Nady had been sidelined since he strained his left hamstring Sept. 5, and though he said he wasn't sure if he could list himself as being 100 percent healthy, he assured that he was ready to play on an everyday basis.
"You just have to be smart if you hit a ball in the gap or something, try not to do something nuts or crazy," Nady said. "Each day you can build your stretch back and then monitor it."
The 33-year-old Nady had his contract purchased from Triple-A Fresno on Sept. 1 and had batted 4-for-12 before the injury.
"He's been around and knows how to play the game," manager Bruce Bochy said. "He was swinging well before he got hurt."
Nady's return coincides with Gregor Blanco's sore shoulder, which sidelined him Sunday. Bochy said the only way Blanco would appear in Monday's game would be as a pinch-runner.
"We're pretty confident that he's going to be fine in a couple days," Bochy said. "He's made a lot of progress from yesterday. He won't take batting practice and then we'll evaluate him tomorrow."
The time spent recovering from the injury allowed Nady, who started the season on the Nationals, the chance to get to know his new teammates a bit more as the club looks to head into postseason play.
"I've been playing against a lot of these guys for a long time, and sometimes you don't like playing against them," Nady said. "And then you get a teammate, and then it's like, 'This guy's not a bad guy at all.'"
