At stumps, Baroda, who won the toss and elected to field, were nine for no loss in two overs with Connor Williams (3) and Satyajit Parab (6) at the crease.
For the hosts, opener Ravneet Rickey scored 42 (4x6) but none of his partners after the exit of Binwant Singh (15), could give stability to the innings.
Yuvraj Singh (0) was dismissed without contributing even a single run to the total. He was bowled by Shekhar Joshi as Punjab were reduced to 39 for two.
Even Mongia, who had hit a brilliant century in the tour match against South Africa, failed scoring just eight runs.
Thereafter, wickets kept falling at regular intervals as Pankaj Dharmani (11), Ankur Kakkar (2) Chandan Madan (0) returned to the pavilion in quick succession.
Rickey was the seventh wicket to fall with the total reading 106. But the Punjab tail managed to add 69 runs for the last three wickets with Amit Uniyal (14), Gagandeep Singh (22), Vineet Sharma (11) and not out batsman Navdeep Singh (22) scoring valuable runs.
Shekhar Joshi (3/36), IS Pathan (3/49) and Rakesh Patel (2/57) were the main wicket-takers for the visitors.
