"I was kind of hoping he wouldn't come" - Katie Boulter jokes about boyfriend Alex de Minaur's overnight trip to support her in San Diego final

It was a big week for tennis power couple Katie Boulter and Alex de Minaur as they lifted 500-level titles in San Diego and Acapulco respectively.

Besides the brilliant tennis, De Minaur making an overnight trip to San Diego hours after his own final to support Boulter has seen him win a fair few new fans.

Boulter, reflecting on the week in a video for the Lawn Tennis Association, said she played her best tennis in the final. She also joked that she was hoping that De Minaur not show up only to quickly retract by saying that she was obviously happy to have him there.

"Somehow I ended up in the final playing some of the best tennis I've played in a very long time and I don't know how but I managed to get over the line and it was a little bit of a fairy tale for me," Katie Boulter said.

"I was kind of hoping he wouldn't come but he insisted on it," she joked, before adding, "Obviously, I was very happy that he was there."

Boulter said she and boyfriend winning big titles in the same week was special, especially given that she is always looking to one-up De Minaur.

"Yes, I won my first WTA 500 and [Alex de Minaur] backed it up and won another 500," Katie Boulter said. "So we had a good week."

"It was actually quite a nice way that it worked that he was always one-upping me and I wanted to match him so it kind of felt like a nice little role going on to the rest of the week, but it just made me want slightly even more because he won," she added.
