The tee times and groups are set for the first two rounds of the 145th Open Championship at Royal Troon this week. There are some great ones too. The highlights are probably as follows:

Jordan Spieth, Justin Rose and Shane Lowry

Rickie Fowler, Jason Day and Danny Willett

Rory McIlroy, Bubba Watson and Hideki Matsuyama

These groups teed off before 4 am central time this morning.

US Open wininer Dustin Johnson tees off just after 8 am this morning with Martin Kaymer and Russell Knox.

Phil Mickelson is paired with Lee Westwood and Ernie Els. That group tee's off around 7:30 am.
