Zimbabwe were all out for 145 at Queens Sports Club as they sought a second victory over the tourists in three days having won by 80 runs in a rain-shortened tour opener.

Pakistan then atoned for a poor batting show on Sunday with Ayub and fellow opener Abdullah Shafique (32 not out) unstoppable as they reached their target in 18.2 overs.

Ayub struck 17 runs and three sixes off 62 balls in a 75-minute stand while Shafique claimed four fours in the southern city.

Ayub reached his century off 53 balls – the second fastest in an ODI international by a Pakistani after Shahid Afridi.

Zimbabwe, seeking a first ODI series win over Pakistan, utilised five bowlers, but none made an impression with Brandon Mavuta, who conceded 47 runs in four overs, particularly expensive.

After winning the toss, Zimbabwe were quickly in trouble with openers Joylord Gumbie (five) and Tadiwanashe Marumani (four) back in the pavilion with less than four overs bowled.

Only Dion Myers, who struck six fours in his 33, and veteran Sean Williams, who posted 31 before being trapped leg before by Ayub, impressed for the home team.

Pakistan-born all-rounder Sikandar Raza, often the batting saviour for Zimbabwe, made just 17 before becoming one of three victims of Salman Ali Agha.

Abrar Ahmed took four wickets and Ali Agha three for Pakistan, who arrived in southern Africa after a 3-0 ODI series loss in Australia.

The Zimbabwe ODI series decider is set for Thursday, followed by three Twenty20 internationals from Sunday, also in Bulawayo. Pakistan then visit South Africa for an all-format tour.
