France's Lucas Pouille came from behind to claim his second title of the year with victory over Feliciano Lopez in the Mercedes Cup final in Stuttgart.
The 23-year-old, seeded fourth, fired a total of 29 aces on his way to his second title of the year following his victory in Budapest in April. He also reached the final in Marseille earlier this year.
The 35-year-old Lopez, who last reached a final in August 2016, was aiming for a sixth career title and third on grass when he broke early in the first set to race to the lead.
He then had a handful of opportunities to break again with the score at 1-1 and 2-2 in the second but Pouille held serve and eventually claimed the set in a tiebreak.
"I think I took a little bit more of the opportunities than him," Pouille said.

"He had some break points and didn't make them, and I had only one or two and I made them. So I think that made the difference."
Lopez took the only break in the first set but Pouille saved four more break points in the second and went on to edge the tiebreak 7-5.
Pouille who saved a match point against Jan-Lennard Struff in the round of 16, squandered his first against Lopez with a double fault but made amends on his third with an ace.
