While rank outsiders Marc Leishman and John Senden have won both their pool games to be in contention to qualify for the round of 16 at the WGC Cadillac Match Play in San Francisco, their two highly-fancied Australian compatriots Jason Day and Adam Scott were unceremoniously beaten in both their games.
The latter two will now exit the tournament.
The new format has made this tournament very different – and very interesting.
For the first time not every round is sudden death, with 16 pools of four making sure the field plays for three days.
Leishman beat Justin Rose 3 and 2, then 4 and 3 over Ryan Moore, while Senden won at the 19th over Henrik Stenson, then toppled Bill Haas 4 and 3.
Defending champion Day went down 4 an 3 to Charley Hoffman, and repeated the scoreline against journeyman Brenden Grace.
Scott was thumped 5 and 4 by Francesco Molinari, then by a hole to unbeaten Paul Casey.
The 16 pool leaders play Saturday morning, the winners qualify for the quarter finals in the afternoon.
The semis will be decided on Sunday morning, with the final in the afternoon.
How the groups look after two rounds with world number two Jordan Spieth in white hot form, sinking seven birdies on each day with 10 successive one-putt greens today, all of them 12 feet or more.
Spieth is the man to beat.
Group 1

McIlroy and Horschel both unbeaten after two rounds, and play off tomorrow to advance.

Adam Scott. A one season wonder? What has he done with his talent since November 2013. I sincerely doubt that he will ever grace the winners Dias in a GS tournament or second tier event again. He appears to spend most of his time in the Caribbean and forgetting his day job is playing golf. This does not mean hitting balls into the ocean between nappy changes. What he needs to be doing is competing at least every two weeks against the "ENEMY". This is the only way that he will hold his edge and stand up under pressure & the clutch shot to the pin. I can only remember him playing in around five tournaments in 2015 and in these events he either folded on the weekend or did not make the weekend. The guy has as much talent, if not more, than Jason Day but zilch results in comparison in 2015. Even McIroy has a few off tournaments but is more often than not in the top ten, usually much higher. Adam needs to come to terms with the fact that one Green & Gold jacket is no substitute for competition. The quicker he accepts this the better for him Richard Egan.
