Simon Pagenaud earned his first victory for Team Penske by holding off Scott Dixon to win the caution-free Grand Prix of Long Beach.

Pagenaud failed to win a race last season, his first driving for Roger Penske. But he entered Sunday's race as the IndyCar points leader and inching closer to his first Penske victory.

It was a controversial win, though, as Dixon and his Chip Ganassi Racing team believed Pagenaud should have been penalized for crossing a blend line as he returned to the track following a pit stop. The Dixon camp interpreted the rule as a clear violation, but IndyCar only gave Pagenaud a warning.

Dixon and team manager Mike Hull both said IndyCar had claimed there would be no more warnings given out this season.
