New York Yankees slugger Giancarlo Stanton is uncertain for opening day because of chronic tendinitis in both elbows.

A five-time All-Star, the 35-year-old dealt with the issue last season and through the postseason, when he hit seven home runs as the Yankees reached the World Series for the first time since 2009.

Asked whether the issue could impact Stanton’s availability for the March 27 opener against Milwaukee, manager Aaron Boone responded: “Tough to say.”

“I’m not going to put any timeline on it. We’re just going to be smart with it and kind of listen to it a little bit,” he said Sunday. “I’m expecting him to be OK. It’s just a matter of when we’re going to start really rolling it out to feel like — give us the best chance to get as much of him as we can.”

In addition, outfielder Trent Grisham pulled his left hamstring a few weeks ago in training but is running at close to full speed.

“He shouldn’t be too far behind,” Boone said.

Boone made the announcements as position players reported ahead of Monday’s first full-squad workout.

“Giancarlo’s a little behind just dealing with some elbow stuff that he dealt with last year, actually both elbows kind of really akin to tennis elbow,” Boone said. “This is something that if we’re full bore in we’d be grinding away probably, but just want to make sure we give it the proper time and just give ourselves to be the best position throughout the year.”

Stanton batted .273 with 16 RBIs in the postseason. He was exclusively a hitter last season and has not played the field since Sept. 9, 2023.

“He’s huge for us, ”Boone said. “You take a big right-handed bat out there, you’re a little unbalanced there.”

Arenado reports to Cardinals camp >> St. Louis Cardinals third baseman Nolan Arenado reported to spring training, showing up to play for a team that spent much of the offseason trying to trade him.

The eight-time All-Star and 10-time Gold Glove winner is owed $74 million for the next three seasons.

Colorado will pay St. Louis $5 million this year, the final installment of the $51 million the Rockies agreed to pay to offset the $199 million remaining in a nine-year contract worth $275 million to finalize a trade four years ago.

The Cardinals could not move him and his contract, which gives Arenado a full no-trade provision.

“I’m not going to talk about who the teams were because it doesn’t really matter anymore, but so, yeah, there was about five teams, five or so,” Arenado said. “I got a family now and to be willing to pick up my family and move them, it has to be something that is worth it.”
