Cambridge UCCE had a good start to their 2005 first-class season, setting Essex a target of 270 to win, after declaring in their second innings on 255 for 4.
Warwickshire batted first, losing three wickets for no runs to collapse to 48 for 4, but Jonathan Trott's three-hour 150 not out lifted the visitors to 296 for 6 declared.
In 45 overs of possible play on the first day, Middlesex amassed 182 for 2, with Ben Hutton making an unbeaten century.
They lost Hutton for 111 on the second morning, but pushed onward to 273 for 3 before declaration, and then dismissed Cambridge UCCE for a sorry 151 before reaching 101 for 3 by close on the second day.
The remaining runs were then knocked off by Park, who finished on 48, and Philip Edwards, leaving the students narrow victors.
After losing two early wickets, Indian Salil Oberoi and Birmingham lad Dan Fox entered the frame.
With 247, he'd made the highest score ever in a Varsity game - and Fox's and Oberoi's partnership of 408 for the third wicket was an Oxford all-wicket record.
By the time captain and all-rounder Paul McMahon (a former Nottinghamshire player) declared, Oxford were 610 for 5, having two and a half days to bowl out their rivals.
