Spa-Francorchamps, Belgium (My Sportsbook) - McLaren's Lewis Hamilton crossed the finish line first in Sunday's Belgian Grand Prix, but Ferrari's Felipe Massa was credited with the win after race stewards penalized the Englishman for an infraction during his late-race battle with Massa's teammate Kimi Raikkonen.

The victory was Massa's fifth of the season and the 10th of his F1 career.

Hamilton was originally declared the winner at the 4.352-mile Spa- Francorchamps circuit but was handed a 25-second time penalty shortly after the conclusion of the race. He dropped to third place as a result with Nick Heidfeld moving up to second.

Stewards decided Hamilton gained an advantage by cutting the final chicane during his late-race duel with Raikkonen. Hamilton now holds just a two- point lead over Massa with five races remaining in the season.

Fernando Alonso and Sebastian Vettel rounded out the top-five.

With six laps remaining in the 44-lap event, rain drops began to fall on the track. Raikkonen held 1.9-second lead over Hamilton, but as rain intensified in the following laps, the two struggled to keep their cars on the track.

Hamilton chased down Raikkonen and caught him on Lap 42. Hamilton ran across the "bus stop" chicane as he attempted to pass Raikkonen but surrendered the position.

Hamilton then spun on the grass but recovered as he dived past Raikkonen for the lead. With one last effort to win his fourth-straight race at Spa, Raikkonen quickly reclaimed the top spot as Hamilton ran wide, but Raikkonen lost it for good when he spun off the track and hit the wall. He ended up finishing 18th.

With poor weather conditions prior to the start of the race, sections of the track were wet when they rolled off the grid. Hamilton started on the pole and successfully got around the slippery first bend as several cars slid into the asphalt. Heikki Kovalainen started third but dropped to 13th when he was involved in the incident. But Kovalainen quickly made his way back up to eighth position on the fifth lap.

Raikkonen passed his teammate Massa for second on the first lap and then grabbed the lead from Hamilton on the following lap when Hamilton got loose. The two ran first and second until they pitted on Lap 11 with Massa inheriting the lead. Raikkonen was back in front when Massa came in for his stop. The Finn built a four-second lead over Hamilton after the first round of stops was completed.

Raikkonen held a six-second advantage over Hamilton just before the two pitted at the same time on Lap 25. However, Hamilton was able to narrow the margin to 3.8 seconds after their stops.

Raikkonen did not add any points to his season tally. The defending F1 champion is now 19 points behind Hamilton.

The next F1 race is set for Sunday, September 14th, in Monza, Italy.
