Westwood was three shots behind overnight leaders McIlroy and Bjorn at the start of the round but closed the gap with three birdies in his first four holes. The third-ranked Englishman birdied the 13th for a share of the lead with Bjorn and led when the Dane bogeyed the 15th.
“I got off to a good start,” Westwood said. “The only time I dropped two shots was when I hit two poor drives on 6 into the left rough, got a heavy lie and at 8 hit it into the sand on right. Other than that, very solid and gave myself lots of birdie chances.”
Joining Cabrera-Bello at one back are Stephen Gallacher (68) and Marcel Siem (68). McIlroy, who struggled early, finished with 72 to trail Westwood by two shots. Bjorn is three behind the leader with 73.
Joining McIlroy are Martin Kaymer (70), former Augusta State golfer Scott Jamieson (70) and Joel Sjoholm (66). Bjorn is in a three-way tie for ninth with George Coetzee (69) and Ben Curtis (67).
CHAMPIONS TOUR: In Boca Raton, Fla., Corey Pavin and Peter Senior – both winless on the Champions Tour – share the lead after the second round of the Allianz Championship at Broken Sound Golf Club.
Pavin followed his opening 8-under-par 64 with 70 to match Senior at 10-under. Senior had 68.
Mark Calcavecchia and Bernhard Langer are a stroke back. Calcavecchia had 68, and Langer 69.
Pavin had a two-shot lead with two holes left, but bogeyed the 17th – his lone bogey of the day – and Senior birdied the 18th. Pavin is making his 35th career Champions Tour start, Senior his 48th.
Senior overcame a bogey on the par-5 first hole with five birdies on his last 13 holes. The Australian had a one-shot lead heading into the final round last year, but shot 77 and faded to 17th.
“I have more confidence than I did this time last year, because I’m playing better,” Senior said. “I know I’m close to winning.”
