The Canadian lefty sat 31st after firing a 1-over 73 at the Aloha Course on Friday, leaving him five shots behind leader Eduardo De La Riva.
It was the first cut made in over a year for Weir, who has been hobbled elbow and wrist injuries the past couple seasons. He had surgery to repair the extensor tendon in his right elbow in August and seems to have found some form during his 2012 debut on the European Tour.
On Friday, Weir mixed in three birdies with four bogeys to secure a tee time for the final two rounds. The native of Bright's Grove, Ont., plans to play more events in Europe this season after losing full-time playing privileges on the PGA Tour.
De La Riva is ranked 610th in the world and shot a 3-under 69 on Friday to take a one-stroke lead.
"I am very pleased with my birdie on 18, which is a challenging hole," he said. "I took a five-wood and four-iron over the water. I played well off the tee, but the key today were my shots to the green from 100 to 150 yards."
Tournament host Miguel Angel Jimenez shot a 68 to join Spain's Pablo Larrazabal (69), Italy's Matteo Manassero (73), Ireland's Damien McGrane and England's Tommy Fleetwood (69) at 7 under. Jimenez, a two-time Andalucia Open winner, is using the tournament as a final warmup before the Masters.
"I am only one shot behind the leader and it will be nice to be there in front on Sunday," Jimenez said. "I have played a lot of golf recently, competing in the two WGC events in America, so this will be my last event before Augusta. But this week has been very tough and very busy for me helping organize the event and while I have a lot of good people around me it always takes me forever to go from point A to B."
Manassero, three strokes ahead after match the course record with a first-round 64, played the first 12 holes in 3 over. He birdied Nos. 15 and 18.
The 18-year-old Manassero played alongside Jimenez.
"I talked a lot with Miguel about age difference, as he is 30 years older than me," Manassero said. "But I love playing with him because I learn a lot from his experience."
