Azhar Ali and Shan Masood struck fifties before Pakistan declared on 261-3 on day one of their tour match against Worcestershire, at New Road.
The pair, yet to hit a half-century between them in the Test series with England, gained some valuable batting practice on Friday ahead of the third Test at Edgbaston, which begins on Wednesday.
Stand-in skipper Azhar – who averages just 9.75 in four Test innings against England this summer – led the way with 81, striking 10 fours and one six in his 140-ball innings.
Meanwhile Masood, whose series average is scarcely better at 17.75, gained a little confidence with 67 off 149 deliveries.
Fringe players Iftikhar Ahmed (41no) and Mohammad Rizwan (49no) shared an unbroken fourth-wicket stand of 80 before the declaration came.
Alex Kervezee (1-38), Alex Hepburn (1-49) and Ed Barnard (1-30) all took a wicket each for Worcestershire, who have lost their last two Royal London One-Day Cup matches this week.
In response, the hosts – who won the toss and put Pakistan into bat – closed on 30 without loss from 11 overs with Daryl Mitchell and Tom Fell both unbeaten on 14.
