Though Anthony Rendon is out of the lineup for the first game of the Nationals’ showdown series with the Giants, they will not be without him much longer.

Manager Matt Williams said Rendon’s right hand remains affected by the ball that drilled him Friday night in San Diego, which held him out for the final half of Friday’s game as well as Saturday and Sunday. But the Nationals’ everyday third baseman will be available as a pinch hitter Monday night and will likely return Tuesday, Williams said.

“He’s good,” Williams said. “He’s a little bit sore still. He hit today. He’s a lot better today than he was yesterday. I think one more day, he’ll be ready to go tomorrow. Still a little sore, though.”

Rendon took batting practice Sunday morning in an effort to test his hand but said he felt sore afterward.

Rendon, who turned 24 Friday, is hitting .272/.328/.470 with nine homers. Before he got hurt, Rendon had hit four homers in six games.

Kevin Frandsen has taken Rendon’s place at both third base and second in the batting order.
