Nationals infielder Anthony Rendon has been playing third during camp, according to The Washington Post.
Rendon has also been playing second base, but is taking ground balls at third. There's a chance the team will occasionally use Ryan Zimmerman at first, which would allow Rendon to see more time at his natural position. If Zimmerman gets hurt, the team would be covered with Rendon at third and Danny Espinosa at second.
Rendon hit .265/.329/.396 in 351 at-bats during his rookie season.
