Muzzy Donohue shoots 63 to make the cut in his PGA Tour debut.

Donohue rebounded from an opening 73 with an eight-under 63 at the 3M Open. The 25-year-old Minnesota native reached six under, two strokes outside the top 10 entering the weekend.

Donohue earned his sponsor exemption by winning the Minnesota Open earlier in July. He is honoring his grandmother, who died Monday, with a custom ball marker.
