NEW YORK — Yankees reliever Jake Cousins felt pectoral discomfort after throwing a pair of batting practice sessions, another setback in his bid to return to the mound for the first time since last fall.

Cousins won’t throw again for four or five days, manager Aaron Boone said Saturday.

Boone said ahead of spring training’s opening workout that Cousins had a strained right forearm and was uncertain for the March 27 opener.

A 30-year-old right-hander, Cousins threw batting practice to injured slugger Giancarlo Stanton on May 6. Boone said Cousins pitched an additional session before the pec issue caused a shutdown.

“We don’t think it’s anything serious, but enough to hold him back a few days,” Boone said.

Boone said Cousins had tests and that they didn’t show any shoulder issues.

Cousins had a 2.37 ERA in 37 relief appearances last year, striking out 53 and walking 20 in 38 innings.

Boone said a date has not been set for Stanton to start a minor league injury rehabilitation assignment. The five-time All-Star has been sidelined since spring training with pain in the tendons of both elbows.

The Minnesota Twins are on a roll. They extended their winning streak to 11 games Thursday with a 4-0 win over the Baltimore Orioles that completed a series sweep. Their confidence carried over to social media, too, as they trolled the Orioles.

Minnesota used a three-run third inning to propel itself to victory, with home runs from DaShawn Keirsey Jr. and Byron Buxton.

The Twins hold the longest win streak in MLB; its their their longest run of victories since winning 12 straight from April 22 to May 4 last season, according to ESPN Research. The franchise record is 15 set in 1991.

Minnesota poked fun at Baltimore’s namesake with a post after the game, referring to the Orioles also being known as the “O’s” — and swapping a zero in for the O.

The Twins have won each of their six matchups against the Orioles this season. All of them have come during Minnesota’s current win streak.

Minnesota (24-20) is fourth in the American League Central behind the Kansas City Royals, Cleveland Guardians and Detroit Tigers.

Star Boston Red Sox rookie Kristian Campbell has started working out at first base in the wake of Triston Casas‘ season-ending knee injury.

Campbell worked out at first before Friday night’s series opener against the Atlanta Braves at Fenway Park, and Red Sox manager Alex Cora addressed the situation when he spoke to reporters before the game.

“Looking for options,” Cora told reporters. “Obviously, we’re getting Romy [Gonzalez] probably at the end of the week, early next week, but just introduce him to first base and see how he looks. That’s where we’re at.”

Casas ruptured the tendon in his left knee while running to first base during a game against the Minnesota Twins earlier this month. His replacement at first, Gonzalez, was placed on the 10-day injured list because of a left quad contusion last week.

One potential replacement, star slugger Rafael Devers, said after Casas went down that he would not be open to moving to first after he went from third base to designated hitter during spring training to make room for Alex Bregman.

Campbell, one of baseball’s top prospects, broke camp with the big league team and has been its primary second baseman through the start of the season. He has also played in the outfield and at shortstop and third base in his career, but never first.

Asked what he would need to see for Campbell to be a realistic option at first for his team, Cora added: “The process started, right? It can take 10 days, 15 days, a month, two months. But we started the process and introduced him to first.”
