At times, Joe Kelly has shown flashes of being a very good MLB pitcher. Other times, not so much.

The Boston Red Sox right-hander has a 1-2 record with a 6.35 ERA through six starts this season. Those numbers aren’t great, but they’re mostly the result of a few rough innings. Outside of that, Kelly has put together some pretty impressive performances, including a seven-inning gem against the New York Yankees in his season debut.

So what’s the key to success for Kelly? Eliminate the bad innings and deliver more of the good ones.

“There’s been an inning probably inside of each outing where it’s maybe come back to bite him a little bit,” Red Sox manager John Farrell told reporters Thursday before Kelly’s start against the Seattle Mariners. “No denying the stuff; when he uses a full complement of pitches is when he’s been most efficient. Looking for more of that tonight.”
