Marc Warren is the only Scot to make the cut at the US PGA Championship after a rain-interrupted second round of 73 at Whistling Straits.
Resuming play at even par after 13 holes, Warren dropped a further shot but that was good enough.
Martin Laird birdied the final hole for a 71 but a double-bogey at the 15th meant he missed out by a stroke on three over par for the tournament.
Five other Scots in the Wisconsin field failed to progress.
Australia's Matt Jones is the surprise halfway leader on 11 under par, with compatriot Jason Day two shots behind.
Russell Knox and Richie Ramsay were both four over after completing their second rounds, two ahead of Senior PGA champion Colin Montgomerie.
Stephen Gallacher's miserable run of form continued with back-to-back rounds of 76 for an eight over total and Steven Young followed a 77 with an 81.
Ramsay shot one of the best rounds on day two with a five-under 67, but his opening-round 81 ultimately put paid to his hopes.
