SAN ANTONIO, Texas — Junior Charlie Martin made a team-leading six birdies and shot a 68 to lead the Eagles to a 1-under-par 287 team score and into a tie for fifth place in the second round of the NCAA Men’s Golf Championship San Antonio Regional at Briggs Ranch Golf Club Friday. The top-5 teams and the top individual not on those teams advance to the NCAA Men’s Golf Championship Finals at Prairie Dunes Country Club in Hutchinson, Kansas, May 23-28. Georgia Southern, which was one of five teams to shoot under par today, has put itself squarely in a position to earn a bid, and things are boiling down to a 6-team tournament for 18 holes Saturday with two spots to the NCAA Finals on the line.
