“Usually these things pop up every now and then — it’s usually a dive or slide where you just kind of jam your shoulder or jam your neck a little bit,” Teixeira said. “Then you start getting some spasms.”

Teixeira underwent treatment all day on his neck. He doesn’t want to use the injury as an excuse for his poor numbers — he’s hitting just .202 with three homers and 11 RBI — but he felt as though he was altering his swing because of the discomfort. Joe Girardi concurred.

“Your neck is fairly important in a swing because you have to be able to turn your head and sometimes players can’t work the way they want to work because they’re dealing with some stuff,” Girardi said.

“I think he’s been patient. I don’t think he’s gotten fully on track this year, but I think he will.”

CAN ELLS AVOID DL?

Centerfielder Jacoby Ellsbury hasn’t played since Friday because of a hip he tweaked against the Red Sox. For now, the Yankees want to avoid placing Ellsbury on the DL, but Girardi said if Ellsbury hasn’t played in a week, the team “might as well” make the move and backdate the stint to May 6, when Ellsbury initially suffered the injury.

Ellsbury was slated to take swings and do some light running outside on Tuesday.

“The hurdle that he really has to clear is sprinting,” Girardi said of Ellsbury.

A-ROD PROGRESSING

Alex Rodriguez, who is on the 15-day disabled list because of a strained right hamstring, has run on the Alter-G treadmill and “feels a lot better,” according to Girardi.

The Yankees are hoping the right-handed slugger will be available at the end of 15 days, which would mean a May 19 return at the earliest. But the team won’t know for sure until Rodriguez is able to run on the field and test out his leg.

“The Walking Wounded all seem to be doing better,” Girardi said jokingly, referring to his growing horde of injured players. “But it’s baseball season, you’re in the midst of it now.” RAUL Mondesi Jr., the son of former Yankees outfielder Raul Mondesi, received a 50-game suspension without pay after testing positive for Clenbuterol, Major League Baseball announced Tuesday.

Mondesi Jr., a 20-year-old infielder who is on the Royals’ 40-man roster with Northwest Arkansas of the Texas League (Double-A), tested positive during spring training after using a cough syrup that is manufactured in the Dominican Republic, sources told the Daily News.

The medication, labeled Subrox-C, is an over-the-counter product sold in the Dominican, and sources say it is the same medicine former reliever Guillermo Mota used when he tested positive for Clenbuterol, a stimulant, in 2012. Mota was suspended 100 games that year. Mondesi Jr. was born in Los Angeles while Mondesi Sr. was born in the Dominican.
