Yankees' lefthander Andy Pettitte will make his first start of the season Saturday after being activated from the 15-day disabled list, as reported by Yahoo.com. The 35-year-old Pettitte went on the DL on March 29 with back spasms that bothered him during the last two weeks of spring training. The move was retroactive to March 21, making him eligible to pitch during the Yankees? first homestand.
