Rob Mackowiak from the Chronology

Dec 8, 2005 - The White Sox trade P Damaso Marte to the Pirates for utility man Rob Mackowiak.

May 28, 2004 - Rob Mackowiak of the Pittsburgh Pirates has a day to remember. In the morning‚ his wife gives birth to his first son. Later that day‚ his walk-off grand slam in the 9th inning offsets an eight-inning grand slam by Michael Barrett and gives the Pirates a 9-5 win over the Chicago Cubs in the first game of a doubleheader. In the second game‚ Mackowiak hits a 2-run HR in the bottom of the 9th to tie the score. Pittsburgh goes on to win the game in the 10th‚ 5-4‚ on Craig Wilson's homer. It is just the 3rd time in history that a doubleheader has ended with two walkoff homers: the other times were July 25‚ 1967 and May 12‚ 1962.
