Kent were denied an almost certain victory as their match Twenty20 match with Middlesex was abandoned after just 20 overs were possible.
Middlesex had been restricted to just 146 for seven at Uxbridge after some superb bowling from the Kent attack - with Simon Cook the pick of the bowlers with figures of three wickets for 28 runs.
Former Kent captain Ed Smith was in fine form for the Crusaders, scoring a brilliant 66 from just 50 balls as he shared an opening stand of 48 with Eoin Morgan.
Morgan was the first wicket to fall off the bowling of Morne Morkel, having scored 21 from 19 balls.
The young left-hander drove loosely at the Kent paceman and edged to Martin Van Jaarsveld - who parried the catch to James Tredwell at first slip.
Next to go was Nick Compton, who was caught on the midwicket boundary by Joe Denly after scoring just 11 - giving Cook his first wicket.
The introduction of Cook and Tredwell stemmed the flow of early runs and Cook then picked up his second wicket, that of Jamie Dalrymple for three.
The all-rounder square-drove straight to Ryan McLaren who took a brilliant diving catch at deep point.
Meanwhile, Smith continued to dominate and went to his half-century from just 35 balls with a glorious cover drive which raced to the boundary.
Tyron Henderson, playing against his former county, smashed a huge six off Cook in the 16th over.
He then tried to repeat the same shot with the next ball and drove straight to Morkel at mid-off having scored 12.
Smith was eventually bowled in the 17th over - in trying to make room to drive through the off-side he saw his stumps shattered off an inside edge with the score on 115 for five.
The Crusaders looked to force the pace and lost two wickets in quick succession.
Firstly, Ed Joyce was run out backing up as Chad Keegan drove straight back to the bowler - Yasir Arafat - who knocked the balls off.
Then, Ben Scott was stumped by Geraint Jones for just four with two balls left of the innings - leaving Keegan unbeaten at the end with 23 from 15 balls.
But the weather intervened, meaning both teams are on identical scores with four points from four games in the competition.
