Red Sox starter Rick Porcello has struggled most of this season, but I like him as an underdog Saturday against the Astros. Houston is going with fill-in starter David Paulino, who was rocked for five runs on six hits against the Angels while failing ot get out of the fifth inning. Boston also has won Porcello's last five Saturday's starts. Houston is starting to fade after its fantastic start and this is a value fade spot.
