TRENTSIDE slipped back into the relegation zone following a heavy defeat to local rivals Tutbury at the Mill.
The win lifts Tutbury well clear of the drop zone and opening batsman Kamal Manek had a big say in the eventual outcome.
The young Tutbury all-rounder hit an excellent 78 to help his side to a challenging 214-8 and then returned a miserly 2-15 as Trentside slumped to a disappointing 99 all out in reply.
After electing to field, Trentside grabbed a couple of early wickets as Tutbury stuttered to 23-2, but Manek joined forces with Sam Wesson (49) to add an important 96 for the third wicket.
Chris Neagle (2-48) and Ryan Ayling (4-18) hit back for the visitors, Tutbury slipping to 179-7, but as events transpired the hosts already had more than enough runs on the board.
Lewis Brown (13) and Chris Lowe (10) put on 33 for starters after the break, but they were to be the only batsmen to reach double figures as Manek and Matt Edgerton (3-33) confirmed Tutbury's superiority.
Chris Neagle and Karl Hancox (9no) defended stoically for a time but the inevitable came halfway through the 30th over.
Trentside are only two points adrift of safety in the battle for survival and with five games left have plenty of time to stay up.
Games against bottom side South Wingfield and struggling Sandiacre Town 2nds could prove crucial in the scrabble to survive.
The top-of-the-table clash in Flint Bishop Division Two ended in a draw but it was Ambergate who got the better of rivals Alrewas to cut the latter's lead at the top to just 12 points.
Alrewas skipper James Burton won the toss and fielded and Matt Frend (4-69) duly obliged with a trio of wickets to leave the visitors struggling on 48-3.
But David Whiteley (34) survived the opening exchanges and was joined in the middle by Jonathan Heath (66no) and a successful repair job followed.
The pair added a crucial 73 for the fourth wicket and Ambergate were always in charge thereafter.
Rob Heath (37) chimed in with a fine knock and the visitors reached a healthy 205-6 despite late wickets for Ollie Broadway (2-46).
In reply, both James Burton and Tom Chapman struggled, although Alrewas still reached 52-1 thanks to the efforts of young opener Gareth Woolley (35).
Josh Jones (23) also batted well but by this time Phil Mason (2-36), Josh Nicholas (2-38) and Jack McIver (3-30) had already made their mark, and the hosts were in serious danger of losing their 2014 unbeaten record.
A fairly healthy 80-3 became a desperate 114-8 but Billy Hodgkinson (20no) stepped up to deliver his side a draw and what may turn out to be a vital share of the points.
