Joe Kelly has been a bit up and down this season, but there’s no doubt that Thursday’s performance fell into the former category.

The Boston Red Sox right-hander came up big against the Seattle Mariners, allowing just one run over 6 1/3 innings in his team’s 2-1 win at Safeco Field. The effort certainly was a promising one for Kelly, who had allowed five earned runs or more in each of his previous four starts.

Part of Kelly’s key to success Thursday was to take a little heat off his fastball and focus on pitch location. Clearly his strategy worked, and he talked about the results after the game.

“I felt good. Felt strong,” Kelly told reporters. “I made some pitches when I had to. I feel like I’m getting better out there, and I put a lot of emphasis on fastball location today. That’s what I went out there with, and tried to hit every spot I could with my fastballs.”
