First-Round Viewing Guide
Thursday's tee times stretch from 1:35 a.m. ET to 11:21 a.m. ET, so the leaderboard takes shape overnight for American audiences. Peacock carries the early stream from 1:30 a.m. to 4 a.m. ET before USA takes over from 4 a.m. through 3:30 p.m. ET. That long window gives Polymarket promo code ACTION users plenty of live markets to work with as names rise and fall.
The Expert Pick: Rory McIlroy to Lead Round 1
Action Network's Tony Sartori zeroes in on the first-round leader market, and his pick is Rory McIlroy at +2200 — a call that fits Royal Birkdale perfectly. The course puts a premium on accuracy, with narrow fairways and deep bunkers that punish anyone who misses, so hitting fairways and greens is essential. McIlroy's driving has trended the right way lately: he beat the field average off the tee in each of his last two starts, including a T7 at the Genesis Scottish Open, where he also grabbed a share of the first-round lead. Sartori notes McIlroy has led after Round 1 at this championship twice before, in 2010 and 2014, so another fast start is well within range.
McIlroy won't have it easy. Defending champion Scottie Scheffler is still the world's top-ranked player even after a rare missed cut, and hometown favorite Tommy Fleetwood will have all of Southport roaring behind him. That three-way tension is precisely why the first round is worth trading — and why the $50 from Polymarket promo code ACTION goes a long way.
