The White Sox announced Monday that they’ve claimed left-handed reliever Josh Osich off waivers from the Orioles. In order to make room on the 40-man roster, Chicago has placed right-hander Michael Kopech on the 60-day injured list. Osich, 30, was designated for assignment by Baltimore last week. Kopech, meanwhile, is expected to miss the entire 2019 season after undergoing Tommy John surgery late in the 2018 campaign.

Osich, 30, has spent time with the Giants in each of the past four seasons, though he’s struggled increasingly at the MLB level dating back to 2016. In 120 1/3 innings, Osich has a 5.01 ERA with 7.9 K/9, 4.6 BB/9, 1.50 HR/9 and a 51.8 percent ground-ball rate. Last year in Triple-A, Osich posted a 4.96 ERA with a 42-to-18 K/BB ratio in 45 1/3 innings.

Osich does have a minor league option remaining, and he’s also averaged roughly 95 mph on his heater throughout his career. Right-handed batters have owned him at the MLB level (.294/.385/.496), though he’s held lefties to a more manageable (albeit still unspectacular) .228/.319/.388 line in his time as a big leaguer. San Francisco designated Osich for assignment a month ago when they acquired young righty Jose Lopez from the Reds, after which he was claimed by the Orioles. Osich’s time in the Baltimore organization lasted only about three weeks, as the O’s designated him Friday upon picking up Dwight Smith Jr. from the Blue Jays.
