Tickhill secured a comfortable seven wicket win over Collegiate B.
But they lost their unbeaten record on Monday when going down to early leaders Houghton Main.
The Alderson Drive club were indebted to Callum Stuart for their second league win of the season on Saturday.
Stuart ripped his way through the Collegiate top order, taking the first four wickets to fall to leave them reeling at 22-5.
The visitors were eventually all out for 115. Stuart polished off the final two wickets for an excellent return of 6-32.
Tickhill made light work of reaching a winning total, for the loss of three wickets. Michael Jepps saw his team home for the second week in succession with 55 not out.
Tickhill came unstuck at Main, however, where they were bowled out for 74 chasing 147 for victory.
Sprotbrough’s first ever game in the top division ended in a 38-run defeat at Darfield.
Alex Morris compiled an excellent 72 to take Darfield to 107-1 when he became the second wicket to fall.
The home side struggled after that thanks to an excellent spell of bowling from Ashley Langdale who came on at third change and waltzed his way through the Darfield line-up, capturing five of the seven wickets that fell and ending with an analysis of 5-46.
In reply Sprotbrough found it difficult and only Charlie Kaye, who scored 43 out of their total of 120 all out, made any telling contribution.
Darfield’s strike duo Sayed Hassan (4-39) and Tabassum Bhatti (3-25) caused the most problems.
On Monday Sprotbrough also came up short against Conisbrough, who won by 64 runs at Melton Road. Arosh Jonoda claimed 6-26 for the visitors.
Rhys Mann (pictured inset) scored an excellent 104 as Warmsworth eased to a 120-run win over Norton Oakes in Division One.
Mann’s innings included eight fours and two sixes, while Andrew Haywood (45) and Ryan Pearson (46no) helped the Common Lane club post 222-3.
Jack Rogers then claimed 3-28 and Josh Matthews 4-34 as Norton Oakes were dismissed for 102.
In Division Three Doncaster Town B slipped to a disappointing defeat at home to Silkstone United.
Doncaster batted first and struggled to 138-9 from their 46 overs. Kevin Taylor took 3-31 for the visitors.
Silkstone achieved their success for the loss of five wickets. Skipper Robert Wade opened with 44 and Jacob Taylor supported with 39.
George Cowan bowled well for a reward of 4-26.
