May I ask what kind of data have you analysed and how many matches have you observed to come up with a judgement like that? Saini hasn't even played 10 matches all format combined for crying out loud. In this match he started off ordinary, gave 10 runs in his first, then picked up his pace and Lankan's were all at see, almost 45% of his deliveries were over 145kph and they really struggled to put bat on ball.
Bumrah was a bit rusty which is understandable coming from a long injury, still kept it tight, conceded 12 in his last over that somewhat messed up his numbers today. He does extensive pace variation so his average speed sometimes takes a hit but he generally can clock up to 147-148. Today his fastest was around 146k.
