Catcher Johnny Estrada passed his physical on Thursday and has finalized a one-year deal with the Nationals worth $1.25 million, according to the Washington Post Estrada agreed to the deal earlier this week shortly after Paul Lo Duca went on the disabled list. "Going into the offseason, we really felt like we wanted to improve offensively at catcher and in center field," General Manager Jim Bowden told the Post. "We feel like we've done that."
