				 The 22-year-old Sock, playing in his first ATP final, saved 
				three set points in the first set tie-break which came after a 
				two hour rain delay when Querry was up 5-4. 
				 
				There was still little to choose in the second set between Sock 
				ranked 46th in the world and Querrey, four places above him in 
				the rankings. 
				 
				Querrey broke to go 4-3 up but Sock broke right back and came 
				out comfortably on top in the second tie-break to secure the win 
				in one hour and 45 minutes. 
				 
				It was the first time since 2003, when Andre Agassi defeated 
				Andy Roddick, that two Americans faced each other in the Houston 
				final.
