PHILADELPHIA (AP) — The Philadelphia Phillies have placed All-Star catcher Carlos Ruiz on the disabled list because he has plantar fasciitis in his left foot.

An MRI revealed Ruiz has a partial tear. He is expected to miss four to six weeks. Infielder Hector Luna was called up from Triple-A Lehigh Valley before Saturday’s game against Arizona.

Ruiz was hitting .335 with 14 homers and 58 RBIs. All were career highs for the 33-year-old veteran.

Luna batted .246 with two homers and 10 RBIs in 26 games for Philadelphia previously this season.
