Palmer: The old Tiger will be back The tournament's namesake, Arnold Palmer, did not congratulate the winner as expected because of a health problem that led to his going to Dr. P. Phillips Hospital in Orlando. Alastair Johnston, chief operating officer of Arnold Palmer Enterprises, explained in a statement that the 83-year-old golf giant's blood pressure -- when checked 15 minutes before Woods wrapped up the contest -- was "at a level where the doctor involved suggested that he go immediately to get more intensive evaluation at the hospital." After his victory Sunday, Woods took to Twitter to express his joy and also send out well wishes to Palmer. Heading home now and I can't stop smiling. Thanks to Otown fans and everyone watching for all the love. Get well soon, Arnie," he wrote.
