Raza took upon himself the responsibility of giving direction to the innings with a magnificent 137 to help Pakistan 'A' close out the day at 256 for six.
Raza came to the wicket with the Pakistan 'A' in a spot of bother at 69 for three after Zimbabwe 'A' Stuart Carlisle won the toss and put the visitors in.
The 23-year-old lad clubbed 17 boundaries and five sixes in his knock of 137 and was associated in a fighting 62-run fourth-wicket stand with skipper Misbah-ul-Haq in pulling Pakistan 'A' out of the rut.
Misbah played an enterprising innings scoring 33 and struck six fours.
But it was the sixth wicket stand between Raza and wicket-keeper Zulqarnain Haider that enabled Pakistan 'A' to wrest the initiative.
Haider may have scored just 12 but his long haul at the wicket was crucial as the pair strung together a 125-run partnership with Raza doing bulk of the scoring.
Brief Scores: Pakistan 'A' First Innings: 256/6.
