BOSTON (AP) — One run was all the support Clay Buchholz needed to lead the Boston Red Sox out of a three-game skid and put a dismal month of May behind them.

Rusney Castillo’s RBI single in the seventh broke a scoreless tie and Buchholz pitched eight strong innings in a 1-0 shutout of the Minnesota Twins on Tuesday night.

Buchholz stuck out eight and allowed three hits and walked two against the Twins, who swept Boston last week in a three-game series at Minnesota.

“It’s not fun getting swept by any team. We knew that this was going to be a big series,” said Buchholz, who took the loss exactly one week before when the Twins edged the Red Sox 2-1.

Buchholz (3-6) said he and the Red Sox hadn’t forgotten the sweep, but he was still recovering from a weekend illness and wasn’t up for a complete game on Tuesday.

Koji Uehara took over in the ninth and picked up his 11th save to preserve the shutout.

“I was gassed and I’d rather give Koji a clean inning to work with,” Buchholz said.

Mike Pelfrey (4-2) had a solid start as he and Buchholz both carried a shutout into the seventh inning, when the Red Sox broke the tie. Xander Bogaerts hit a two-out double off the wall in center and scored easily on Castillo’s single up the middle.
