The Cubs announced a series of roster moves, with Sahadev Sharma of The Athletic among those to relay the full slate. 

Right-hander Kyle Hendricks and left-hander Drew Smyly have each been placed on the 15-day injured list, Hendricks due to a lower back issue and Smyly due to a hip impingement. 

Right-hander Hayden Wesneski and left-hander Luke Little were recalled in corresponding moves. The club also designated Garrett Cooper for assignment and recalled Matt Mervis, a swap that was reported on earlier.

Hendricks, 34, has been out to an awful start this year. MLBTR’s Anthony Franco recently took a look at the righty’s struggles before Hendricks made his most recent start. 

As of right now, Hendricks has logged 21 innings this year over five starts. He has allowed 28 earned runs in that time, leading to an eye-popping earned run average of 12.00.

He’s never been a huge strikeout guy, but his 15.1% rate this year is lower than any season since his 2014 debut. It’s possible there’s some bad luck at play, with Hendricks having allowed a .392 batting average on balls in play. 

He’s also stranding only 50.3% of runners while a third of his fly balls have gone over the fence. His 7.75 FIP and 4.44 SIERA each suggest that he has deserved better, though to very different degrees. That’s due to FIP counting home runs as the pitcher’s fault, whereas SIERA gives more weight to batted ball data as opposed to actual results.

Hendricks is likely due for at least some normalization of his extreme results to this point in the season, but there will have to be a waiting period of at least a few weeks before the details of that correction are revealed. 

Per Meghan Montemurro of the Chicago Tribune, Hendricks felt his back bothering him before his start on Sunday and continued to feel it during the outing. The severity of the issue isn’t clear, but he’ll have to miss at least a couple of weeks.

The Cubs will now have to figure out who joins the rotation alongside Shota Imanaga, Jordan Wicks, Jameson Taillon and Javier Assad. Tonight marks the start of a stretch where they play 16 games in a row before their next off-day. 

Smyly has plenty of starting experience and could have been a candidate for such a job, but he’s now on the IL himself.

Wesneski has been working in a swing role for the club in recent years and could perhaps make a few starts. Ben Brown has been pitching multi-inning stints this year and would be another option. 

Veteran Julio Teheran was signed to a minor league deal last week and gives them a non-roster option. Due to Cooper being designated for assignment, there’s now an opening on the 40-man roster.
