Fitness was probably the difference.
Pretty even game till halftime, but Knights went up a few gears in the second half and Penrith were out on their feet for the last 15 - letting in at least 3 soft tries.
Lost 20 - 16, but the boys gave it everything for the last 5 minutes and nearly scored 3 times.
They'll be a bit more serious in the first half next week.
Knights hold on to win and will play Souths in the preliminary final next week. Better performance than last week but still not at their best. Rostron has been very quiet through the 2 finals.
