Bourdais is 3-for-3 this season

On the track in Monterrey, Mexico, temperatures climbed to 125 degrees.
MONTERREY, Mexico (AP) -- Sebastien Bourdais is still the only driver to win this Champ Car season.
Bourdais is 3-for-3 after overcoming a slow early pit stop Sunday to edge Justin Wilson by 3.065 seconds in Mexico's Grand Prix of Monterrey.
Bourdais and Wilson went at each other all afternoon during a virtually crash-free race despite slippery conditions on the asphalt. The 2.104-mile Parque Fundidora road course curves around a rusty, long-closed steel mill in Mexico's third-largest city.
"I think we really gave each other a run for our money," Bourdais said. "Nobody could lay back or anything. It was running flat out the whole time."
The heat was a factor during Sunday's 76 laps, with temperatures at 97 degrees at the start. On the track, they climbed to 125 degrees. Wilson headed to the medical tent after the checkered flag, suffering from mild dehydration.
The others
A.J. Allmendinger, Wilson's RuSport teammate, was third, 14.132 seconds off the lead. He was followed by Paul Tracy, 47.222 seconds behind Bourdais, and Alex Tagliani, whose time of 1:40:.48.030 was nearly 58 seconds slower than the winner.
Bourdais who won Champ Car races last week in Houston and at Long Beach on April 9, started first after posting the top time at Saturday's qualifying session, becoming the first driver since Randy Mears between 1988 and 1991 to win four straight poles at the same event.
He has never started anywhere but up front since first coming to Monterrey in 2003. He last won on this course in 2004.
Bourdais held his lead for the first 23 laps Sunday. But Wilson's crew was quicker when both cars pitted during a caution because of debris on the course, and Wilson moved into first place by three lengths.
"I really thought we had things under control. But then we got out of our box and I saw we were second and from there on I knew it was going to be a tough race," Bourdais said.
Allmendinger then pulled off a risky pass to briefly move Bourdais into third.
"I got around Sebastien on the restart, but more than anything I kind of knew I was probably using more fuel than he was and that he could go longer than me," Allmendinger said. "I was just thinking the first two races he had too many easy victories, so I wanted to make him sweat just a bit this time."
Bride watches
Bourdais, his new bride watching from the pits, and Wilson started on option tires, which feature a softer compound and better grip. Bourdais switched to regular wheels during his first trip to the pits while Wilson went with another set of options, known as "reds."
Wilson led for 28 laps, but Bourdais' early move to regular tires eventually paid dividends. He reclaimed second place, then ran his gas tank down to fumes waiting for Wilson's second pit, which came in lap 55.
