Yeah, I'll say there's some legitimacy to Charlie Morton's 2.80 ERA over his last seven starts. Anyone who doesn't isn't paying enough attention. He had a 2.67 ERA over his final 11 starts last year as well.
But what isn't legitimate are his 9.8 strikeouts per nine innings during that stretch. Like most ground ball pitchers, he's not a bat-misser, having never averaged even 7.0 strikeouts per nine innings in the big leagues. At least up until recently, he aimed for quick outs by pitching to contact, trusting it would be weak enough to result in an out. It's the M.O. of pitchers like Tim Hudson, Henderson Alvarez, Mike Leake and Kyle Gibson, and it certainly has its place in Fantasy.
Of course, more contact by its very nature yields more hits, so the downside to a ground ball specialist is a high WHIP relative to the ERA and, of course, a low strikeout rate. I'm not willing to suggest that after seven starts Morton has reinvented himself, so he's just as susceptible. It's enough to make him an iffy option in mixed leagues most weeks, though like Leake, you'll want to keep him around for the two-start weeks.
