Louth Second XI travelled to Lincolnshire County League leaders Holton-le-Clay on Saturday in a top-of-the-table clash in Division One.
The visitors started the day seven points behind Holton who won the toss and batted first in sunny conditions.
Reggie Koen (3-0-15-1) struck early, but runs were flowing at a rate of five an over. Spin was introduced in the eighth over as Phil Burrell replaced Koen.
Stewart West then replaced Robbie Dwyer (5-0-28-0) and dismissed Portus in his forst over, caught behind by Henry Tye.
Runs dried up as both bowlers settled into a good line and length with only 29 coming off the next 10 overs, Burrell removed Holmes caught and bowled for 39, and West then trapped Marshall leg before for one.
In the next over, Burrell had Rob Griffin lbw for 19 and Gash caught in the deep for two as the leaders slipped to 82-6.
A steady partnership between Rich Griffin and Plaskitt added 35 runs in 14 overs before Burrell (15-3-36-4) trapped Griffin (15-4-36-3) lbw for 12, and West removed Barker without scoring to finish his excellent spell.
Ford and Plaskitt (58 not out) attacked some wayward Louth bowling to finish their 45 overs on 171-8.
After tea, Louth remained very confident, but the top order was blown away by Ford (13-4-45-6).
He had West (13) caught at third man, and Steve Wright caught at mid-off for 17 as the visitors teetered on 41-2.
Things got worse when Koen was trapped in front for 13, and Dean Jacklin (7) was also adjudged lbw to Ford as Louth were in serious trouble at 59-4.
Henry Tye and Zain Siddiqui rebuilt until Tye played down the wrong line and was bowled for 20.
Kully Bains departed in the next over without scoring, soon followed by Siddiqui (1) as Louth looked dead and buried at 73-7.
Robbie Dwyer and Niall Illingworth batted sensibly to move the score along before Illingworth was bowled for five. Burrell joined Dwyer and was soon on his way back lbw for five, and last man Jase Fisher was bowled for one.
Dwyer was left stranded on 15 as Louth were bowled out for 100 in only 26.5 overs.
The batting will need significant improvement next week as the team visit Scunthorpe.
