| Tsitsipas, a 20-year-old from Greece, won 78 
				percent of his service points against Tiafoe, a 20-year-old 
				American, and saved two break points en route to a 70-minute 
				victory.
 Australia's Alex de Minaur became the second player assured of a 
				place in the semis by beating 2017 finalist Andrey Rublev 4-1, 
				3-4 (5), 4-1, 4-2. De Minaur lost just three service points in 
				the first set and was broken just once in the match. He also 
				broke the Russian four times.
 
 The United States' Taylor Fritz defeated home-crowd favorite 
				Liam Caruana 1-4, 4-1, 4-3 (9), 4-2 to earn his first victory in 
				Milan. Both players lost their openers on Tuesday.
 
 Poland's Hubert Hurkacz beat Spaniard Jaume Munar in their first 
				ATP meeting. The sixth seed battled five sets before beating 
				Munar, 4-2, 4-2, 2-4, 3-4 (5), 4-1 to move to 1-1 in Group A 
				play.
 
 Hurkacz will face Tsitsipas on Thursday in the last day of 
				round-robin action. The two have never faced off in a 
				professional match. No. 2 seed de Minaur looks to complete 
				round-robin play undefeated when he plays fourth seed Fritz. 
				Rublev aims to earn his second win in Milan when he clashes 
				against Caruana. Munar will look for his first win when he takes 
				on Tiafoe.
 
 The innovative format for players 21 and under, now in its 
				second year, features shorter sets in which the first player to 
				four games is the winner, with a tiebreaker at 3-3.
