Jo Bland scored a brilliant second-half winner as Long Sutton replaced Spalding at the top of the table.
Great hockey was served up by both sides at Glen Park on Saturday and the game was played at an incredible pace – testimony to the sport in south Lincolnshire.
Early home pressure was thwarted by Leah Goodley and Bland while goalkeeper Lorraine Wallis was tested, making a great block and clearance with her right boot.
On 20 minutes, a break-away from Spalding’s short corner saw Sutton take the lead.
The ball fell to Jess Hudson midway inside the Sutton half and she carried the ball for a few metres before sending a crisp pass to Lyn Tancred.
She quickly placed the ball to Leanne Woodhead who drifted across the D, drew the keeper and fired home from an angle.
Goodley, Tancred and Woodhead all went close before Spalding levelled on 26 minutes.
After four short corners Spalding finally caught a break with the ball dropping to Georgina Maplethorpe 12 yards out to flick home.
Sutton should have taken the lead again as Woodhead’s shot rattled the post but the rebound fell unkindly for Bland.
Spalding had chances before half-time but Rachael Gadsden cleared up a golden opportunity and the home team went down to nine players as the game got feisty.
Early in the second half Spalding tested the back line of Gadsden, Tania White and Lisa Baker.
Goodley shot narrowly wide but Wallis pulled off a couple of saves to keep the scores level.
Tancred was also denied but Sutton’s fine spell was rewarded by winning a short corner.
Baker injected to Goodley who switched the ball right to Bland. She took the ball forward before neatly lifting her shot over the advancing keeper.
Five minutes later Bland went close again, this time weaving through the defence, but her strike was beaten away well by the keeper.
A short corner needed White to steer the ball away from the Sutton goal line and in the final minutes they held on under pressure for a great away victory.
