LOS ANGELES — Former Pirates manager Jim Leyland, named Thursday to lead the U.S. team into the 2017 World Baseball Classic, should know that a battery of Madison Bumgarner and Buster Posey might not be a pipe dream.

No player will commit to a tournament 11 months away, but Bumgarner said Saturday that he would consider it after turning down a chance to pitch in the 2013 WBC. So would his regular catcher.

“I’m open to it,” Posey said.

That thought might rattle Giants fans who saw how the last WBC affected Ryan Vogelsong. After his 214-inning 2012, postseason included, he pitched in the 2013 WBC. Vogelsong then had a 1-4, 8.06 start to the 2013 regular season.

In fact, the length of the postseason played into Bumgarner’s decision to decline the 2013 invitation. He also preferred to spend that spring working on his pitching after a poor end to 2012.

“It’s such a tough spot because of the timing of it,” Bumgarner said. “I couldn’t make a decision on it now. I want to see how the year goes, but I’d love to do it. It’s a great opportunity. Not many people get to play major-league baseball. Even a smaller amount get to do that.”

Workout day: A day after committing two errors, including a costly muff that thwarted a double play in a four-run inning, Kelby Tomlinson and infield coach Ron Wotus took the field at Dodger Stadium for early work, including footwork, staying down on groundballs and how to use his hands.

“It’s something we planned whether he had a night like that or not,” said Wotus, who believes extra work is important for a youngster coming off the bench for the first time.

Shortstop Brandon Crawford talked to Tomlinson about remaining aggressive despite the errors.

“Everybody is uplifting,” Tomlinson said. “It’s frustrating at this point, but there’s a lot of season left and I still believe this team is going to win a lot of games and I’m going to be part of it. I’ve made errors before. They kind of come and go. I’ve got to keep my spirits up.”
