Ben Shelton of the USA celebrates after winning his quarterfinal match against Frances Tiafoe of the USA on Tuesday. NEW YORK: Big-hitting Ben Shelton blasted his way past Frances Tiafoe 6-2 3-6 7-6(7) 6-2 and into the U.S. Open semi-finals on Tuesday in an all-American match up that lived up to its blockbuster billing. With the victory the 20-year-old Shelton becomes the youngest American to reach the U.S. Open men’s last four since Michael Chang in 1992, setting up a meeting with one of the greats of the game — 23 times Grand Slam winner Novak Djokovic. “Feeling like I left it all out here tonight,” said the 47th ranked Shelton, who is still searching for his first ATP Tour win. “Emotional battle and thanks all you guys for staying so late. “Hell of an atmosphere. Thanks for pushing me over the line.” There are not too many sporting events in New York that create more buzz than an all-American clash under the Arthur Ashe Stadium lights at the business end of the season’s final Grand Slam. The atmosphere during a night session is always electric but it was dialled up a few notches for Tiafoe and Shelton, the contest the first in 15 years two feature two Black American men battling on the world’s largest tennis venue. James Blake and Donald Young met on Ashe in the opening round of the 2008 U.S. Open but the stakes were considerably higher on Tuesday, with the winner moving on to face Djokovic for a place in Sunday’s final and the opportunity to end a 20-year U.S. Open title drought. The 10th seeded Tiafoe, who electrified the home crowd with a run to the semi-finals last year, had dropped only one set en route to the quarter-finals but it did not take long for Shelton to take a second. Shelton came out guns blazing, with his groundstrokes struck with such venom they drew gasps from the capacity crowd. There was no mistaking where the momentum was going into the fourth with Shelton hammering a backhand winner down the line that a flat-footed Tiafoe could only watch to clinch the early break. Another break at 5-2 and Tiafoe’s fate was sealed with Shelton holding serve for the win.
