In only their second game in the Premier League, Alford provided the surprise result of the weekend with a nine-run win over last year’s runners-up Grantham.
Batting first at Train Fen Holt, Alford lost two wickets on 19 - bringing Matt Keeling and Andrew White together in a stand of 55.
White went on to make 57, his dismissal leaving Alford 123-5.
Sam Lempard then took over, hitting 42 and a late unbeaten 20, from Nick Bennett took the final score to 203-9.
Grantham got off to a better start, Ross Carnelley and James Dobson sharing an opening partnership of 61, but by the time Carnelley was caught off White for 56, Grantham were 114-4.
From here, Matthew Wing anchored the pursuit but lost partners to White’s bowling.
Going into the final overs, Grantham were always in sight of victory but the Alford bowlers stuck to their task, White rounding off a man-of-the-match performance by taking the final wicket with the visitors on 196 and three balls of the match to spare.
Wing was left stranded on 53 not out and White ended with 5-51.
At Grimsby Town, Sleaford were bowled out for an unexpectedly low 125, having reached 50-2.

Grimsby’s reply got off to a poor start, two wickets falling for just 12 runs, bringing last weekend’s match-winner Steve Crossley to the crease to add 42 with Geoff Middleton then partner Hayden Tice in a stand of 51.
However, the next three wickets fell for just six runs, including Crossley for 54, before Jack Harrison and Harrison Tice mounted a rearguard action to take their side to 124.
Harrison was out on this score, leaving Tom Thompson to walk out and hit a winning four off his first ball to win the match.
