The Internationals threatened on Saturday, but the last hour was all US. We recap a wild afternoon highlighted by Si Woo Kim and Patrick Cantlay exchanging blows on the back nine in the dark. We talk about Weir's strategy, tomorrow's singles matches, highlights and lowlights of the day, and a ton more. We're also pumped to talk about our new partnership with The Stack System. Soly has been in the lab hunting speed gains, and the results have been astonishing. Hear all about it in the show, and visit www.thestacksystem.com and use code NLU for 10% off your bundle and starting hitting the ball farther. It's WILD how effective this has been.
