Sam Groth has steamrolled seeded Serbian Viktor Troicki to advance to the third round of the ATP’s Washington Open while fellow Australian Lleyton Hewitt made his last appearance at the tournament he won over 10 years ago.
Groth was far too good for world No.20 and ninth seed Troicki in an emphatic 6-3 6-4 victory on Tuesday.
He will next face Spaniard Feliciano Lopez, who was pushed all the way by Hewitt before recording a 4-6 7-5 6-3 win.
It was Hewitt’s final outing at the hardcourt tournament he won in 2004 as he eyes retirement at next year’s Australian Open.
