As the second-highest non-qualified European player on the Pro Tour Order of Merit, Meulenkamp played in his first PDC World Championship in 2015. He faced Mark Webster with finishing proving to be the weakness in both players' games as they missed 64 darts at doubles between them. Meulenkamp had a checkout percentage of 19% and was beaten 3–1 in sets. He lost in the final of the Apatin Open to Boris Krčmar.
