Five of the eight semifinalists at The Country Club are ineligible for the USA side. Only one has a title of significance this summer (USGA Junior, won by Scottie Scheffler, who goes up against the strongest player left, Brady Watt of Australia.) Ball plays for VCU and Matthews, for Temple.
Last year, despite Steven Fox's prior anonymity, he still made the USA side for the World Amateur team championships. Could the USGA leave off Ball or Matthews from the Walker Cup side, despite a win at the Am? I can't see them leaving off Scheffler, if he could somehow become the first to win Junior Am and Am in the same year.
