Red Sox right-hander Walker Buehler returned to Boston on Thursday to have tests on his sore right shoulder and won’t start against the Minnesota Twins tonight, manager Alex Cora said.

Buehler is 4-1 with a 4.28 ERA in his six starts since signing a one-year, $21.05 million contract with the Red Sox last December. He allowed three runs and seven hits in six innings to beat Cleveland last Saturday, his third straight winning start.

Before joining Boston, Buehler went 47-22 and won two World Series titles in seven seasons with the Dodgers.

Right-hander Brayan Bello will start in Buehler’s place. Bello is 2-0 with a 3.27 ERA in two starts since being activated off the injured list because of a strained shoulder.

Red Sox rookie second baseman Kristian Campbell was scratched from the series finale against the Blue Jays in Toronto on Thursday because of right rib discomfort.

Campbell is batting .301 with four homers and 12 RBIs in 29 games. He signed a $60-million, eight-year contract with Boston on April 2, less than a week after making his big league debut.

IL MOVES

The Texas Rangers placed catcher Kyle Higashioka on the 10-day injured list with a mild left intercostal strain.

Higashioka, who signed a two-year deal with Texas in December, is hitting .254 with a homer and eight RBIs in 17 games.

The Arizona Diamondbacks placed reliever Justin Martinez on the 15-day IL with right shoulder inflammation, a day after after his velocity dipped while he failed to record an out against the Mets.

Martinez is 1-1 with a 2.70 ERA and three saves in 12 appearances this season.

The New York Yankees transferred outfielder/designated hitter Giancarlo Stanton to the 60-day injured list.

Stanton is rehabbing from torn tendons in both of his elbows and hopes to be back sometime in June.
