It took two days, but Jack Sock is one win away from repeating as 18s singles champion. Sock, the top seed from Lincoln, Neb., was leading Marcos Giron (4), Thousand Oaks, Calif., 7-6(5), 3-2, and serving at 40-30 when rain forced the semifinals match to be suspended. The skies never cleared, and the match resumed at 9 a.m. Sunday, with Sock winning, 7-6(5), 6-3 on his second match point. Sock will play Mitchell Frank, the second seed from Annandale, Va. Frank advanced with a 6-3, 6-0 win over Mac Styslinger (9), Birmingham, Va., in a match that finished on Saturday. “He’s obviously really tough,” Frank said of Styslinger. “The first set I got down 2-0. I was really tight in the beginning. I felt some nerves, obviously. “I played some big matches recently, but this is Kalamazoo and I knew it. He came out strong, so to break back was important.” Today’s final was scheduled to be the best-of-five set match, but was shortened to best-of-three because of Sock’s semifinal.
