It's a busy Sunday for racing as F1 and NASCAR Cup Series are both on track. NASCAR heads to Homestead-Miami for the Dixie Vodka 400 in the Round of 8 of the NASCAR Playoffs. Meanwhile, Formula 1 is in the Lone Star state in Austin, Texas for the United States Grand Prix at Circuit of the Americas. That gives us plenty of options for the PrizePicks Power Play of the Day this week and we'll be dipping into both. Sebastian Vettel and Pierre Gasly bring the F1 picks while Daniel Suarez, John Hunter Nemechek, and Noah Gragson are the best picks for the Dixie Vodka 400. Check out the NASCAR and F1 Playbooks and the NASCAR Projections for more analysis for each race.
