Just a week into the season, the Toronto Blue Jays starting rotation has been steamrolled with injuries of varying severity.

Right-handed starting pitchers Jose Berrios, Shane Bieber and Trey Yesavage all entered or suffered injuries during spring training.

The Blue Jays shut down Bieber before spring truly began with right forearm fatigue. Berrios was shut down in the spring due to a stress fracture in his throwing elbow and Trey Yesavage was shut down due to right shoulder impingement.

Yesavage was recently sent on a rehab assignment to the Single-A Dunedin Blue Jays on Friday.

Toronto suffered another loss to the starting rotation in a game against the Colorado Rockies on March 30 after tweaking his knee trying to field a ground ball.

It was revealed that Ponce suffered an ACL sprain and will miss significant time.

With all of those aforementioned pitchers out, the Blue Jays were all but forced to bring in another arm, which they did Friday.

According to a report on "X" from Sportsnet reporter Ben Nicholson-Smith, Toronto signed veteran left-handed pitcher Patrick Corbin to a one-year, $1 million deal that includes incentives for an additional $1 million.

Corbin, a two-time All-Star (2013, 2018) and one-time World Series champion (2019), is coming off a one-year stint with the Texas Rangers.

The 36-year-old lefty posted a 4.40 ERA and struck out 131 batters in 155.1 innings pitched across 31 appearances (30 starts) with the Rangers last season.

Corbin went through the entire offseason without being signed to a team but he reportedly stayed prepared in case a team called.

According to a follow-up report on "X" from Nicholson-Smith, Corbin has worked extensively this offseason and has already ramped himself up to 80 pitches. He was assigned to Dunedin after signing his deal and Nicholson-Smith said Corbin will possibly need just a "couple" minor league starts.

With the aforementioned injuries, the Blue Jays were down to a starting rotation of: Kevin Gausman, Max Scherzer, Dylan Cease and Eric Lauer.

Having Corbin, a veteran with 14 seasons of experience, will help the rotation weather the storm as other pitchers return. If Yesavage's rehab appearance coincides with Corbin's Toronto debut or soon after, the team could also opt for a six-man rotation to help avoid more injuries.

Currently, the Blue Jays will look to avoid a second-straight series loss in game two of a three-game set against the Chicago White Sox at 2:10 p.m. ET on Saturday.
