Otaegui and Wallace joint-leaders in Beijing
Adrian Otaegui joined Matt Wallace at the top of a crammed leaderboard on moving day at the China Open.
Wallace held a one-shot lead at the halfway mark in Beijing, but will head into his final round locked on 12 under with Spaniard Otaegui.
Otaegui signed for a five-under 67 on Saturday after reeling off five birdies in a row in a blemish-free third round at Topwin Golf and Country Club.
The world number 142 kept himself firmly in contention for a second European Tour title with birdies at the eighth and ninth holes before making another three gains in a row after the turn.
Wallace would have been out on his own but for a bogey at 17, where he also dropped a shot on Friday, which ensured he had to settle for a three-under 69.
The Englishman turned in 34 and a fourth birdie of the day at the 15th put him on 13 under, but his only dropped shot at the penultimate hole cost him the outright lead.
Alexander Bjork, Julien Guerrier and Jorge Campillo are just a shot off the pace, while Jinho Choi is among six players only two strokes adrift of the joint-leaders after a magnificent seven-under 65.
Defending champion Alexander Levy also carded a 65 to move to nine under, putting himself in contention for back-to-back titles following his Trophee Hassan II triumph last weekend.
