Mike Hampton joined Paul Byrd on the disabled list Saturday, another blow to the Atlanta Braves' starting rotation heading into the start of the season.
Hampton strained his right calf during a workout on a treadmill Friday night and Byrd has a sore elbow. That leaves the Braves to open with a rotation of Greg Maddux, Russ Ortiz, rookie Horacio Ramirez and Jason Marquis.
"I feel terrible because I want to get in here right away and get off to a good start and help this team," Hampton said. "That's kind of a wash now."
Hampton, who expects to be sidelined until mid-April, said he was 17 minutes into a 20-minute routine on the treadmill when he felt a sharp pain in his right calf.
"I knew exactly what it was when I did it," he said, adding he had the same injury two years ago before his first season with the Colorado Rockies.
Braves manager Bobby Cox will use a four-man rotation for the first week or so, hoping Byrd will be available by April 10. Byrd is eligible to come off the DL on April 5, Hampton on April 12.
"We've got it covered. We'll be all right," Cox said.
Also Saturday, the Cincinnati Reds announced former President Bush will fill in for his son and throw out the ceremonial first pitch Monday for the Reds' season opener.
The Reds invited the current president to officially open Great American Ball Park by throwing a pitch before the opener against the Pittsburgh Pirates. Chief operating officer John Allen said Saturday that the White House gave no reason for the switch.
Bush was invited before the invasion of Iraq, and the White House had delayed making a commitment to the game.
