Warner: It's been challenging for our batters at home

The Delhi Capitals batting unit has struggled "to work out what the best total is" at their home venue this season because of "slow" and "inconsistent" pitches at the Arun Jaitley Stadium, according to their captain David Warner.

Warner was speaking after DC's penultimate league game against Punjab Kings in Dharamsala, where his side scored their first 200-plus total of the season and won by 15 runs.

"I think playing on a nice wicket helps … it's been challenging for us back at home with a lot of slow wickets and inconsistent pitches, it's good to get the guys here for some momentum … at your home venue you want a bit of consistency and that's been the difficult thing. We haven't been able to work out what the best total is there."

It was an opinion shared by Rilee Rossouw, who scored his maiden IPL half-century against the Kings in Dharamsala.

"It's long overdue, let's put it that way," Rossouw said on finally reaching the milestone in his 13th IPL match across three seasons, the first of which was in 2014. "The wicket was really good to bat on, we haven't had many of those this season and it was just good to be on a batting wicket."

DC have won only two out of six home games so far this season, and their scores at the Arun Jaitley Stadium have read: 162 for 8, 172, 128 for 6, 188 for 6, 187 for 3 and 136 for 8.

However, their away record has been poor as well, with three wins out of seven games and scores of 143 for 9 in Lucknow, 142 for 9 in Guwahati, 151 for 9 in Bengaluru, 144 for 9 in Hyderabad, 130 for 8 in Ahmedabad, 140 for 8 in Chennai, and 213 for 2 in Dharamsala.

DC were the first team to get knocked out of contention for the playoffs after losing their first five games of the season. They did manage to win four of their next five, but two more losses ended their hopes of finishing in the top four.

Their final league game is against the Chennai Super Kings in Delhi on May 20.
