Patrick Riordan had an almost flawless round to open the 24th Metropolitan Amateur on Thursday at Westwood Country Club.
Riordan had seven birdies on his card to go with a lone double-bogey on the ninth hole to fire a 5-under 66.
“I was kind of rolling until (No.) nine, doubled nine, turned the corner and settled down,” Riordan said describing his round. “Birdies the two par 5s, kept it rolling and birdied 18 to finish.”
Skip Berkmeyer, the 2009 champion, is two strokes back after opening with a 68.
“68 is a good start, you can always shoot yourself out of a tournament on day one, so it was nice to shoot a good number and off to a good start.”
Three other golfers turned in red numbers on day 1. Brendan Bargetzi, Joe Migdal, of Ballwin, and Bryan Bohme each fired 1-under 70’s to start the championship.
Kyle Weldon, who has won the championship the past two years, is among a group tied in 13th place with a 1-over 72.
Round 2 begins at 7:30 a.m. Friday.
The field will then be cut to the low 40 scores and ties for the final round Saturday.
