Just cannot get the big hit with the bases loaded. Segura got a little hit with the bases loaded to get a run in, but a long ball sure would have looked good to follow that up. I do, however, agree that the 3-1 and 3-2 pitches were not in the strike zone, but were close. I am sure Harper wanted to get the big hit but yes, a walk is another run and would have looked good.
Regardless, 3-1 lead going to the bottom of the 8th. Need six outs.
