Worcestershire, with eight wickets standing, need a further 103 runs to avoid an innings defeat against Loughborough UCCE
Worcestershire's plan to use their first meeting with Loughborough's students as much-needed batting practice backfired.
Having been nought for three, they were made to follow on as they were dismissed for 133. They have a lot of work to do today at Kidderminster if they are to avoid an innings defeat to a university side.
Young pace bowlers Ryan Cummins and Steve Clark did the damage for Loughborough.
The students added 71 runs to their overnight position of 233 for four during a rain-interrupted morning session and declared at lunchtime. No one could have expected what was to follow from a Worcestershire top order packed with first-team regulars.
With the second delivery of the innings, Cummins bowled Worcestershire's acting captain Stephen Peters. One ball later Cummins had former skipper Ben Smith caught at slip.
In the first over from the other end Clark found Stephen Moore's edge. Three batsmen had been dismissed for a duck.
Overseas signing Zander De Bruyn, the South African, got his head down. Although he soon lost debutants Stephen Davies and Daryl Mitchell as Worcestershire slumped to 32 for five, De Bruyn found an able partner in wicketkeeper Jamie Pipe.
They took the score to 98 for six before Pipe departed on 23, he being the only Worcestershire batsman other than De Bruyn to reach double figures.
De Bruyn ran out of partners and his attempt to force the pace was curtailed when he holed out on 81 to become Cummins' third victim.
Yorkshireman Clark ended with the outstanding figures of five for 29.
The students were not finished there, taking two more wickets by the close.
Peters again went cheaply, caught behind off Cummins, for eight.
Dave Wainwright struck the final blow of the day when he bowled Moore for 27.
The only consolation for the home side was that Smith had settled into some form and ended the day having scored 29 not out.
But, badly needing a tonic before tomorrow's County Championship Division Two match against Derbyshire at New Road, Worcestershire will be up against it when they resume this morning.
