Keith Anderson, Tim McGraw, the Warren Brothers, Lance Miller and ESPN's Baseball Tonight host John Kruk will all lend their star power this weekend to Stepping Up to the Plate — a three-day youth baseball tournament to benefit the Tug McGraw Foundation, a nonprofit organization that improves the quality of life for adults and children living with brain tumors.

Anderson, who lost his mother to brain cancer last year, will throw out the first pitch today (Friday, May 1).
