Cootamundra stunned in-form Tolland with a 1-0 victory at Rawlings Park on Sunday.
In a contest largely devoid of genuine chances, it was Cootamundra’s Aaron Kemp who seized a rare opportunity, capitalising on a well-placed long ball just before half-time.
“We just took our chance when we got it and that was the difference in the end,” Strikers co-coach Adam McPhail said.
“It helped that we won our tackles and were solid in defence.”
Strikers remain four points behind fourth-placed Leeton, who claimed a valuable 4-2 win over South Wagga at MIA Sports Field.
Meanwhile, Junee claimed its first victory of the season, downing Young 4-2 at Burns Park.
Jaguars coach Lincoln Weir led the way, finishing with a hat-trick.
Tumut salvaged a 1-1 draw with Wagga United at Rawlings Park on Saturday night.
United's Adam Holmes struck in the 88th minute, before Tumut's Jarrod Casey equalised within 30 seconds.
