EMOTIONS ran high on Court 6 at Roland Garros where Steve Johnson won an epic four-setter against Borna Coric. Johnson, the No 25 seed from the USA, lost his father and coach Steve Snr earlier this month and collapsed to the court in tears after winning a tiebreak from 4-6 down. Meanwhile young Croatian Coric took his frustration out on his racket, smashing it viciously and repeatedly into the clay before tossing it to the side of the court. Keep up to date with ALL the latest TENNIS news, gossip and rumours Coric was not done and as he left the arena threw his water bottle to the ground as the crowd booed. There had also been drama and controversy in the 10th game of the set. At match point on the Coric serve, Johnson failed to make a volley and then sent the ball flying high into the air. The umpire ruled it was a deliberate action and ball abuse. Johnson had already received a code violation warning and so suffered a point penalty. The American was so incensed that referee Wayne McEwen was called to the court to deal with the row. Coric went on to win the game and then to force the tiebreak, but Johnson took the match 6-2 7-6 3-6 7-6.
