CLEVELAND (AP) - Sunday began on a high note for Michael Bourn and the Cleveland Indians.
The day ended with a 3-1 loss to the Chicago White Sox that could affect the team beyond one game.
Bourn, who homered on White Sox starter Jake Peavy's first pitch to account for Cleveland's only run, could miss several games after receiving five stitches to close a laceration on his right index finger.
Bourn was injured in the eighth inning when his hand was stepped on by pitcher Matt Thornton while making a headfirst slide into first base. He had hit a slow grounder that was fielded by first baseman Adam Dunn, who tossed to Thornton. He was safe, but remained on one knee for a few moments and was examined by manager Terry Francona and a trainer before being removed.
The outfielder, who signed a four-year, $48 million contract with the Indians in February, says he will not be able to play until the stitches are removed.
"We'll wait for it to heal," he said. "No ligaments were messed up. No joints were messed up. I knew something was wrong. I felt pain when I got up. I'll probably be in a little pain for the next day or two, but other than that I should be fine."
Bourn said he doubted he'd play Tuesday when the Indians open a three-game series with Boston at Progressive Field. He hasn't been given a timetable by the team's medical staff on when he will return.
"We'll see how long it takes," he said. "It shouldn't take too long from what (the doctor) said. I'll just take it day by day. You can't tell right now because it's real fresh."
Bourn said he had a similar injury earlier in his career, which also occurred when he dove headfirst trying to beat out a ground ball.
"I was just trying to get to the bag before he did," Bourn said.
Bourn, who went 3-for-4 on Sunday, is batting .333 in 10 games. His home run was a line drive that landed in Chicago's bullpen, but it might have served to fire up Peavy, who struck out 11 in seven innings and retired 12 straight at one point.
"I got him going after I hit the bomb," Bourn said. "He was tough on us."
Francona gave full credit to Peavy, who improved to 4-0 in five career starts against Cleveland.
"Bournie kind of ambushed him the first pitch of the game, but after that we didn't have many opportunities to score until late," Francona said. "He's just a really good veteran pitcher."
Indians starter Brett Myers turned in his best outing of the young season. The right-hander took a four-hit shutout into the sixth, but Paul Konerko's two-run homer gave Chicago the lead for good as the White Sox broke a five-game losing streak and won for the first time on the road this season.
Myers allowed 14 earned runs, including seven homers, in 10 1-3 innings in his first two appearances, but held the White Sox to four hits through five.
"I'm really encouraged," he said. "I felt comfortable. I was able to get the ball down. One pitch cost me."
After Jeff Keppinger reached on third baseman Lonnie Chisenhall's error to begin the sixth, Alex Rios bounced into a double play. Dunn walked and Konerko hit a 3-1 pitch into the bleachers.
The home run was the second of the season for Konerko, who has hit 30 or more home runs seven times in his career.
"I feel like I'm climbing a little bit," he said. "I feel better. I wouldn't say I'm clicking on all cylinders, but just trying to grind through here."
Konerko has 16 career home runs and 75 RBIs at Progressive Field. He leads active players with 47 homers and 173 RBIs against the Indians.
Addison Reed pitched the ninth for his fourth save, retiring Jason Giambi with a runner on to end the game. Giambi made his first appearance for the Indians, starting as the designated hitter and going hitless in four at-bats. He began the season on the disabled list with a strained back and was activated Friday.
The Indians again played without second baseman Jason Kipnis (sore left elbow) and catcher Carlos Santana (bruised left thumb) in the starting lineup. Kipnis was also out on Saturday while Santana, who walked as a pinch-hitter in the ninth, had missed three straight games.
The Indians are off Monday. Francona will face the Red Sox, the team he managed for eight seasons, for the first time since being replaced following the 2011 season when Boston collapsed down the stretch. Francona led the Red Sox to World Series titles in 2004 and 2007.
