Atlanta Braves starting catcher Sean Murphy will miss the start of the season with a rib injury.

The one-time All-Star and Gold Glove winner is expected to be sidelined for four to six weeks with a cracked rib on his left side, the team said Monday.

Top prospect Drake Baldwin is a candidate to replace Murphy behind the plate for Opening Day at San Diego on March 27.

Murphy, 30, struggled last season after an abdominal strain on Opening Day and batted .193 with 10 homers and 25 RBIs in 72 games with the Braves in 2024. He is a career .233 hitter with 77 homers and 240 RBIs in 510 games with the then-Oakland Athletics (2019-22) and the Braves.

The Braves declined Travis d’Arnaud‘s $8 million option during the offseason, clearing the path for Murphy to be the No. 1 catcher. D’Arnaud signed with the Los Angeles Angels.

Chadwick Tromp is the only other catcher on the Atlanta 40-man roster. He hit .250 in 19 games in 2024.

Murphy made the National League All-Star team in 2023 and collected a Gold Glove at catcher with the Athletics in 2021.

SURPRISE, Ariz. — Mike Moustakas will retire with Kansas City after spending 13 years in the majors and winning the World Series with the Royals in 2015.

The Royals announced Moustakas’ retirement Monday. The 36-year-old infielder will sign a one-day contract with his first big league team on May 31, and he will be honored before Kansas City’s home game against Detroit that day.

Moustakas hit .247 with 215 homers and 683 RBIs in 1,427 games, also playing for Milwaukee, Cincinnati, Colorado and the Los Angeles Angels. The three-time All-Star appeared in his last major league game with the Angels on Sept. 30, 2023.

Moustakas was the No. 2 pick in the 2007 amateur draft. He broke into the majors with Kansas City in 2011.

He became a key performer for the Royals during a memorable stretch for the franchise. He hit .284 with 22 homers and 82 RBIs in 147 games in 2015, helping the team win the AL Central. Then he drove in eight runs in the postseason as the Royals won the World Series for the first time since 1985.

Moustakas bashed a career-high 38 homers for Kansas City in 2017. He set a career best with 95 RBIs while playing for the Royals and Brewers in 2018.

WEST PALM BEACH, Fla. — The Houston Astros are planning to play Jose Altuve mostly in left field this season, manager Joe Espada told the Houston Chronicle on Monday.

A nine-time All-Star, three-time batting champion and the 2017 AL MVP, Altuve has played all but two of his 1,767 major league games at second base. He won the Gold Glove in 2015, and in 2020, he led the American League with the fewest errors, with four.

“Right now the plan is for him to play the majority of his games in left field,” Espada said, adding that moving Altuve “back and forth is something that I am going to avoid.”

The idea of moving Altuve to left was first broached when the team was looking to keep third baseman Alex Bregman, who wound up signing with the Boston Red Sox. If Bregman had returned to Houston, it might have forced newly acquired Isaac Paredes to shift to second base and Altuve to the outfield.

“Whatever I have to do for [Bregman] to stay, I’m willing to do it,” Altuve said at the team’s FanFest in January.
