Zaheer Khan grabbed an early wicket to put Pakistan under pressure on the fifth and final day of the second Test against India here on Tuesday.
The left-arm seamer held a return catch to dismiss opener Yasir Hameed before Pakistan reached 37-1 in their second innings at lunch chasing a 345-run target off 81 overs to square the three-Test series.
Kamran Akmal, who scored a century in the first innings, was batting on 14 with Salman Butt (eight) at the interval.
Hameed contributed only 14 before driving a fuller-length delivery to Zaheer, who took a smart catch to his right in his fourth over.
India skipper and leg-spinner Anil Kumble shared the new ball with Zaheer and used his seamers and spinners in short spells in a bid to take another wicket, but Akmal and Butt batted cautiously.
India's hopes depend on off-spinner Harbhajan Singh and Kumble on a last-day pitch. They did the bulk of bowling in the first session, sending down 13 of the 20 overs.
Resuming at 141-2, India batted 6.4 overs before declaring their second innings at 184-4 to set a stiff target for Pakistan.
Former captain Sourav Ganguly, playing on his home ground, completed 6,000 runs in Test cricket during his 46 before being bowled by fast bowler Shoaib Akhtar.
Akhtar also claimed the other wicket to fall in the morning session when he bowled wicket-keeper Mahendra Singh Dhoni for 37. Rahul Dravid remained unbeaten with eight.
India lead the series 1-0 following their six-wicket victory in the opening match.
