Gujarat Lions were beaten by Kings XI Punjab, who put up a strong all-round show to end their four-match losing streak with a 26-run victory.
Opening batsman Hashim Amla smashed 65 as the visitors posted a challenging total of 188/7 in 20 overs. In reply, Gujarat could score only 162/7 as the eighth-placed team succumbed to its fifth loss in seven matches.
"You can't chase 190 every time. Bowlers have to do something. We haven't won any 4 p.M. Games. It's a learning curve for us. Spinners have to step up," Raina said after the match.
Raina, who scored 32 runs off 24 balls, also spoke about the pitch.
"We thought we could still chase it down, but while we were batting, the wicket got slower and Sandeep (Sharma) and Mohit (Sharma) bowled good slower balls and made it hard for us to hit," the skipper said.
"At this stage, I can't say anything. We have to go there. Couple of injury issues, but we have to win more games, we can't just talk in training. We'll go to Bengaluru, regroup and hopefully we can win," he added.
