Zach Johnson revealed in a press conference on Friday that the US Team were struggling with a sickness bug within the camp.
Yesterday was a brutal day for the Americans in Rome, suffering a 4-0 whitewash in the opening session, before going on to fail to win a match in the fourballs.
But there may be a reason for their slow start, with Johnson revealing that there may have been an illness in camp yesterday.
‘There’s been some unforeseen things that we’ve had to navigate around, which is really unfortunate, in the sense of health,’ The US Team captain said on Friday.
‘It’s not an excuse, because we have depth, but I’ll just say, I’m grateful we have a team doctor.
He added: ‘We’re just fighting things, I mean, internally. It’s kind of passed around a little bit, caddies, players.
‘It is what it is. But it’s nothing more than that. Guys are fighting and playing regardless. I mean, it’s not anything that’s kind of weighed us down because of the depth we have and because of the many options we think we have.’
The Ryder Cup is the pinnacle of golf with the ongoing 44th edition taking place at the Marco Simone Golf and Country Club on the outskirts of Rome, but Team USA slumped on the opening day.
