Top-ranked Tiger Woods had a tougher time with a squirrel and a hand-slap routine swiped from a 1990s television show than anything Presidents Cup rivals offered in Thursday's four-ball matches.

US PGA Player of the Year Woods, a 14-time major champion, and Matt Kuchar, this year's WGC Match Play winner, routed Argentina's Angel Cabrera and Australian Marc Leishman 5 and 4 on day one at the biennial team golf showdown at Muirfield Village.

The day's most comical moment came at the expense of Woods when he was introduced by his girlfriend, US ski star Lindsey Vonn, to "Sammy", a squirrel who met US assistant captain Davis Love at the second hole and rode around the course with him on a cart as a lucky charm.
