Izturis has played with several of his new teammates, from Mark DeRosa and Michael Gonzalez to Edwin Jackson and Jayson Werth, at various points during his 12-year Major League career.
"I've played with those guys," said Izturis, who will wear No. 6 with the Nationals. "To come in here, you feel at home."
The veteran infielder said he was "surprised and excited" when he found out Washington had claimed him off waivers, and he'll fill whatever role manager Davey Johnson puts him in. More than anything, he enjoyed the idea of going from a struggling Brewers club (49-59) to the first-place Nationals.
"It was great," Izturis said. "They're in first place for a reason. I think they want to win, and that's the bottom line. Win games. It's what you're here for."
