The Houston Astros placed right-hander Lance McCullers Jr. on the 15-day injured list with a sprained right foot Monday before his scheduled start against the Athletics.

McCullers has made seven starts this year in his return after missing two full seasons with various arm injuries.

He is 1-2 with a 4.91 ERA this season. He allowed four hits and four runs while striking out six in five innings of a 4-2 loss to the White Sox in his last start on Tuesday.

The injury to McCullers is the latest in a string of injuries to the Astros rotation. Starters Hayden Wesneski and Ronel Blanco are both out for the season after having Tommy John surgery and right-hander Spencer Arrighetti has been sidelined since April after breaking his right thumb in a batting practice mishap.

They also are missing right-handers Luis Garcia and Cristian Javier, who are both still recovering from Tommy John surgery.

Longtime pitcher Taylor dies: Dr. Ron Taylor, a World Series champion pitcher with both the St. Louis Cardinals and New York Mets who later became the Toronto Blue Jays’ team physician, died Monday. He was 87.

Taylor died in Toronto after a long illness, the Mets said in a statement.

A native of Toronto and a member of the Canadian Sports Hall of Fame, Taylor was part of the 1964 Cardinals’ and 1969 Mets’ championship teams.

The right-hander pitched for the Mets from 1967-71. In 1969, he led the Miracle Mets with 59 appearances and 13 saves to go with a 9-4 record and 2.72 ERA.

Taylor pitched 2 1/3 scoreless innings in the 1969 World Series and saved a 2-1 victory in Game 2 against Baltimore. Against Atlanta in the NL Championship Series, he saved Game 1 and earned the win in Game 2.

His big league career spanned 11 seasons, beginning with Cleveland in 1962 and ending with San Diego in 1972. He also pitched for Houston from 1965-66 and finished 45-43 with a 3.93 ERA and 74 saves in 491 games, including 17 starts.

After baseball he enrolled in medical school and spent about three decades as the Blue Jays’ team physician.
