Go low or go home was the clear message to the field on the opening day of the D+D Real Czech Challenge Open.
On a day when 78 players broke par at Golf & Spa Kunetická Hora more than an hour east of Prague, Northern Ireland’s Chris Devlin and Gareth Shaw were only tied for 34th despite firing three under 69s.
Niall Kearney’s one under 71 left him tied for 60th while Michael McGeady’s three over 75 was joint 119th.
At the top of the leaderboard, 39 year old Francis McGuirk and 20 year old Adrian Otaegui fired eight under 64s to lead by one from Korea’s Sihwan Kim and Spaniard Carlos Aguilar.
American Brooks Koepka, who is searching for a third Challenge Tour victory this season and automatic promotion to the European Tour, started with a two under par 70 that only good enough for a share of 45th after what was truly a day of extraordinary scoring.
