Two years on from her only previous venture this far at a WTA event, World No.125 Boserup displayed great composure to close out a 7-6(0), 6-4 victory, setting up a semifinal showdown against Océane Dodin.
Boserup, who is enrolled in an online degree at Penn State, does not graduate until December, and recent success is providing a welcome distraction from looming deadlines. In July, then ranked outside the Top 200, Boserup came through qualifying to reach the third round at Wimbledon.
Her latest run could well take her into the Top 100. And against Bellis she showed enough to suggest that this may not be her ceiling. After a shaky start, Boserup pinched the first set, then played the more assured tennis at the conclusion to the second, fending off a break point before striking decisively in the following game.

Earlier on, Dodin, appearing in her maiden WTA quarterfinal, made another breakthrough by defeating Alison Van Uytvanck, 6-2, 6-4. While Dodin is entering uncharted waters this week, it should come as no real surprise given her recent form on the ITF Circuit, where she has won 13 of her last 15 matches.
In the top half of the draw, qualifier Lauren Davis withstood a late fightback to defeat Alla Kudryavtseva, 6-3, 7-6(4). Davis had won all three of the pair's previous meetings and was made to work hard for number four, closing out the contest after spurning three match points and a comfortable second set lead. In the last four Davis will face either Tereza Martincova or Jessica Pegula.
