Leaderboard
England's Justin Rose finished in a tie for 65th on two over par in his first tournament with his new McLaren clubs.
Cameron Young won the Cadillac Championship in Miami on 19 under, six shots clear of fellow American Scottie Scheffler.
Rose was using clubs manufactured by Formula 1 team McLaren, having signed to become their first professional on the PGA Tour.
Six over after three rounds, he shot a four-under 68 at Doral's Blue Monster Course on Sunday.
Rose has been without a deal with a club manufacturer since leaving Honma in 2020.
Young's win - his third on the PGA Tour - was wrapped up in front of watching US President Donald Trump.
World number one Scheffler has finished runner-up in three successive tournaments, including the Masters.
Compatriot Ben Griffin was a stoke further back in third, while England's Alex Fitzpatrick finished in a share of ninth on nine under.
