The top-two ranked Americans on the ATP Tour will square off for a place in the Toronto final come Wednesday evening at the National Bank Open.
Ben Shelton booked a showdown with Taylor Fritz in reaching his maiden ATP Masters 1000 semifinal. The left-hander halted Washington, D.C. champion Alex de Minaur, 6-3, 6-4, to close out Tuesday's action for his first Top 10 win of the season.
The runner-up here two years ago, De Minaur came in on a seven-match win streak and leading all ATP players with 24 hard-court victories this year. In a game where he had chances to keep pace, the Australian was the first to crack at 2-3 after catching consecutive shots late—a forehand volley and backhand up the line. Shelton was the more effective hitter with 13 winners (to 14 unforced errors) in seizing control of the scoreboard.
