Roger Federer came to the ABN AMRO World Tournament aiming to secure a return to the top of the world rankings. He achieved that goal Friday. On Sunday, he put an exclamation point on a remarkable week by winning the tournament for good measure. Federer overpowered an ailing Grigor Dimitrov 6-2, 6-2 in less than an hour to win his 97th career title. “What a week it’s been. Absolutely amazing,” Federer said. “The goal was to make the semis and I won the tournament so of course I’m incredibly excited and so, so happy.” The 36-year-old Swiss extended his domination over the player once dubbed “Baby Fed” for the similarities in their playing style, registering his seventh victory in as many meetings.
