Hernandez replaced in second inning
Hernandez didn't allow a hit, but he walked three. Juan Padilla replaced him to start the third.
El Duque is the latest Yankees starter with an injury. Mike Mussina and Kevin Brown are already on the disabled list, and Tanyon Sturtze has an injured right pinky that will keep him from starting Thursday against Baltimore. Jose Contreras with pitch on three days' rest against the Orioles.
Brown has been sidelined since June 9 with a lower back spasm and an intestinal parasite, but could return Friday if a bullpen session goes well on Wednesday.
Hernandez is 2-0 with a 2.37 ERA in four starts, including Tuesday.
