Several of the biggest names on the PGA Tour continued strong starts at the WGC-Dell Technologies Match Play on Thursday, but Bryson DeChambeau was not among them.

Jon Rahm, Dustin Johnson and Brooks Koepka have all enjoyed 2-0-0 starts in Austin as they aim to top their four-man groups and reach the weekend.

Yet DeChambeau had only been able to tie with 49-year-old Richard Bland – bidding to become the oldest professional to qualify for the Masters – on Wednesday, with even that result requiring a little luck.

Up against Lee Westwood on Thursday, DeChambeau knew he must improve but did not. Westwood finished 1 up to leave DeChambeau bottom of Group 9 with just half a point.

DeChambeau at least has the excuse he is struggling with a wrist injury; world number four Patrick Cantlay will do well to explain away his below-par performances.

Cantlay lost his narrow lead over Keith Mitchell late on Wednesday and was well off the pace when play resumed in round two, beaten 5 and 4 by Seamus Power.

That result tied the biggest of Thursday, with Rahm and Justin Thomas also 5 and 4 winners against Cameron Young and Marc Leishman respectively.

Nothing quite compared to Maverick McNealy's sensational 8 and 6 defeat of Joaquin Niemann from the previous day – and McNealy could only tie with Kevin Na on Thursday, despite twice being 3 up.

Elsewhere, at the Corales Puntacana Resort and Club Championship, the tournament got under way with Ben Martin moving to the top of the leaderboard with a six-under 66, enough for a one-stroke lead.
