Weiron Tan wasted no time in making his presence felt during his rookie season in North America, finishing second at the pre-season Cooper Tires Pro Mazda Winterfest with two wins in five races for Andretti Autosport. The 20-year-old from Kuala Lumpur has since won four races and claimed six poles in the regular season title-chase, but finds himself 51 points out of the championship lead going into the season finale.
