TORONTO, Canada - Australia's youngsters endured a mixed day at the Toronto Masters, with Nick Kyrgios setting up a second-round clash with Andy Murray but Bernard Tomic bowed out in his opening match.
Kyrgios beat Colombia's Santiago Giraldo 7-6 (7-3) 7-5 on Tuesday in his first match since reaching the Wimbledon quarter-finals with a win over Rafael Nadal.
The 19-year-old, making his Masters 1000 career debut, backed up his growing big-match reputation with the 94-minute win over Giraldo.
The world No.72 has risen more than 100 ranking places in the past month-and-a-half and is the only teenager inside the top 100.
He equalled his season record at the ATP level to 6-6 with the victory.
Kyrgios played fearless tennis as he trailed the more experienced Giraldo 5-2 in the opening set, with the wild card winning the opener in a tiebreak.
He claimed victory on his third match point in the second set after breaking the South American in the final game.
