Veteran striker Robbie Winters hit the only goal of the game as Peterhead climbed to third in tThird Division with victory over struggling Clyde.
Clyde striker Kevin Watt's drilled effort was brilliantly denied by Blue Toon goalkeeper Marc McCallum before Ryan Strachan tested Jamie Barclay from 25 yards at the other end.
Winters then put Jim McInally's side in front in the final minute of the first half as he nodded David Cox's cross into the bottom left-hand corner from 12 yards.
Scott McLaughlin came close to doubling the lead but his powerfully-struck drive from 20 yards whistled over the crossbar.
Clyde failed to create any clear-cut chances of an equaliser in the closing stages as they slipped to a fourth successive loss and seven games without a league win.
