Shane Watson and Ahmed Shehzad knocked half-centuries to help Quetta Gladiators qualify for the playoffs with a comfortable eight-wicket win over arch-rivals Peshawar Zalmi in Abu Dhabi.
Watson smashed six sixes and as many boundaries in his undefeated 55-ball 91 while Shehzad scored a 45-ball 50 as Quetta overhauled a 166-run target in 17.4 overs.
Kamran Akmal cracked 50-ball 72 with seven boundaries and four sixes to help Peshawar to 165-4 after they were put into bat.
With the victory -- their sixth in 12 games against Peshawar in PSL history -- Quetta became the first team to make it to the year's playoffs. They have six wins in eight games and 12 points.
Peshawar are second with ten points in eight matches, having won five and losing three.
Watson and Shehzad added match-winning 129 runs for the second wicket as a formidable Peshawar pace attack found wickets hard to come by after Sameen Gul trapped Ahsan Ali for just one.
When Shehzad was dismissed, bowled by Umaid Asif, Quetta needed only 29 for victory. Rilee Rossouw gave Watson a good company during his four-ball 12 with one six and a boundary.
Peshawar's Hasan Ali failed to get a wicket after his 18 wickets made him the highest wicket-taker in the league.
When Peshawar batted they were given a brisk start of 38 by Kamran and Andre Fletcher who made 28-ball 26 with two fours and a six. But once Kamran was dismissed only Kieron Pollard found the scoring fast, smashing 21-ball 44 not out with seven fours and a six.
