Good old fashioned pitching duel. Rosenthal hitting 101 on the gun while striking out the side in the 9th.
Also, I can't believe that MLB would start a game that time of day with the sun/shadows the way they were. This is the NLCA for gosh sakes. I understand that the WORLD wants the Red Sox in prime time, but the first 3-4 innings were brutal for the batters.
