Turlach Ur's Grade 4 band won each of the four events it entered in 2018, completing a two-year undefeated streak since its 2017 promotion to Grade 4. This was enough to secure the MWPBA's Champion Supreme title for most aggregate points across the season, which the band also won following its 2015 Grade 5 campaign. The MWPBA announced Turlach Ur's promotion to Grade 3 for 2019 at its November 3, 2018 annual meeting.
