Both these teams have recently registered impressive victories over big contenders so their tails must be up.
Lahore, for instance, ended the unbeaten run of Multan Sultans in an impressive 52-run victory. They had to again thank their red-hot opener Fakhar Zaman for the win.
The lefty has been in incredible form this PSL and has not had a single failure in six outings. In fact, he has now become the first batter to score 35-plus runs in six straight matches.
Against Multan, his blistering 60 off 37 balls laid the foundation of a 182-run total before a superb bowling effort saw them skittle the defending champions for just 130.
Early indications are that Lahore will prove to be a hard side to beat in Lahore.
Most people had ruled Quetta Gladiators out of the tournament and were already thinking towards the next year. But like the Lazarus, the Sarfaraz Ahmed-led unit has risen.
Back-to-back wins over two bona fide contenders has given Quetta all the momentum and now the title race appears to have four horses.
Their latest win, over Islamabad United, also came in a successful run chase of a big total. And the man to thank for it was none other than their captain Sarfaraz, who expertly guided the chases with an unbeaten 50 off 32.
In a matter of days, Quetta have become the most scary unit in PSL and teams would be wary of facing them.
