Swashbuckling opener Alex Hales cracked his maiden century to lift England to 283-5 in the second day-night international against Pakistan in Abu Dhabi on Friday.
The right-hander scored 109 off 117 balls studded with seven boundaries and three sixes after England won the toss and decided to bat at Sheikh Zayed Stadium.
Hales added 102 for the first wicket with Jason Roy (54) and another 114 for the second with Joe Root (63) as England, seeking to level the four-match series after losing the first game, put up a challenging total.
England were off to a confident start on a pitch used for the second match in a row, as Roy and Hales lifted the tempo after the first ten overs.
Root added 40 for the third wicket with Eoin Morgan (29) before Riaz returned for his second spell to hit Root's leg stump with a slower one.
Jos Butler was cleaned up by Riaz for 11 as England managed just 27 runs in the last five overs.
