Christian Harrison, the younger brother of Ryan, scores his first ATP level and Top 100 win with a 6-1, 6-7 (7), 6-2 victory over Alejandro Falla in Atlanta. The 19-year-old Harrison came into the tournament with a No. 373 ranking and has been mostly playing Futures. He received a wild card into the tournament.

Christian Harrison said that he and Ryan were recently joking about whether he won his first ATP main-draw match before the 21 year-old Ryan won his first tournament.

“The main thing for me is it starts on the practice court and getting a good attitude out there to make sure to work harder than everyone, because it’s tough to jump into a tournament and expect to do well,” Christian Harrison said. “It doesn’t really work that way. Once you put time on the practice court and try to focus hard on getting the most out of each day, then the results will come.”

Christian Harrison will play top-seeded John Isner in the second round. Isner has beaten Ryan Harrison in three out of their four matches in 2013, including a straight-sets win in Newport earlier this month.
