A Mets spokesman said Fernandez will be in a cast for six weeks and will be sidelined for up to three months. Fernandez sustained a non-displaced fracture of the ulna bone.
Last season, Fernandez was 9-14 with a 3.46 ERA. He has a career mark of 78-59. Fernandez has allowed 6.64 hits per nine innings, second only in major-league history to Nolan Ryan's 6.54.
Frank Viola started the game and was hit hard as the Astros beat the Mets, 11-4. Viola has bone spurs in his elbow and there has been speculation he may require surgery.
"The entire day was just disappointing," Mets manager Bud Harrelson said.
Fernandez, who was injured in the fifth inning, had the wrist placed in a cast and a sling after X-rays showed a break about three inches above the wrist. He will not be able to resume throwing for at least nine weeks.
RF "I'm just real disappointed," Fernandez said. "It's not a real bad
break. It's still in place -- it's just shattered."

* REDS: Cincinnati has no plans to trade pitcher Jack Armstrong, who has been fined $2,500 since leaving camp in a contract dispute.
