It was a game to remember for 18-year-old striker Alfonso Tenconi who, after making his senior debut in the win at Havant & Waterlooville on Saturday, scored his first senior goal for the Rebels in the opening minutes.
The match was just under three minutes old when George Hunt played the ball forward for Tenconi, and the striker beat his marker to the ball before lofting it gently over the advancing Ryan Clarke to open the scoring.
Tenconi almost had a second on 19 minutes as he met a low Ben Harris cross from the left, but Clarke blocked with his legs on the goal line.
Slough continued to press for a second, and Harris appealed for a penalty as he appeared to be shoved to the ground from a Matthew Lench cross, but nothing was given.
It took Bath half an hour to threaten Jonathan North’s goal, but did so twice in the space of a minute – first with Alex Fletcher sending the ball wide as he met a low cross at the near post, and then Joe Raynes blazed over from the edge of the box.
The Rebels took their lead into the break, and very nearly added to it early in the second period.
Tenconi was the man to threaten again on 48 minutes as he controlled the ball well in the penalty area before beating his man and unleashing a fierce strike which rebounded off the inside of the post.
North made his first save of the match from Lloyd James, with the visitors then introducing Omar Holness in place of Dan Ball in an effort to change their fortunes.
But very shortly after, Slough doubled their lead with Raynes playing the ball into his own net as he got into a muddle trying to clear Aaron Kuhl’s cross ahead of the lurking Ben Harris.
Just after the hour mark, Bath missed possibly their best chance to get back into the game as Cody Cooke failed to connect with a header when completely free around the penalty spot.
And just a few minutes later, Slough were handed a golden opportunity to wrap up the three points when a spot kick was awarded for a foul on Harris – but Clarke kept his side in contention as he kept out Kuhl’s effort, the midfielder unable to repeat the trick from Saturday.
One more chance arrived for the visitors with Cooke this time forcing a good save from North with a close-range header.
However, Slough were able to see the game out with relative comfort and move up to 15th place.
