English golfer Matt Wallace carded a 5-under 67 at Fairmont St Andrews to join Adrian Otaegui in the Scottish Championship lead on Friday.
Wallace took advantage of favorable morning conditions by making six birdies and a single bogey to reach 12 under par.
He went into the clubhouse with a two-shot lead, but overnight leader Otaegui fought hard in his afternoon round, improving his fortunes on his back nine. There, the Spaniard made four birdies and a bogey to follow up his opening round of 62 with a 70.
Aaron Rai, the winner of the Scottish Open two weeks ago, made two eagles in his first six holes and was one shot back.
