The Boston Red Sox still yet to finalize their contract with prized free agent J.D. Martinez.

Manager Alex Cora said after Boston’s Grapefruit League exhibition opener against Minnesota on Friday that he’s not bothered by the delay and is simply focused on preparing the players he already has in camp.

“We’re still working and getting ready, you know? That’s all we can do,” Cora said after the Red Sox beat the Twins 4-3 at JetBlue Park in in Fort Myers.

Martinez agreed to terms on Monday to a deal that’s as long as five years and worth as much as $110 million, according to a person familiar with the negotiations who spoke on condition of anonymity because the contract is subject to a successful physical exam and has not been announced by the club.

The Red Sox were more than eager to welcome an accomplished, potent bat like Martinez’s to the lineup after an offseason when the rival New York Yankees flexed their muscle by adding slugger Giancarlo Stanton.

“To be able to combat those moves with a guy like J.D., that was a good move,” Red Sox pitcher David Price said.

High school honored

Spring training got off to a solemn start as MLB teams wore hats to honor Marjory Stoneman Douglas High School in Parkland, Fla., where 17 people were fatally shot nine days ago.

Stoneman Douglas baseball coach Todd Fitz-Gerald and his two sons were guests of the Houston Astros for their spring opener against the Washington Nationals. Members of the school’s baseball and softball teams were guests of the Marlins and mingled on the field with players, coaches and CEO Derek Jeter.

Union refusal to sign

A proposal collapsed that would have put a runner on second base to start the 10th inning of spring training games, a person familiar with the negotiations said.

The players’ association refused to sign the spring-training deal Wednesday, the person added.

The person spoke on condition of anonymity because no statements were authorized.

Management thinks the union backed off because players were upset Commissioner Rob Manfred described pace-of-game rules that apply to the regular season as an agreement, the person said. The union makes the distinction it did not agree to the rules but instead will not challenge MLB’s decision to unilaterally impose them.

The rules include a general limit of six mound visits without a pitching change by managers, coaches and players.

Union head Tony Clark said in an email to the AP that “to suggest that this didn’t get done based on recent commentary alone is grossly misleading.”

Nice debut

Aaron Boone walked to home plate for his first game as a manager at any level and was greeted by Detroit’s Ron Gardenhire, a 60-year-old baseball lifer back in charge of a big league team for the first time in four years.

“I told him to go easy on me,” Boone said. “I didn’t want to look him in the eye — like Jedi mind trick on me or something.”

Hired to replace Joe Girardi, the former ESPN broadcaster managed the Yankees over the Tigers 3-1 in their spring training opener in Tampa.

Rasmus returns

Colby Rasmus is making a new start with the Baltimore Orioles after taking an eight-month break from baseball.

Rasmus signed a minor league contract with the Orioles this week, after abruptly leaving the Tampa Bay Rays in midseason. The contract is for $3 million if he makes the Orioles and contains up to $2 million in incentives.

The 31-year-old outfielder, who had a lingering hip injury last season, discussed some of the reasons for his departure.

Rasmus said, “My 8-year-old girl was in school, just had a boy who was 10 weeks old, so being able to spend time with them and keeping my wife feeling good through her pregnancy was important to me.”
