Oh, he's our #2 starter, not much doubt about that. But, I say again, he's our #2 largely because Price has been on the DL for big chunks of the season and came back too late to be a viable starter in the postseason. Porcello stinks this season despite the Cy Young last year. All those dingers are the result of his over-reliance on the fast ball and his inability to keep the ball low in the strike zone in an era when those shifts almost guarantee outs if the batter will hit a grounder. I think ERod right now is a better pitcher than Pom but agree he hasn't proven it yet. Lately, he's been pretty darn good, but, sadly, that could vanish. Heck, I still like Fister, but these days that's a hard sell.
Right now, despite my grievances about Pom, I think he is a sure starter in the first 3 games of the ALDS. If ERod gets another good start and Pom fumbles his next, maybe ERod is the #2. Porcello is still #4. And I'm not sure what happens to Fister.
And thank goodness Price right now represents a pretty good long reliever--say, 3 innings, maybe 4--if one of the starters falters.
