Roger Federer's third-round match on Monday was much more his style. The Swiss was thoroughly tested during his Miami Open presented by Itau opener on Saturday, needing three sets to beat Delray Beach champion Radu Albot of Moldova.
But Federer, after an even start against Serbian Filip Krajinovic, raced past the Serbian 7-5, 6-3 to reach the fourth round in South Florida. Federer, second all-time in Miami wins, improved to 52-14 at the season's second Masters 1000 event.
The 27-year-old Krajinovic stayed with the three-time Miami titlist (2005-06, 2017) in the opener, matching Federer from the baseline. The Serbian made the fourth round at the BNP Paribas Open in Indian Wells (l. to Nadal) and was looking to match that result in Miami.
But the 37-year-old Federer came through in the 12th game to take the opener, blasting a crosscourt forehand winner. He settled in from there, racing to a 4-1 lead behind an early break in the second and finishing with 35 winners to 23 unforced errors.
Federer will next meet Russian Daniil Medvedev or Reilly Opelka of the U.S. The Swiss leads his FedEx ATP Head2Head series with Medvedev 2-0. Federer and Opelka have never played.
