Despite the quadruple party, he made some minor mistakes in the freestyle where a Salchow jump had to be changed and a triple-shoulder was missed.
- I made some mistakes, which I should not have made.
But that's what it is and I'm moving on from this, says the double world champion Chen who has only won since fifth place in the 2018 Pyeongchang Olympics, according to AP.
Chen had gained a big lead after the short program on Friday and won on the total score of 299.15 compared to runner-up Vincent Zhou's 275.10.
Bell won the women's class despite a fall
Chen has taken a break from university studies at Yale to concentrate on the Beijing Olympics in 2022. His fourth title in Skate America is a close record with Michelle Kwan, Todd Eldredge and ice dancers Meryl Davis and Charlie White.
Maria Bell won the women's class despite falling in a triple-lutz, which only gave the fourth best point in the freestyle.
Bell's fine card program laid the foundation for the victory on the score 212.73.
- I will leave the competition a little disappointed but at the same time I feel proud, Bell says.
