A five wicket haul from Chris Preston (5-25) and another four wickets from Will Rossiter (4-22) helped bundle out Hathern Old for 150 in Division Five West.
A quickfire 35 from Chris Bulmer broke the back of the run chase while a more sedate 39 from Connor Simon ensured a five wicket win for the visitors as they keep pace at the top of the table.
There was last minute heartache for the 1s in their local derby with Syston Town at Mill Lane.
Half centuries from skipper Dave Torr (72), Liam Kinch (66), Ajay Khunti (52) and Jake Gillett (50) saw the home side to 264 for 5 after winning the toss and batting first.
Ram Ghuman anchored the Syston reply with 88 before being seventh man out with 38 still required. Mo Pardesi followed next ball with ten more being added by Billal Pardesi and Asif Mai before the latter was caught at midwicket to give Khunti (4-85) his fourth victim.
With 15 needed in the last over, the odds appeared to be in Sileby's favour, but Pardesi had other ideas as he smashed the fourth ball of the final over for six over cow corner to spark wild celebrations from his teammates.
A wicket from the first ball of the innings was the high point for the 2s as they crashed to a 105 run reverse at Shepshed.
Jacob Smith picked up 2-52 as the pick of the Sileby attack with the home side making 236 for 6.
Sileby lost their way as they slipped to 31 for four before a stand of 84 between skipper Micky Ruddle (39) and Neil Pullen (35) recovered things somewhat to take Sileby to 115 only for another collapse as they lost six wickets for 15 runs to be bundled out for 131.
Finally, the 4s couldn't back up the win last week at Whetstone as an abject batting, bowling and fielding display saw them suffer a six wicket loss at home to Gumley.
Only three players made it to double figures and they were grateful for 30 extras as a string of poor shots saw them dismissed for 120.
Good opening spells from skipper Dave King (3-15) and George Smith (0-12) gave the home side hope as Gumley were reduced to 16 for 3. However, visiting skipper Jason Campe was afforded four lives as Sileby's fielding fell apart.
Campe finished unbeaten on 62 to lead his side home by 6 wickets.
