The Tremlett and Andrew innings were completely different, one was a fun quick slog in a dead game and the other was proper cricket shots to build a huge total. Lets remember that Gareth Andrew came in at almost exactly the same position as Walters did for Surrey. Played sensibly to reach 50 off 41 balls and then powered on to 100 in only 17 more.
The oval is one of the largest playing surfaces in England and all of Andrews sixes cleared it with ease. Maybe he could have hit the ball further but that might have compromised the timing of the shot or made him loose his shape which could easily mean his mis hit or even missed the ball. You don't get any more runs for hitting the ball 20 rows back than you do for it only just reaching.
Because no-one cares about Fearnley!
