British Open: Tee times, pairings, TV, streaming and more for Sunday's final round

The final round of the British Open gets going early Sunday, the result of a rough forecast for the afternoon and evening that expects to see heavy rain and winds hit Royal Portrush. While the action gets going around 2:32 a.m. ET (!), the leaders are expected to tee off around 8:47 a.m. ET (1:47 p.m. local time).
That final group consists of Shane Lowry, an Irishman, and Tommy Fleetwood, an Englishman. Lowry dazzled the supportive Northern Ireland crowd Saturday as he carded an 8-under 63 to take a four-shot lead over Fleetwood (who's at 12 under).
Lowry has been in this position before: at the 2016 U.S. Open. In that tournament he saw his four-shot lead in the final round evaporate when he posted a 76 to finish tied for seond behind Dustin Johnson.
One other big name lurking? Brooks Koepka, who sits 7 shots back at 9 under.
