Earlier, Tevin Imlach and Tagenarine Chanderpaul converted their respective overnight scores of 88 and 78 to much-deserved centuries.
Imlach made 107 (9x4s) from 243 balls, while Chanderpaul got a welcome return to form for an unbeaten 101 (9x4s; 2x6s) from 248 balls as Harpy Eagles declared on 242 in the second innings.
The Championship takes a break and resumes April 10, when the Harpy Eagles will travel to Sabina Park to face the Jamaica Scorpions.
