SCOTTSDALE, Ariz. (AP) — Kyle Seager will be absent next week when the Seattle Mariners play the major league opener in Japan. Mike Foltynewicz will miss opening day for Atlanta, too.

Dodgers ace Clayton Kershaw, meanwhile, is on the mend.

The Mariners said Monday that Seager needs surgery on his left hand, sidelining the third baseman through at least April. The former All-Star and Gold Glove winner rolled his glove going for a grounder in a spring training game last week.

Seattle is likely to move first baseman Ryon Healy across the diamond to third. The Mariners and Oakland begin the regular season on March 20 in Tokyo.

The Braves had hoped Foltynewicz could start on March 28 when the NL East champions open at Philadelphia, but a sore elbow has slowed the All-Star righty.

Foltynewicz has yet to make an appearance in an exhibition game because of discomfort that began about two weeks ago.

“We’re just trying to figure out at what point do we get him up to five innings?” general manager Alex Anthopoulos said. “He’s not that far removed from throwing (off the mound), but we still want to be careful how we build him up.”

With Foltynewicz out, the Braves could go with Julio Teheran on opening day for the sixth year in a row. Lefty Sean Newcomb is another possibility.

Kershaw threw his first bullpen since Feb. 20, an all-fastball session of 20 pitches. The three-time NL Cy Young Award winner has been slowed by left shoulder discomfort.

“Good day, good step forward, for sure, and just kind of keep going forward from here,” Kershaw said.

GIANTS 4, DODGERS 1

Chris Stratton made his fourth start for San Francisco, pitching four innings and allowing one run. Giants catching prospect Joey Bart hit a three-run double with two outs in the ninth.
