Pathania, who collected 6 for 19 in the first innings to bundle Jharkhand out for 45, picked up 7 for 64 on the second day today to run through the visitors even in their second essay, meaning Services needed just 77 for the win.
Pathania ended with match figures of 13 for 83.
In their second second innings, Services were five for no loss from the three overs they faced, needing another 72 runs for a win.
Jharkhand's hopes of an unlikely turnaround were further dented by loss of wickets at regular intervals, as Pathania reduced them to 41 for 4.
