Carla Suarez Navarro took the court at the US Open for the last time on Monday and fought valiantly as she always does. The Spaniard could have easily lost the second set against Danielle Collins by a landslide, having faced eight break points. But she scrapped and clawed her way to a respectable 6-4 second set, much to the delight of the crowd.

“I lost, but this year for me was a gift, you know,” Suarez Navarro said. "Last year on these dates, I don’t know if I can be here one more time or not, and I’m here. I’m happy for that.”

Perhaps the Spaniard will stage another comeback at some point down the road, but for now, Suarez Navarro and her beautiful one-handed backhand have played her last match at the US Open.

All-time ace leader Ivo Karlovic, however, is definitely calling it quits after an unfathomably lengthy 21 year pro career. Karlovic fell to Andrey Rublev in straight sets, 6-3, 7-6 (3), 6-3. One of the funniest and most likable guys on tour, “Dr. Ivo” fittingly struck an ace on the last serve of his career.

An honorable mention goes out Suarez Navarro’s countryman Pedro Martinez, who saved five match points in his come-from-behind victory over James Duckworth, 4-6, 4-6, 7-6 (7), 6-2, 6-2.
