Simona Halep is happy with her season, having reached No. 1 and her second Grand Slam final.
The Romanian finished with a 1-2 record at the WTA Finals, but said her third match against Elina Svitolina was an improvement on her lackluster performance against Caroline Wozniacki in her second match.
"I think I played better than Wozniacki's match, and this was my goal, actually," Halep told press at Singapore. "It's been a great year and I'm happy to go to the holiday now."
Though Halep has not gone beyond the round-robin stage in any of her appearances at the WTA Finals, she said, "I'm a different player and I'm stronger. I think I improved a lot in myself and also in my game.
"I will not let this tournament ruin everything I built this year, so I'm OK and looking already forward to the next year to have a good, a better start."
Halep will finish the year at No. 1 after Karolina Pliskova lost her semifinal match to Wozniacki.
