Medrano, a veteran minor league infielder, is hitting just .174 this spring, but two of his four hits have been game winners.
Pat Burrell provided the offense earlier in the game with a three-run homerun off former Phillie Felix Rodriguez in the bottom of the sixth. The homerun was Burrell's fourth of the spring and he is now hitting .357 on the spring. Jason Michaels hit his first homerun of the spring off Carl Pavano in the second.
Bobby Abreu finished the day with a double and two singles, scoring one run and driving in another.
Jon Lieber, who will be the Phillies opening day starter, threw six innings, giving up three earned runs. Tim Worrell gave up a solo homerun to Felix Escalona that tied the game and sent the game into extra innings.
