It was a tough day at the office for the world no.1 in Arthur Ashe Stadium on Sunday. Novak was denied calendar Slam bid after losing the US Open final in straight sets. Novak’s bid for a record 21st Grand Slam title came to an end in the US Open final as second seed Daniil Medvedev rose to the challenge to topple the Serbian star 6-4, 6-4, 6-4 and claim the maiden major title.
