Sergio Garcia will bring his green jacket to Texas this week to defend his title at the AT&T Byron Nelson. Here's a look at a few early-round, marquee groupings at TPC Four Seasons Resort at Las Colinas in Irving (all times ET):
Koepka held the 54-hole lead here last year before succumbing to Garcia in a sudden-death playoff. He'll play the first two rounds alongside Dufner, who earned his second career victory at this event in 2012, and Poulter, who heads to Texas fresh off a runner-up finish at The Players Championship that locked up his status for next year.
