hit .166 with a .278 on-base percentage, four home runs, seven RBIs and 45 strikeouts in 169 plate appearances.After Friday’s loss to the Red Sox, the Yankees demoted Escarra, replacing him with catcher Ali Sánchez early Saturday. Escarra, 31, hasn’t hit either, posting a 38 wRC+ in 68 plate appearances. He’s hit .177 with no home runs, seven RBIs and 15 strikeouts.Sánchez, 29, hasn’t played in the majors yet this season. He had a .702 OPS in 40 games at Triple A. Boone said the Yankees view Sánchez as a strong defender. The manager added that while the Yankees liked that Sánchez finally provides a righty bat at catcher, it wasn’t the biggest part of the decision to promote him.
