The fourth-seeded del Potro broke serve once in each set for a 6-4, 6-4 win on Sunday, capturing his first title of 2012 and the 10th of his career. It was also the first indoor crown for the 2009 U.S. Open champ.
Del Potro improved to 10-5 lifetime in title matches and 1-1 this year. He was a 6-1, 6-4 loser to Roger Federer last Sunday in the Rotterdam final after also losing to the Swiss superstar in the quarterfinals of the Australian Open.
Llodra, the 2010 Marseille champ and 2009 runner-up, fell to 5-5 in finals. He hasn't won a title since claiming the Eastbourne crown two years ago.
Sunday's final was a rematch from the first round of last week's event in the Netherlands. Del Potro posted a 6-4, 6-7 (3-7), 6-4 win in that one, but had a bit of an easier time this week.
The first break of serve came in the ninth game of the first set and it gave del Potro a 5-4 lead. He finished the set with an easy hold, then broke serve again for a 3-2 lead in the second set.
Del Potro did not face a single break point against his own serve during the 83-minute match and won 36-of-40 first-serve points. He improved to 3-0 lifetime against Llodra.
