Task: Question Generation
Input (English): Despite losing fan favorite Grace to free agency, and the lack of production from newcomer Todd Hundley, skipper Don Baylor's Cubs put together a good season in 2001. The season started with Mack Newton being brought in to preach "positive thinking." One of the biggest stories of the season transpired as the club made a midseason deal for Fred McGriff, which was drawn out for nearly a month as McGriff debated waiving his no-trade clause, as the Cubs led the wild card race by 2.5 games in early September. That run died when Preston Wilson hit a three run walk off homer off of closer Tom "Flash" Gordon, which halted the team's momentum. The team was unable to make another serious charge, and finished at 88–74, five games behind both Houston and St. Louis, who tied for first. Sosa had perhaps his finest season and Jon Lieber led the staff with a 20 win season.
Output (English): Who hit a three run walk off homer off of closer Tom "Flash" Gordon?
