Houston ? Houston pitcher Roy Oswalt and Detroit outfielder Magglio Ordonez were added to the All-Star rosters Friday, taking the place of injured Pedro Martinez and Manny Ramirez.

Ordonez will join Detroit teammates Ivan Rodriguez and Kenny Rogers at Tuesday night’s game at PNC Park. The surprising Tigers have the best record in the majors.

Ramirez, picked in fan voting to start in the AL outfield, has a sore right knee. Minus the Boston slugger, AL manager Ozzie Guillen gets to choose another starter.

Ordonez, on the All-Star team for the fifth time, is batting .307 with 15 home runs and 59 RBIs. Ramirez was hitting .310 with 24 homers and 65 RBIs.

Oswalt will make his second consecutive All-Star appearance and joins Lance Berkman as the only Astros on the NL squad. Oswalt pitched one inning in last year’s game in Detroit.

Martinez missed his start Monday because of a sore right hip and the New York Mets placed him on the 15-day disabled list.

Houston’s Phil Garner, the NL manager, asked Oswalt to join the team after learning of Martinez’s injury Thursday.

Oswalt (6-5) ranks sixth in the NL with a 3.10 earned-run average. He’s thrown complete games in his last two starts and lost both, the first Astros pitcher to pull off the dubious double since J.R. Richard did it in 1979.
