AUSTIN, Texas (AP) Formula One championship leader Lewis Hamilton posted the fastest time in Friday's two practice sessions at the U.S. Grand Prix, but abandoned the second session with about 10 minutes to go to deal with a fluid leak on the cockpit floor.
Afterward, Hamilton seemed confident the problem would be resolved before Saturday qualifying.
"We stopped and pulled the floor up and there was some kind of fluid ... either a fuel leak or an oil leak," Hamilton said. "I'm not thinking about it. We just lost a little time in the session."
