NEW YORK (AP) _ The Philadelphia Phillies placed third baseman David Bell on the 15-day disabled list with a strained lower back after Friday night's game against the New York Mets.

Infielder Tyler Houston was activated from the disabled list to take Bell's place on the roster.

Bell, hitting just .198 with four homers and 37 RBIs in his first season with the Phillies, has been bothered by a sore hip, as well. He thinks the soreness in his back and hip are related, and said he'd see a doctor within the next few days.

``I just need to do everything I can to get better,'' Bell said. ``Whatever it is, it'll get better.''

Bell was replaced at third base by Tomas Perez to start the third inning of Thursday night's win at New York and didn't play Friday night. He said the pain in his hip developed about 10 days ago, and he also missed five days in April with back spasms.

Houston has been sidelined since May 14 with a broken left middle finger. He was injured while trying to bunt as a pinch hitter against Arizona on May 13. He was hitting .333 with one homer and seven RBIs in 36 at-bats, and was leading NL pinch hitters with a .438 average (7-for-16).
