4 backup plans the Cubs could turn to in the wake of Shota Imanaga's injury

3. Use Keegan Thompson in the bullpen

Before the start of the season, the Cubs designated right-handed reliever Keegan Thompson for assignment, but he cleared waivers and opted to stay with the organization. And the former starter has quietly put together a solid first month with the Iowa Cubs.

The 30-year-old has compiled a 2.41 ERA and struck out 27 batters over 18.2 innings pitched. Notably, Thompson has been going longer in his relief outings and started three games, including in his last appearance on Friday. In that game, Thompson tossed four innings while only surrendering one earned run.

In the scenario of the Cubs calling up Thompson, it seems like he would be used out of the bullpen as the swingman and Flexen gets used as a starter. Or they could try Thompson in the rotation first, whichever makes more sense. Using Thompson would mean clearing a 40-man roster spot, but it might be worth it if Imanaga goes on the IL and Thompson has plenty of experience in the bigs (227.1 innings).

4. Give Jordan Wicks another shot

The other option would be calling up Jordan Wicks, but the southpaw has been completely ineffective for both Triple-A and the Cubs. Wicks gave up seven earned runs and two home runs in his last start on May 1. After allowing six hits and five earned runs in his two games with the Cubs this year, and immediately getting sent back down, it seems unlikely he will get another call until he strings together some good outings.
