Shahid Afridi claimed 5-16 as Pakistan overwhelmed Kenya by 205 runs to get their World Cup campaign off to a positive start.
Kamran Akmal, Younus Khan, Misbah-ul-Haq and Umar Akmal all contributed half-centuries in a final Pakistan total of 317-7 - helped by a world-record 37 wides among 46 extras.
Kenya's batsmen, who had been bowled out for 69 in a 10-wicket defeat to New Zealand on Sunday, again failed to cover themselves in glory.
Collins Obuya hit three sixes in his 47 but, from the relative heights of 73-2, the Africans collapsed to 112 all out in 33.1 overs.
Pakistan captain Afridi was the star of the show with the ball, winning three lbw appeals among the third five-wicket haul of his 313-match ODI career.
Afridi had won the toss and opted to bat first in the Group A clash in Hambantota, a decision that initially looked questionable as Pakistan openers Mohammad Hafeez (9) and Ahmed Shehzad (1) made slow progress.
Indeed, they were back in the pavilion inside seven overs as Kenya's new-ball pair Elijah Otieno and Thomas Odoyo each made a breakthrough.
But the situation was rescued by a 98-run, third-wicket stand between Kamran Akmal (55) and Younus (50).
Both fell shortly after reaching half-centuries but the baton was picked up in style by Misbah (65) and, in particular, Umar Akmal.
The fifth-wicket partnership realised 118 from 79 balls with Akmal marking his World Cup debut by dispatching eight fours and a six in his 71 from 52 deliveries.
It was also the first time in World Cup history that four batsmen have passed 50 in the same innings.
Medium pacer Odoyo - who gave up 22 in wides - bagged a couple of late scalps to finish with 3-41 but, with 112 runs having come from the final 10 overs, Kenya's target looked well out of reach.
And, despite opening pair Maurice Ouma (16) and Seren Waters (17) putting on 37, so it eventually proved.
The run out of Waters was soon followed by Ouma edging behind off Umar Gul in the 13th over.
Obuya and Steve Tikolo (13) took their side past the low watermark achieved against New Zealand but Tikolo's exit was the start of spectacular meltdown that saw the final eight wickets tumble for 39 runs in 10.5 overs.
Afridi was destroyer in chief, Kenya's middle and lower order being flummoxed by his array of back-of-the-hand quicker deliveries and googlies.
He won lbw verdicts against Tanmay Mishra (6), Jimmy Kamande (2) and Odoyo (0) and ended Obuya's fun three short of a half-century going for one big hit too many.
Gul (2-12) rounded off proceedings with the opening delivery of the 34th over to complete a pleasing day for Pakistan, for whom the build-up to the tournament has been disrupted by the spot-fixing scandal.
