Mohammad Yousuf's reputation as a world-class cricketer is at stake, according to Pakistan's associate manager Shafqat Rana.
Yousuf made an impressive 55-minute appearance at the crease during a rain-ravaged opening day to the tourists' two-day match against Worcestershire at New Road.
The 35-year-old struck an undefeated 40 in his side's total of 112 for 2 off 28.1 overs. He faced 54 deliveries and struck eight fours as part of his preparations for Pakistan's third Test against England, which starts at The Oval next week.
Rana said: "Yousuf has been working hard for the last week or so. He's mentally stronger now and it was his decision to get out of retirement and play for the country again. He is stronger and his reputation is at stake now. He's a world-class cricketer and we want him to bat for a long time."
