FONTANA, Calif. — Martin Truex Jr. saw nothing but clean air and green flags down the stretch in his first victory of the new NASCAR Cup season. Truex didn’t get much of a look at Kevin Harvick, whose bid for four straight wins was ruined by an early crash at Fontana. So even while Truex’s Furniture Row Racing Toyota team celebrated, it was a wee bit disappointed not to get a duel with the early-season king. “I think we would have had something for him today,” team owner Barney Visser said. Truex roared to victory at Fontana on Sunday, beating Kyle Larson by 11 seconds to claim the first win of the season for last year’s series champion. Truex won both stages before rolling to the checkered flag on his 16th career victory and his first since that glorious championship day at Homestead last November.
