Collin Morikawa made his second appearance for the USA Team for the 2023 Ryder Cup in Rome, Italy. Morikawa's first experience was an unforgettable one as he dominated along with the USA team as they went on to defeat Team Europe. In 2021, Morikawa scored 3.5 points which is phenomenal for his debut. In 2023, Morikawa had to face much tougher competition making it hard for him to find the score column as he only notched one point. His one point came on the Saturday afternoon Four-Ball match. He was paired up with Sam Burns and they defeated Viktor Hovland and Ludvig Aberg. This 2023 USA Thursday Ryder Cup polo is autographed by Collin Morikawa.
