"Even though Pudge is playing very well, I feel like to develop Ramos along I have to play him more than every other day," Riggleman said.
Ramos, acquired in a trade with the Twins last season as Rodriguez's heir apparent, started his second straight game Wednesday night against the Braves and hit fifth in the lineup. He was batting .301 with two homers and seven RBIs in 23 games through Tuesday.
"We're trying to get Ramos into more two and three day in a row stuff," Riggleman said. "Wilson just plays better when he plays more."
The veteran Rodriguez has hit .214 in 16 games, with a homer and 10 RBIs. Both catchers had excelled behind the plate, throwing out 4 of 11 would-be basestealers.
When Rodriguez's Hall of Fame career comes to an end, Ramos will take over the Nationals' catching duties full time.
"As he becomes the No. 1 catcher, he's going to be like like [Brian] McCann over there [with the Braves] and play five or six games [in a row]," Riggleman said.
