Delhi's desperate bid to garner full points from the match to revive their hopes of qualifying for the semi-finals from the group received a major setback as the bowlers failed to restrict their little-known opponents even on the second day of the four-day comepetition at the Gurbaksh stadium.
With only two days remaining and Kerala still left with five more wickets, a draw is the most likely outcome and Delhi could at best take two points that too if they manage to take a first innings lead.
But dismissing their opponents early on Friday looks a tough ask for the hosts since almost all the batsmen managed to defy the bowlers and stay long enough at the crease to frustrate the home team.
At close Ajay Kudua was batting on 90 and Sunil Oasis on 28.
Earlier, resuming at 85 for two, the visitors added 201 runs in 69 overs on the second day, which saw 40 minutes of play being lost due to bad light.
Vipin Lal (35) and Hemant Kumar (46) took the score to 120 before the third wicket fell when Hemant departed, offering a catch to Amit Bhandari off Rahul Sanghvi.
Vipin Lal was bowled by off-spinner Sarandeep Singh when the score was 152.
Sreekumar Nair (34) added 75 runs for the fifth wicket with Kudua before being trapped leg-before by Bhandari.
