Canadian GP: Mark Webber tops shortened, drying final practice

Mark Webber grabbed the fastest time in a crazy final Montreal Formula 1 practice, as barrier damage halved the session and the track dried with moments remaining.
Half the session was lost to barrier repairs, required following a heavy crash at Turn 11 in a Ferrari support race.
With Formula 1 regulations stipulating a minimum two-hour gap between practice and qualifying, and television schedules precluding a delayed start to qualifying, the morning session had to be truncated.
Adding to that frustration were the fluctuating track conditions. Although the wait meant some of the moisture from earlier rain had gone, the circuit was still too treacherous for slicks when practice finally got underway.
Sauber's Esteban Gutierrez emerged quickest of the 14 drivers who went out on wet or intermediate rubber, but many preferred to sit it out until there was a dry line.
That was not the case until the closing moments, which effectively turned the session into a single-lap shootout with all 22 drivers out at once dodging through traffic on slicks.
The top spot changed hands a head-spinning 11 times in three minutes, as quicker times were set with every moment on the ever-improving track.
It was Webber who finally emerged on top for Red Bull, 0.353 seconds faster than Adrian Sutil's Force India.
Friday pacesetter Fernando Alonso was back in fourth in the top Ferrari, between Lewis Hamilton's Mercedes and Sebastian Vettel's Red Bull.
Inevitably the chaos offered an opportunity for an underdog surprise, and Max Chilton provided one as he put his Marussia 14th.
Despite the congestion on the circuit and the slippery surface, the only minor incidents were spins for Pastor Maldonado and Daniel Ricciardo.
