Alex Bregman couldn’t hold back the smile when he was asked who might have had the biggest impact on his decision to sign with the Red Sox.

“My favorite player, Dustin Pedroia,” Bregman said of the club’s former second baseman and two-time World Series champion.

“He reached out a few times this offseason and talked about how special it was to be a part of the Boston Red Sox,” Bregman said Sunday. “It was really cool to be able to talk to him as well as so many other former players here in Boston and current players on the team as well.”

A day after Bregman’s $120 million, three-year contract was announced, he sat at a 25-minute news conference between his agent, Scott Boras, and Boston chief baseball officer Craig Breslow. Manager Alex Cora, who gave Bregman a hug after the infielder was handed his No. 2 jersey, also was at the table, along with team president Sam Kennedy.

Breslow and Cora wouldn’t say whether Bregman would move to play second base, Pedroia’s position, or remain at third — a position manned by Rafael Devers since July 2017.

A few players, Jarren Duran and Rob Refsnyder among them, and coaches stood behind the seated reporters to listen.

Bregman gets a $5 million signing bonus, a $35 million salary this season and $40 million in each of the following two years, with some of the money deferred, and he can opt out after the 2025 and 2026 seasons to become a free agent again.

Asked why he agreed to the shorter contract with opt outs, he leaned forward to the microphone in front of him and replied: “I just think I believe in my abilities.”

Originally selected by Boston in the 29th round of the 2012 amateur draft, Bregman attended LSU before the Astros picked him second overall in 2015. His family history with the Red Sox goes back further.

“My dad grew up sitting on Ted Williams’ lap,” he said.

ARENADO BACK

Cardinals third baseman Nolan Arenado reported to spring training on Sunday, 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.”
