PHOENIX -- Jake Peavy, Team USA's starter in Tuesday's opening game of the tournament against Mexico at Chase Field, said Saturday that he recently was treated for slight tears in the retinas of both eyes.

The San Diego Padres 24-year-old ace right-hander is acutely nearsighted and the diagnosis was determined during a recent eye exam. Surgery was not deemed necessary, and at this point, he said he's being treated with eye drops.

"I have a hole in my retina," Peavy said during Saturday's second day of workouts for the American team. "Actually, I have holes in both of my retinas. There's some slight tearing in there and a little scar tissue. They're treating it with the drops and should be fine."

Peavy wears contact lenses and said he is not able because of his condition to endure any sort of corrective vision surgery.

Team USA manager Buck Martinez has tabbed Peavy as the starter for not only Game 1 of the first round against Mexico at Chase Field on Tuesday, but for Game 1 of the second round May 12 in Anaheim and the semifinals at Peavy's hometown PETCO Park on March 18 if the U.S. gets there.

In his four big-league seasons, all with the Padres, Peavy has become one of baseball's top young starters. He's 46-31 with a 3.33 earned run average in 106 starts. In 2004, he led the National League with a 2.27 ERA, and last season led the senior circuit with 216 strikeouts.

"That's just the way it is," Peavy said about his eyesight. "I've been living with that my whole life."

Sunday's lineup: After the workout, Martinez released his lineup for Sunday's tuneup against the San Francisco Giants at Scottsdale Stadium: Johnny Damon (LF), Derek Jeter (SS), Ken Griffey Jr. (CF), Mark Teixeira (1B), Chipper Jones (3B), Brian Schneider (DH), Michael Barrett (C), Randy Winn (RF), Chase Utley (2B) and Rogers Clemens starting, with Al Leiter and all 10 relievers behind him in the 10-inning game.

Those 10 innings: The Giants have agreed to do it, but since they are sending a split-squad to Mesa for a concurrent game with the Chicago Cubs, may not have enough pitchers to go 10 innings. Giants manager Felipe Alou said he would use some Minor Leaguers to accommodate the Americans. The Giants are also keeping most of their heavy hitters in Scottsdale. "Out of respect to the U.S.," Alou said. "We'll send all of our kids over to Mesa. Myself and the Major League coaching staff will stay in Scottsdale." The Giants manpower problem is complicated by the fact that Winn, Pedro Feliz, Moises Alou and Omar Vizquel are all with their respective teams for the Classic.

Buck on the lineup: "We'd like to try and get as many guys as we can in the game," he said. "If we can, we'll get everybody in the game. There are some guys who haven't had any at-bats. Brian Schneider hasn't had any at-bats. In the exhibition game, its going to be a little more relaxed, so he's the DH. Randy starting in right field in the Giants ballpark is a little honor he deserves. Alex Rodriguez will pick up Chipper. We're going to go with at-bats rather than innings. I want everybody to get two or three at-bats. They're all healthy."

Stars and stripes: Martinez said the three catchers will each start a first-round game, and he has already paired one with a starting pitcher and asked them to work together in practice: Clemens with Barrett in both the tuneup vs. the Giants and Game 3 Friday against South Africa, Jason Varitek with Game 2 starter Dontrelle Willis vs. Canada and Schneider with Peavy in Tuesday's Mexico tilt. ... First, Johnny Damon has moved right in from Red Sox Nation to the Yankees clubhouse. Now, he's feeling comfortable among his teammates on Team USA. "Guys who are well known around the league are able to get along with everyone," Damon said. "There's a lot of talent, potential Hall of Famers. Guys who have been around and represented the game very well." No, Damon hasn't grown back his signature beard now that he's out of Yankees camp for perhaps as long as 17 days. ... Martinez said he won't necessarily be guided by the 65-pitch limit for starters in the first round. It may be three innings and out, no matter how many pitches one of his starters throw. "If Jake blows through three innings and throws 35 pitches, because of the way we've put together this team, we can tell him, 'Thanks, that's all we needed from you.' He'll feel very good about his outing. He'll have gotten his work in. The Padres won't be concerned. And now we can get our relievers in the game."
