(CNN) -- American journeyman Lucas Glover denied Phil Mickelson a fairytale victory at the U.S. Open as he kept his nerve to close out a two-shot victory at Bethpage Black on Monday.
Glover celebrates claiming his first major title by two shots from a trio of chasers.
Mickelson, who was playing while his wife Amy battles breast cancer, had to settle for a share of second place with fellow Americans David Duval and Ricky Barnes.
It was a record fifth runner-up finish at the U.S. Open for Mickelson as Glover, who had not won since 2005, fired a final round three-over-par 73 in tough and windy conditions to finish on four-under 284.
Mickelson, with the majority of the final day crowd rooting for an emotional victory, eagled the par-five 13th to move into a share of the lead at four-under with Glover, but crucially dropped shots at 15th and short 17th.
"I put myself in a great position to close it out but I didn't finish it off," Mickelson said.
"Certainly I'm disappointed but now that it's over I have more important things going on."
