What is C BROWN UP TO?

[golfer]

Based on the Thorograph figures:

Silver Timber was consistently running 5's and 6's from age 3 to age 5.
In this 6 yr old gelding's first start this year he ran a 5. Was then claimed from Linda Rice, and in his 1st start for Chad Brown, ran a 2. Unless yesterday's course was playing EXTREMELY fast, he improved off that 2. Someone more knowledgeable than I, please tell how normal it is for a 6 yr old to run lifetime best races back to back, after being claimed from a trainer who is far from incompetent (to say the least)?
