He got stronger in the middle of the tournament. Essentially the same way he leveled up fighting Cell.
Gohan's whole thing is infinite potential, but zero motivation to improve himself. The ToP motivated him to keep leveling up until he reached Kefla level, who herself was theoretically above Goku Blue (On account of the fact Kale alone was, and Whis claimed Kefla was stronger then anyone on the field at the time, which included Goku Blue and Vegeta)
