Chasing 215 for victory against Punjab, Hyderabad reached the target with five balls to spare at their home
The former Real Madrid and Liverpool coach is under growing pressure after Dalian lost 3-2 to Shenzhen FC behind closed doors.
Former Napoli skipper Marek Hamsik and ex-Premier League striker Salomon Rondon scored in the second half as Dalian fought back from 2-0 down.
But Cameroonian forward John Mary slotted in a 74th-minute penalty for Shenzhen, who last week sacked AC Milan legend Roberto Donadoni as their coach.
Benitez had to drag an angry Rondon off the pitch at the final whistle after the giant Venezuelan was involved in a clash with the Shenzhen players.
Donadoni will be replaced by Jordi Cruyff, son of Dutch legend Johan, but the former Manchester United and Barcelona midfielder is yet to join up with Shenzhen.
Spaniard Benitez, who took Liverpool to the 2005 Champions League title, has seen his Dalian side draw twice and lose four times since the coronavirus-delayed CSL kicked off last month.
As part of the revamped season to thwart the virus, all matches are being played in either Suzhou or Dalian with the 16 teams split into two groups of eight.
In the Dalian-area group, Dalian Pro are bottom and their next match is against Fabio Cannavaro's reigning champions Guangzhou Evergrande - who are top.
All matches have been played without spectators so far because of the coronavirus but 1,000 fans will be allowed in for the first time this season on Saturday.
