Clay Buchholz has been making quick work of opposing hitters this spring.

Never mind that Buchholz has allowed only one run in 131⁄3 innings over four spring training starts. The most impressive thing about the right-hander has been the faster pace at which he has worked, a point of emphasis for several Red Sox starters under the tutelage of new pitching coach Juan Nieves.

“The pace of the game is big for me,” Buchholz said after allowing nothing more than a solo homer to Pirates second baseman Neil Walker over five innings in the Red Sox’ 4-3 loss. “That does a lot to help me. It’s more just, get the ball and get a pitch and throw it and take all the thinking out of it. It’s been particularly one of my problems that whenever something hits the fan, I slow the game down and make sure I’m doing the right thing, and sometimes that might hurt me more than it’ll help me.”

Left-hander Jon Lester also has discussed the Sox’ goal of pitching with a better tempo. Nieves brought over the philosophy from the Chicago White Sox, where pitching coach Don Cooper stresses it to his pitchers, and has been preaching it to Lester, Buchholz and Felix Doubront. Buchholz also said veteran right-hander Ryan Dempster, who signed with the Red Sox in the offseason, has set an example for working quickly.

Manager John Farrell also has offered his endorsement. As the Blue Jays manager last season, Farrell noticed Red Sox pitchers tended to work at a snail’s pace, especially with runners on base. He suggested the trend may have started when he was the Sox pitching coach and Josh Beckett and Jonathan Papelbon were notorious for taking their time on the mound.
