World number one Justin Rose missed the cut at the Saudi International, while American Dustin Johnson produced a 61 - the lowest round of his career - to hold a three-shot lead after two days.
Rose followed up his opening round 70 with a two-over 72 as he missed the cut for only the second time in 36 events.
World number three Johnson set a new course record with an eagle and seven birdies in his bogey-free 61.
South African Zander Lombard is tied for second with China's Li Haotong.
England's Chris Paisley is tied sixth on six under, five shots behind Johnson, with Ian Poulter a shot further back on five under.
Day one leader Thomas Pieters of Belgium had a day to forget as he followed up his 63 on Thursday with a four-over 74 on Friday to drop down to tied 18th.
"The mistakes I made were due to trying to chase the cut and that doesn't happen if I had putted a bit better the first day," said Rose.
"I actually played really nicely on day one. Today I felt not as good, but the mistakes were more because I was behind the eight-ball trying to get into the tournament."
Johnson, the 2016 US Open champion, said: "I was just trying to keep getting my score lower and lower.
"It was really good. Obviously you always have fun when you're playing well, but I did a lot of the same things I did yesterday. The greens rolled a little bit better today."
The Saudi International has attracted a top-class field despite scrutiny over the country's human rights record.
