Oxford MCCU will have to bat out an entire day if they are to avoid defeat against Middlesex.
Responding to 430 for four declared, Oxford were rolled over for just 57, with Gurjit Sandhu taking four wickets and three-a-piece for Ravi Patel and James Harris.
Middlesex then added a rapid 188 for four in 32 overs. Adam Rossington smashed 98 from 68 deliveries - including 12 fours and four sixes - before Sam Cato ended his fun, while Joe Denly added a half-century.

Leicestershire made up for the lack of play on day one by piling on the runs in their game at Leeds/Bradford MCCU.
After resumuing on 41 for one on day two of three, the hosts were made to toil in the field.
