Luke Gregerson has now struck out all six Mets he’s faced in his two innings of relief in this series.

Our video editor Jason directed my attention to Gregerson’s ridiculous season today, and it’s probably something worth noting.

The 26-year-old right-hander has now struck out 39 batters in 32 1/3 innings while walking only two. That’s a 19.5:1 0 K:BB ratio, if you’re not good at math. Oh, and one of those two walks was intentional.

He has allowed six runs this season, good for a 1.39 ERA. And, most amazingly, he has only allowed 12 hits this entire season. Dude has a 0.433 WHIP. No other pitcher with double-digit innings this season has allowed less than half a baserunner per inning.

Gregerson throws more sliders than any other pitcher in baseball according to Fangraphs.com, which means he’s probably an injury risk.

But considering the Padres got Gregerson as a player-to-be-named later from the Cardinals in exchange for Khalil Greene, it’s safe to say that was a decent pickup. Greene hit .200 with a .272 on-base percentage in 193 plate appearances with the Cardinals in 2009, a season in which he struggled with social anxiety disorder.

What’s funny — or maybe not funny at all, just telling — are the parallels between Gregerson and Padres closer Heath Bell. Both posted excellent peripherals in the Minor Leagues, though both were always a little old for their level. Neither got much of an opportunity with the team that drafted him, and both came to the Padres as low-cost trade acquisitions. Hmph. Maybe that Kevin Towers guy knew a thing or two about building a bullpen.
