It's like when Price starts for the SOX. The opposition is probably thinking OK, we're not going to get many runs off of him, but after the 5th inning, we should score plenty.
Rick's career ERA is 4.31 and his WHIP is 1.309. These are mediocre at best. The best that can be said about Porcello is his durability. Btw, no starter on the SOX over Rick's time here has had as much run support as he has.
