Replying to Andhra's first innings total of 438, Dahiya showed a fine temperament to occupy the crease for 235 minutes while Varun Kumar produced a more belligerent 75 as Delhi reached 386 for seven before play was called off after the sixth mandatory over due to bad light.
Both the teams failed to garner any points from the match since the first innings could not be completed, thus completing their league engagements with six points each.
Resuming at the overnight score of 155 for one, Dahiya and Pururaj Singh (47) put on 127 runs for the second wicket to keep Delhi on course for the first innings but a few quick wickets after their dismissals allowed the hosts to wrest the initiative.
Dahiya faced 183 balls and struck one six and ten boundaries during his knock of 93 while Pururaj Singh was much more sedate occupying the crease for 360 minutes for his 247-ball 47 that was studded with five boundaries.
Star batsman Ajay Jadeja was dismissed cheaply for 18 and Rajan Gupta (8) also returned to the pavilion quickly to throw the Delhi innings in disarray.
Varun Kumar, however, stemmed the rot with his superb knock that contained nine hits to the fence. N S Negi (40) and Harinder Choudhary (38 not out) were the other notable contributors. Kalyan Krishna was the pick of the Andhra bowlers claiming three wickets for 91 runs.
