Here's how to watch Phil, Tiger Saturday at the Masters before network coverage begins

The third round of the Masters is underway and while CBS' national coverage won't begin until 3 p.m., but fans watch a whole lot of golf before then.

Tiger Woods and Phil Mickelson began their rounds early Saturday and nearly every shot they take is being shown. Here's how to watch them, and much more, before Jim Nantz says "Hello, Friends" at 3 p.m.

If you have DirecTV, it will be airing bonus Masters coverage, including some content in a high resolution "4K" format that looks almost like it's in 3D (you have to have a 4K TV and 4K equipment to see it).

That coverage, minus the 4K part, is also available via a Masters app available for smartphones, tablets and home streaming boxes like the Apple TV, Amazon Firestick and Roku. You can also watch online at masters.com

The bonus coverage includes "Featured Groups", including Mickelson and Woods, in the morning wave. In the afternoon, fans call follow Dustin Johnson and Jordan Spieth and Rory McIlroy and Henrik Stenson, even while the network coverage is ongoing.

In addition, there is coverage of golfers coming through the Masters' famous "Amen Corner," a stretch running from the 11th through the 13th holes that has historically produced dramatic golf. Also included is coverage of holes 15 and 16, a 530-yard par 5 that often produces birdies and eagles, and No. 16, a 170-yard par 3 where Woods made one of the most famous chip-ins in golf history.
