Matt Bettencourt and Peter Tomasulo shot 5-under par 67s to earn the surprising lead after the first round of the Texas Open on Thursday, holding off a field that includes world No. 2 Rory McIlroy.
Bettencourt made the tournament as an alternate. The former Reno-Tahoe Open winner needed only 25 putts, joining Tomasulo in holding off a group of four players — including three-time major winner Padraig Harrington — at 4 under.
Harrington and Billy Horschel shared the lead following the morning tee times, battling chilly and windy conditions. They were joined by Bryce Molder and Harris English at 4 under in the afternoon.
McIlroy, who entered the tournament as a final opportunity to prep for next week's Masters, opened with an even-par 72 and is tied for 45th.
