Hubbard tapped in his last putt, then dropped to a knee to pop the question.
Hubbard, a 25-year-old tour rookie who shot an even-par 72 in the first round Thursday, told the wire service that his mediocre score helped lessen the pressure leading up to the big moment. "If I had a really good round going, I definitely would have been thinking on 18, 'Oh God, don't blow this.' But it was just a frustrating, ho-hum day, so it kind of kept my attention off the last hole," he said.
In the segment above, Hubbard tells ESPN his future mother-in-law came up with the idea of linking the engagement with one of his tournaments. "I couldn't think of a more special place than Pebble Beach," he said.
