MILLSBORO — Clearly, it was going to be a hot day on the golf course for Monday’s first round of the Delaware Open.

But some golfers were a little hotter than others.

Brandon Berry fired a six-under-par 66 and nine players finished under par as the 55th annual DSGA Delaware Open got underway at The Peninsula.

With the 54-hole tournament concluding today with two rounds, there’s lots of contenders still left in a field that started out with 138 players, including 10 past champions.

After Berry, Michael Chanaud, Ryan Rucinski and Blake Hinckley are all two shots back with four-under par 68s.

A total of 33 players made the cut at three-over par 75 or lower. The final group tees off its first round at 10:44 a.m. today.

The 21-year-old Berry, from McLean, Va., plays at Loyola, Md. University.

He had some ups and downs on Monday, carding three bogeys — including a double-bogey six on the par-four eighth hole. But Berry countered those miscues with 10 birdies on the remaining 15 holes.

Those 10 birdies were four more than anybody else in the field.

The three players tied for second — who are all professionals — all finished with six birdies.

The 26-year-old Chanaud, who played collegiately at Towson, also had to overcome a double bogey before playing the back nine at three-under par.

As for former Wilmington University player Rucinski, the 23-year-old had an eventful seven-hole stretch in which three straight birdies were followed by back-to-back bogeys and then another pair of birdies. He then settled down by carding eight pars on the back nine.

Hinckley, a 23-year-old from Wilmington Country Club, put up three birdies and a bogey on both the front and back nines.

Walter Egloff, who won the Open in 2017, is tied for fifth place after shooting an opening-round 69. Mike Tobiason, Jr. is also at 69 after playing the final four holes at four-under par.

Caesar Rodney High grad Jay Whitby, the 2013 champion, is tied for eighth with a 71.

With seven players finishing with even-par 72s, 17 players are within six shots of the lead.

The professional purse for the event is estimated at $13,000. The players in the starting field represented 29 different clubs.
