Rory McIlroy is the headline act in San Antonio this week as former Open champion Ben Curtis defends his Valero Texas Open title.
McIlroy has added the event to his schedule to get in some much-needed extra competitive golf ahead of next week's Masters.
The world No 2 looked to have turned a corner with a top-10 finish at the WGC-Cadillac Championship, but his erratic form returned last week in Houston where he narrowly made the halfway cut.
A tie for 45th place on four under - 12 shots behind winner DA Points - was hardly encouraging ahead of the Masters, and he joins the likes of Charl Schwartzel, Matt Kuchar and Ian Poulter in a decent San Antonio field.
McIlroy the favourite
Despite his struggles, McIlroy lines up as Sky Bet's 8/1 favourite ahead of 9/1 chance Schwartzel, who is also making his debut in the event, but the top two are likely to be upstaged by the consistent Matt Kuchar.
The affable American claimed a popular victory at the WGC-Accenture Match Play in February, and he earned a share of 13th here last season despite an uncharacteristic second-round 76.
Kuchar is offered at 11/1, while Charley Hoffman finished on the same score as Kuchar last year and looked in decent touch at Redstone following a barren couple of months.
Hoffman and Peter Hanson should attract interest at 40/1, while Bud Cauley finished strongly here 12 months ago and could provide each-way rewards at 50/1.
