Danielle Collins' rich form in what will be her final season continued as she beat Russia's Daria Kasatkina 6-2 6-1 to win the Charleston Open.
Collins, 30, made it back-to-back tournament wins following last week's Miami Open success.
The American, who has announced plans to retire at the end of this season, has now won 13 matches in a row.
"I'm blessed to be able to have the opportunity to live out my dream, I am so grateful," said Collins.
Collins, who will move up to 15th in the world rankings, took 77 minutes to defeat Kasatkina, the 2017 Charleston winner.
