AT&T PARK — On Wednesday afternoon, as Eduardo Núñez sat in front of his locker in the San Francisco Giants’ clubhouse, the third baseman was his usual upbeat self.

The trouble for the Giants is that neither Núñez nor his boss — manager Bruce Bochy — seem to know when his strained right hamstring will allow him to return to the lineup.

“I’ll try to play the last series,” Núñez said. “I’ll see how I feel. That’s the hope — [either] Friday or Saturday. Hopefully that series. Everything is going well. So, that’s the plan.”

The Los Angeles Dodgers arrive at AT&T Park on Friday for the final three games of the regular season, but Bochy didn’t sound overly confident that Núñez would take the field for the last set.

“It’s going to be questionable this weekend,” Bochy said. “Each day I’ll get better information [about] where he’s at. I’m hoping he’s going to be able to go, but I just think it’s going to be questionable with where he’s at with that hamstring.”

Núñez has not yet been able to test his hamstring, which he strained on Sunday against the San Diego Padres, but Bochy said all the time he’s been spending in the trainer’s room is paying off.

“Now, with that said, after all the treatment, we did get a little better news that he’s closer to playing,” Bochy said.

Cueto ready for next start

Bochy confirmed that Johnny Cueto (groin strain) is “good to go” for Thursday’s finale against the Colorado Rockies.

The manager also brushed aside the idea of switching Jeff Samardzija and Cueto for the the final two games of the Rockies series. If he had, Cueto would have been available for a potential play-in game on Monday.

“No, no, no,” Bochy said. “He’s coming off a groin injury and threw a pen for the first time yesterday.”

Coaches stay mum about Saturday

The manager and his top lieutenant – pitching coach Dave Righetti – likely already know who’s starting on Saturday, but Bochy isn’t saying.

“Right now, it’s TBA and we’re going to keep it at that,” Bochy said.

The decision is down to Albert Suarez and Ty Blach, who both took batting practice with the starters before Wednesday’s game. The numbers say pitching the rookie Blach is the smart play, as the Dodgers own the worst OPS in the bigs against lefties.albert suarezBruce Bochyeduardo nunezJohnny Cuetokarl buscheckMLBSan Francisco Giantsty blach
