In that match, Shapiro ran out of space at :30 to get the reversal, and then escaped at 1:00. He then rode the entire third period, so not much gassing there.
In their third match (3rd place match at NCAAs), Cardenas rode him for about :27 in the third period before cutting him. No more scoring in the last 1:30, so either both or neither of them had gassing issues.
