To make room on the 40-man roster for Jimmy Rollins, the Phillies waived infielder Carlos Rivero. He was claimed by the Washington Nationals on Wednesday.
Rivero, 23, was acquired off waivers by the Phillies last winter. He hit .270 with 16 home runs mostly at double-A Reading with a brief stint at triple-A Lehigh Valley coming at the end of the season.
He was a shortstop in the Cleveland organization before the Phillies moved him to third base. He made 27 errors at third in 2011
In addition, the Phillies invited two more players -- infielder Hector Luna and outfielder Luis Montanez -- to spring training on minor-league deals.
