The Claines Lane club kicked off life in the West Midlands (Regional) League Premier Division with a 4-3 win at Dudley Town.
Danny Mayne fired Dudley in front with a low shot from outside the box but Raiders responded through Dan Flowers and led after half an hour thanks to Kirk Layton.
Krol then snaffled his brace in the build up to the break but Alex Brogan made things interesting with a bolt from the blue.
The hosts bagged another but Raiders stood firm to kick off the campaign in style.
Victorious boss Karl Gormley said: "It was a brilliant team performance, we really had to dig in second half and I am so chuffed for the lads to win our first game in the Premier Division."
