Hollioake, who produced a superb spell of 3 for 1 in 12 balls, helped dismiss Yorkshire for 217 - two runs adrift of the 219 needed to win. Yorkshire began the day on 74 for 1 - just 145 short of victory.
Superb individual performances from Tom Moody of Worcestershire and Derbyshire's Devon Malcolm were not quite enough to generate a result at Kidderminster.
Worcestershire, chasing 517 from their overnight position of 27 for 1, eventually batted through to close on 467 for 9.
However, a magnificent 168 from Moody, the captain, almost guided them to the highest winning total in a fourth innings in the Championship, while Malcolm took 5 for 65.
John Childs, the slow left-armer, steered Essex to their fifth Championship victory of the season against Glamorgan at Swansea.
Childs took 5 for 60 as the home side, chasing 328 to win, slumped from 78 for 2 at lunch to 180 all out shortly after tea.Reuse content
