This is why you hit all those range balls, this is why you roll all those practice putts, this is why you get up before dawn and get home after dark... it's playoff time!

The PGA Tour postseason is under way this weekend, and kicking off the first round of the FedExCup Playoffs is The Barclays.

Only the top 125 performers from the 2013 regular season earned a spot in the playoff opener, and the field will continue to shrink as the race for the FedExCup continues.

And among this elite class of 125, 79 players in the field will look down confidently at the Titleist script on their Pro V1 or Pro V1x golf ball. That's nearly five times the nearest competitor with 16, and more than all other competitors combined.

Titleist is also the top choice in the irons (29); sand, lob and approach wedge (116); and putter (39) categories.

Be sure to check out the video above to go inside the ropes with Team Titleist at Liberty National, as we snapped a few photos and videos while Titleist Brand Ambassadors Adam Scott, Bill Haas, Jason Dufner, Webb Simpson, Charley Hoffman, and Jimmy Walker (to name a few) prepared for the postseason.

Play well this weekend! #TeamTitleist
