Final five wickets fall for just 10 runs as Cook turns up heat at Outgang Road
Market Deeping suffered a lower order batting collapse as they tumbled to a 102-run defeat on the opening day of the Lincolnshire Premier League season.
Under the captaincy of new skipper Jamie Morgan, Deeping were dismissed for 129 after being 119-5 in pursuit of visiting Lindum's 231-4 in Saturday's clash at Outgang Road.
Deeping had elected to field after winning the toss and their bowlers enjoyed some early success.
Josh Smith ran Richard Bishop out with the Lindum score on just 13 and then a run later Ali Sharp had Pierce Morley-Barnes trapped leg before.
This brought new Lindum skipper Rob Cook to the crease to join Charlies Tomlinson and they set about rebuilding the visitors' innings.
They put on 60 runs for the third wicket before Tomlinson was caught for 40 by Sam Malton off the bowling of Vamshi Parvathaneni.
Cook though continued to score freely in tandem with Ben Rolfs in a match-winning 117-run partnership for the fourth wicket.
The duo took just 57 balls to reach their half-century stand with their 100-run partnership coming in exactly the same amount of deliveries.
Rolfs rattled up his 50 off just 58 balls before he was eventually caught by Parvathaneni off the bowling of James Hook.
Cook helped Lindum past the 200-run mark and then reached his personal century off 138 balls.
He was unbeaten on 107 - which included 14 fours and a six - as Lindum closed on 231-4 off 50 overs.
Deeping lost Smith early in their reply for four before Kieran Judd (23) and Connor Gillett (30) started to bring the hosts back into the contest.
Their 45-run partnership was ended when Judd was bowled by Tom Lindsay who then struck again soon after to have David Sargeant caught by Bishop for one.
Gillett's departure for Deeping's top score of 30 saw Hook (25) and wicket-keeper Malton (16) take over the mantle.
But, once Hook became the first of man-of-the-match Cook's four victims, the Deeping innings collapsed.
They fell from 119-5 to 129 all out as the last five batsmen produced just 10 runs between them.
Cook claimed 4-15 from an awesome eight-over spell while Jake Benson bagged 2-24 from a 12-over stint to ease Lindum to victory.
Deeping face a tough trip to Grantham - who beat Boston by seven wickets on Saturday - this weekend.
