Rafa Nadal has moved into the Men's Singles quarter-finals in the French Open tennis tournament. Returning to Roland Garros in Paris after his birthday celebrations, he showed no signs of slowing up, railroading compatriot Roberto Bautista Agut 6-1 6-2 6-2 in the fourth round today.The win has taken Nadal one step closer to a 10th Roland Garros crown.Nadal, who turned 31 yesterday, will next face either Milos Raonic or another Spaniard Pablo Carreno Busta for a place in the semi-finals.Nadal has not lost a set so far this tournament, and is on track to win the title without doing so, something he did in 2008 and 2010. Only Bjorn Borg (1978 and 1980) and Ilie Nastase (1973) have achieved that feat.
