Toronto Blue Jays have placed left-hander Hyun Jin Ryu on the 10-day injured list with left forearm inflammation, it was announced Sunday.

Ryu received an MRI Sunday morning after experiencing soreness during Saturday's start against the Oakland Athletics.

Left-hander Ryan Borucki (right hamstring strain) has been activated from the injured list and will be active for Sunday's series-finale against the A's.

Ryu was roughed up for five earned runs and six hits in four innings while striking out just one hitter. The big blow came in the third inning when Sean Murphy launched a 452-foot home run to left centre field to put the A's up 5-1.

After struggling down the stretch of last season, Ryu has opened 2022 with a pair of clunkers, allowing six earned runs in 3.1 innings last weekend against the Texas Rangers. 

The Jays' southpaw has a history of arm injuries, suffering from a torn labrum during the 2015 season and undergoing an elbow debridement procedure the year after while with the Los Angeles Dodgers. Ryu missed all of 2015 and started just one game in 2016.

The 35-year-old is in the third season of a four-year, $80 million contract he inked with the Jays in December of 2019.

The Blue Jays will head to Fenway Park to take on the Boston Red Sox in a three-game set beginning on Tuesday.
