FrogginBullfish Posted July 21, 2019 Share Posted July 21, 2019 To be fair, Xander's the one making a big deal out of it. He's the one who made it public that his driver failed a test. It's understandable why he's upset as some are questioning his integrity, but none of the other three who failed. According to Xander there was a PXG and a TM that failed, none of whom have publicized that their clubs failed. The R&A started testing them at last year's Open so players had to be aware that they might have their clubs tested and they felt 30 drivers were a large enough sample size. Maybe next year they'll test the whole field after Xander and three others failed. Four of thirty drivers suggests that up to 21 drivers in the field would be considered non-conforming this year, which given the R&A's stance on the distance issue, it's definitely not something they'd be happy about.It's pretty crappy people are questioning Xander's integrity as according to MGS' Tony, the fail came down to differences in the way Callaway measured CT and how the R&A does. And according to Tony all the drivers failed by only 1 point. Xander's driver head was two grams too heavy and that's what caused the failure. It's an unfortunate situation for him but his driver wasn't conforming and unfortunately he has to deal with it. It is unfair that there's potentially other drivers out there that are non-conforming though but it's not like the R&A can change anything now. The best they can do is just test everybody next year to avoid a situation like this. So what. The guy is squeaky clean and has a solid reputation.
