Argentina's Eduardo Romero sits in the clubhouse with the early lead at the 28th U.S. Senior Open after firing a 6-under par 66 at Whistling Straits in Haven, WI.
Romero's opening round included an eagle on 16. He said conditions were ideal early on before winds picked up a bit late.
Romero has one Champions Tour win to his credit and while there's a long way to go, the Argentine is off to a great start.
