Outfielder Eric Davis has colon cancer, for which he underwent surgery last week.
The Baltimore Orioles said Tuesday that Davis' disease appears to be confined to the colon and he is being evaluated for possible chemotherapy treatment.
"Eric does have cancer of the colon, carcinoma of the colon as we call it. The surgery was successful," Dr. Keith Lillemoe, a Johns Hopkins doctor treating Davis, said at a news conference.
"The prognosis really depends on the state at which it is operated on. I'd say he has a favorable prognosis; nothing is 100 percent. ... We're very optimistic about his prognosis."
Lillemoe said he would recommend chemotherapy for the 35-year-old Davis, but said he did not see any reason he could not play baseball again.
The 35-year-old Davis, in a statement, said, "I am feeling well and looking forward to making a complete recovery. ... I hope to be back on the playing field as soon as I possibly can."
JAHA OUT: The Milwaukee Brewers' feeble offense was jolted once more Tuesday with word that slugger John Jaha will miss the rest of the season following surgery on his left shoulder.
Jaha, Milwaukee's only power hitter, had hoped the operation by orthopedic specialist Frank Jobe in Los Angeles on Tuesday morning would reveal only a frayed labrum - the cartilage of the glenoid cavity in the front of the shoulder - and that he'd miss no more than three weeks.
"The entire labrum was pulled off and they had to put two staples in to reattach it," manager Phil Garner said. "You're looking at three months. Essentially, he's out for the season."
WILLIAMS DISABLED: Yankees center fielder Bernie Williams was placed on the 15-day disabled list Tuesday night with a strained left hamstring just before the second game of the club's Subway Series against the Mets.
Williams, second on the club with a .317 batting average and 50 RBI, was injured running to first base in his final at-bat Sunday in a doubleheader at Florida.
With Williams out, the Yankees started Chad Curtis in center field. Curtis, acquired in a June 9 trade with Cleveland, was 2-for-6 with two doubles and three runs scored in his first three games with New York. Curtis is batting .205 with three homers and five RBI in 30 games this season.
New York manager Joe Torre had hoped Williams would only miss the series with the Mets and would be ready when the club played in Cleveland this weekend. Torre had hesitated to use Williams as a pinch-hitter against the Mets for fear that Williams might worsen the injury.
After an examination, Williams' injury was found to be deeper in the muscle than originally believed, and the Yankees decided it was best to place him on the DL.
Outfielder Scott Pose was recalled from Triple-A Columbus to fill Williams' roster spot. Pose batted .192 (5-for-26) with three RBI in five starts during his first stint with the Yankees.
