Houston Dynamo
After five seasons with Carabobo, Fuenmayor moved to Major League Soccer side Houston Dynamo on 16 January 2018.[4] Fuenmayor made his Dynamo debut on 31 March 2018 in a 2–0 loss against the New England Revolution. He scored his first goal with the Dynamo on 5 May in a 3–2 win against the LA Galaxy. Fuenmayor scored 3 goals and had 1 assists from 22 league appearances in his first season in Houston, but it was a disappointing league campaign as the Dynamo finished 9th in the Western Conference and missed out on the playoffs.[5][6] Houston did enjoy a successful cup run as Fuenmayor helped lead the Dynamo to their first ever U.S. Open Cup title, playing four times in the competition including starting the final, a 3–0 win over the Philadelphia Union.[2][7]
Fuenmayor made his first appearance of the 2019 season on 2 March, a 1–1 draw with Real Salt Lake in the Dynamo's MLS season opener.[8] On 5 March, he made his first career appearance in a continental competition when he started in a 2–0 loss to Tigres UANL in the CONCACAF Champions League.[9] Fuenmayor struggled to remain in the Dynamo starting lineup in 2019 and spent time on loan with the Dynamo's USL Championship affiliate, Rio Grande Valley FC throughout the season, making six appearances for the Toros.[8] He ended the season with eight MLS appearances and 12 appearances in all competitions for the Dynamo during another poor season for the team, missing out on the playoffs again.[9]
Fuenmayor saw his playing time decrease further in 2020 under new head coach Tab Ramos, making five appearances all season as the Dynamo struggled once again, failing to qualify for the playoffs for the 3rd straight season.[10]
During the 2021 season, Fuenmayor only made three appearances.[11] The Dynamo finished last in the Western Conference for the second consecutive season as Houston failed to qualify for the playoffs for the fourth straight year.[12]
Fuenmayor's contract with Houston expired following the 2021 season.[13]
