BALTIMORE — Boston Red Sox left-hander Eduardo Rodriguez was placed on the 10-day disabled list Friday after reinjuring his knee on a fall from the bullpen mound.

Rodriguez slipped off the mound during the latter stage of his warmup for Thursday night’s start against the Baltimore Orioles. He declared himself OK but ended up allowing a career-high tying four home runs in Boston’s 7-5 loss.

“We put him on the disabled list after some swelling emerged overnight,” Manager John Farrell said.

Rodriguez missed Boston’s first 51 games last year while on the disabled list with a right patella (kneecap) subluxation.

To fill the spot on the 25-man roster, the Red Sox recalled right-hander Brandon Workman from Triple-A Pawtucket.

MARINERS: Seattle placed shortstop Jean Segura on the 10-day disabled list with a right high-ankle sprain. Designated hitter Nelson Cruz won’t be joining him on the DL despite being hit on his left hand by a pitch.

Manager Scott Servais said it would probably be a week before Segura is re-evaluated. Segura is tied for the AL lead with a .341 batting average.

RANGERS: Sam Dyson was designated for assignment after the latest loss by the former closer.

Texas made the move two days after Dyson gave up two home runs and three runs in the 10th inning of a loss to Tampa Bay. It was the sixth loss of the season for Dyson. He was removed from the closer role in early May, and has blown all four of his save chances this season.

BRAVES: Atlanta activated left-hander Eric O’Flaherty and infielder Adonis Garcia off the disabled list.

Atlanta also called up infielder Johan Camargo from Triple-A Gwinnett. He’s in his third stint with the Braves.

PIRATES: Pittsburgh optioned infielder Gift Ngoepe to the minor leagues about a month after he debuted as the first African-born player – from South Africa – in the majors.
