Red Sox roster move: Who’s Bailey Horn, newest member of 26-man?

BOSTON — The Red Sox recalled left-handed reliever Bailey Horn from Triple-A Worcester on Friday.

Boston already optioned right-handed reliever Isaiah Campbell and catcher Tyler Heineman to Triple-A Worcester on the day off Thursday. It activated Connor Wong off the paternity list as well.

Who’s Horn? This will be his first major league stint. MassLive profiled him in May after Boston acquired him from the White Sox on April 30.

Horn has a fastball up to 97 mph.

“The fastball is a good one,” manager Alex Cora said. “He’s been throwing strikes, too. So with them, they’ve got a bunch of lefties and switch-hitters so it made sense to go this route.”

The Red Sox have encouraged him to throw his cutter more often. The results showed at Worcester where the 26-year-old allowed three earned runs in 16 innings (1.69 ERA). Opponents batted just .167 against him. He struck out 19 and walked nine.

He calls his cutter “a cutter/gyro.” He has a big sweeper and a “harder and smaller” slider that provides a different look.

“It’s just a good pitch,” Horn said about the cutter. “It plays off the heater. Just a good pitch to keep the hitters off the four-seam. And then you can go off the cutter as well with different offspeeds: slider, curveball, sweeper.”

He added about his four-seamer, “Throwing it for a strike in the zone and then just staying behind it and letting it play. Just having it carry through the top of the zone, even the bottom of the zone.”
