Dubai, United Arab Emirates : Pakistan's inexperienced spinners left Australia struggling on 59-4 Saturday at stumps on the fourth day of the first test after Younis Khan smashed a record-breaking century to give his team a formidable lead of 437 runs.
Australia still needs 379 more runs to win after losing four wickets for five runs in its second innings after a remarkable two overs from Zulfiqar Babar and Yasir Shah on a turning wicket.
Chris Rogers hit a nervous 23 with Steven Smith not out on 3. Pakistan captain Misbah-ul-Haq declared at 286-2 when Younis reached 103 to go with his first-innings 106 and become Pakistan's leading centurymaker with 26 hundreds.
Ahmed Shehzad also hit a brilliant 131 and featured in a 168-run second wicket stand with Younis.
Pakistan built a strong lead of 267 runs by lunch as Ahmed Shehzad scored a half century on the fourth day of the first test against Australia on Saturday.
Shehzad was unbeaten on 55 with four boundaries and first innings centurymaker Younis Khan was not out on 26 with Pakistan, which had a 1st innings lead of 151, progressing to a solid 116-1.
Australia's lone success came when Steve O'Keefe had Azhar Ali caught behind for 30 after he added 71 runs for the opening stand with Shehzad.
Resuming overnight on 38-0, both openers gradually built the lead before Ali drove hard at left-arm spinner O'Keefe and the ball stuck in the glove webbing of Brad Haddin behind the stumps.
Australia struggled to get early wickets with Shehzad and Ali showing determined resistance against fast bowlers and spinners.
Shehzad started the day with a crisp boundary through extra cover to Mitchell Johnson's full pitched delivery and didn't hesitate to use his feet against O'Keefe by lofting the spinner over long off for another boundary.
He reached his half century off 128 balls by driving O'Keefe for a single.
Younis looked to have continued from where he left off in the first innings. After a watchful start, he hoisted Lyon over the long-on boundary for a big six in the last over before lunch as Pakistan added 78 runs in the first two hours.
