If not for a dominant start June 25 against the Braves in which he recorded nine strikeouts in seven innings, Collin McHugh probably wouldn't be owned in 54 percent of leagues. While his overall numbers still look good, he hasn't had anything else to hang his hat on since early June. Over his last six starts, he has a 4.45 ERA, 1.33 WHIP and -- here's the killer -- 5.3 walks per nine innings.
Still more than a strikeout per inning, but the Braves are partially to credit for that. They strike out against everybody. Plus, the strikeouts work with the walks to drive up McHugh's pitch count, limiting his quality starts and leaving the bullpen to pick up his victories -- that is, when he pitches well enough to put it in position to do so.
Of course, a six-start trend doesn't condemn a pitcher to being a certain way forever and ever, but for a pitcher who came out of nowhere like McHugh did this year, it's reason for suspicion.
The odds are against him making a significant Fantasy impact pitching for the Astros anyway, so you might want to look into other options.
