COLOMBO - Pakistan are eager to celebrate senior batsman Younus Khan's 100th Test appearance with a series-clinching victory against Sri Lanka in the match starting Thursday in Colombo. Misbah-ul Haq's tourists are riding high after a 10-wicket triumph in the opening Test in Galle even though the first four sessions of the match were washed out.

Misbah wants his team to perform equally well in the 37-year-old Khan's landmark Test at the P. Sara Oval and take an unbeatable lead in the three-match series -- a feat which has eluded them on Sri Lankan soil since 2009. "Younus is the backbone and a very special member of the Pakistan team," Misbah told reporters on Wednesday. "Playing 100 Tests is a huge achievement for any cricketer.

"He brings a lot of value to the team and brings a lot of good, positive energy. We all wish he can make his 100th Test memorable with a lot of runs. And we want to honour him by winning the match." Khan will become only the fifth Pakistani to play 100 or more Tests after Javed Miandad (124), Inzamam-ul Haq (119), Wasim Akram (104) and Salim Malik (103). Khan's 8,594 runs put him in third place among Pakistan's leading run-getters in Tests behind Miandad, who scored 8,832 runs, and Inzamam, who had 8,829.

Khan's 29 Test centuries, the same as Australian legend Donald Bradman, are the most by any Pakistan batsman. Inzamam is in second place with 25. Misbah said the tourists were hungry for further success after they fought back from early setbacks to record an emphatic win in Galle. The tourists bowled out Sri Lanka for 300 after electing to field first, but were themselves reduced to 96-5 before Sarfraz Ahmed and Asad Shafiq launched a gritty fightback.

The pair put on 139 for the sixth wicket in quicktime to turn the tables on Sri Lanka, with Shafiq making 131 and Sarfraz 96, as Pakistan gained a 117-run lead. Yasir Shah then ripped through the second innings with figures of 7-76 -- the best by a leg-spinner on Sri Lankan soil -- to bowl out the rivals for 206 before chasing down the 90-run target.

"We gained a lot of confidence from the first Test and just want to carry that momentum in the remaining games," the 41-year-old Misbah said. "Everyone is focused on tomorrow's Test. We can't afford to live in the past. Every new match is a fresh start." Misbah hinted that all-rounder M Hafeez was likely to bowl in the match even though umpires reported his action after the Galle Test for a second time in seven months. Hafeez, who was cleared to bowl in April after being reported for the first time last November, is expected to undergo mandatory testing next week. But regulations allow him to bowl till the test results are declared. If his action is found to be illegal after testing, Hafeez will not be allowed to bowl for a year. "It's very disappointing that he is under the radar again," said Misbah. "It can be so frustrating for the bowler to be reported a second time. But the good thing is that he can still bowl in this match and that's a plus point for us. He has an important role to play."

If there is a home venue Sri Lanka would prefer not to head to after a loss, it would be the P Sara Oval in Colombo. There is typically extra bounce on the surface, and a little help for seamers. On each of the last three occasions Sri Lanka have played here, they have lost. The only difference is that in those series, they had arrived with a 1-0 lead, secured in Galle.

Sri Lanka's Galle tormentor Yasir Shah may not be a menace until later in the match, but the prospect of Wahab Riaz hurling balls at helmets on the most reliable result pitch in South Asia is thrilling for all but the hosts' batsmen. Suranga Lakmal may generate seam and carry here for Sri Lanka too, but the variety of Pakistan's attack gives them an edge. In mitigation, Sri Lanka possess the most successful batsman at P Sara: Kumar Sangakkara has 821 runs here, at an average of 54.73.

For so long Pakistan had outgunned Sri Lanka only in the bowling, but at present, the batting orders seem almost even. Pakistan are famously brittle - maybe less so in the past year - but since Mahela Jayawardene's retirement, Sri Lanka have been soft too. Sarfraz Ahmed's sublime form in the lower-middle order will have Pakistan in good spirits, while Angelo Mathews' descent from the peaks he scaled in 2014 might concern Sri Lanka. In Mathews and Dinesh Chandimal, Sri Lanka have two outstanding players of pace who have hurt Pakistan in combination before. Their challenge will be to rediscover that capacity despite the myriad disappointments of 2015 so far.

Aside from possibly playing an extra seamer in place of Zulfiqar Babar if the pitch calls for a pace-heavy attack, Pakistan are simply seeking more of the same. At times it has seemed inconceivable they could produce two similar performances on the trot. Under their winning-est Test captain however, they are skirting consistency.
