Sri Lanka are convinced they can take 20 New Zealand wickets in the second test starting in Wellington on Friday and tie the series despite losing the motivation of the World Test Championship (WTC).Sri Lanka's hopes of reaching the WTC final were ended in the series-opener in Christchurch, where they lost by two wickets in a cliffhanger decided on the last ball.As galling as that defeat was, Sri Lanka captain Dimuth Karunaratne said his team were encouraged by how much pressure they put the hosts under at Hagley Oval."We challenged the Kiwis' top batters," the opening batsman told reporters on Thursday."Even the (New Zealand) players also talked to me and said they didn't even expect that kind of bowling pressure from the Sri Lankans."I have been touring New Zealand a few times but this is the first time I saw the Kiwis are struggling against the fast bowlers."Sri Lanka's chance of a rare series win in New Zealand has gone but victory at the Basin Reserve would help them end a losing streak in the country going back to 2006 when they split a series.Motivation may be more of a challenge for the hosts in their final match of a roller-coaster home summer after the emotional highs of winning successive cliffhangers against England in Wellington and the Sri Lankans in Christchurch.Firebrand paceman Neil Wagner has been ruled out with a hamstring strain and his passion will be missed, particularly if another match goes down to the wire.Neither team have decided on their 11 but New Zealand are expected to include Doug Bracewell for his first test in years to join captain Tim Southee and Matt Henry in the pace attack."I think it's a deserved call-up after what he's done in domestic cricket over the last number of years,"
