“What a week, I’ve really enjoyed myself,” said van Gisbergen.
“I felt pretty rubbish today, leaking out both holes. That wasn’t fun.”
The win lifts van Gisbergen up to 30th in the Cup standings, having only secured one top-10 finish through prior to winning in Mexico.
The Trackhouse Racing driver said it was one of his best ever races.
“I’ve been privileged to have some great ones in my time, but when I go slow I lose concentration so I was just trying to stay in a rhythm and a routine,” said van Gisbergen.
“Josh [Williams] and Stephen [Doran] were doing a great job keeping me calm and focused. Man, that was epic.”
Last season was van Gisbergen’s first full year based in the United States, where he split his time between the Cup series and the second tier Xfinity series, where he won three races.
