The Cubs are going to welcome right-hander Jameson Taillon back from the injured list today, which will bump fellow righty Javier Assad to the bullpen, per Sahadev Sharma of The Athletic. Sharma also lists Michael Soroka as someone who could help the bullpen down the stretch, suggesting he’ll likely end up in a relief role when he comes off the injured list.
Assad, 28, was a solid member of the Chicago rotation last year. He made 29 starts, allowing 3.73 earned runs per nine innings. His 19.4% strikeout rate and 9.9% walk rate were a bit worse than league average but he had a decent 43.6% ground ball rate. He may have benefitted from a high strand rate of 80.3% but his 4.64 FIP and 4.72 SIERA still pointed to him being capable of passable work as a big league starter.
But this year has been challenging. Oblique issues kept him on the injured list until August. He has since made five starts with a 4.62 ERA. His walk rate and grounder rate have improved in that small sample but he has only struck out 13.2% of opponents.
It’s not a drastic drop-off overall but the Cubs don’t feel Assad is one of their five best rotation options. When Taillon returns, he will slot in alongside Matthew Boyd, Shota Imanaga, Cade Horton and Colin Rea. Boyd and Horton are both having really strong seasons. Imanaga isn’t pitching as well as last year but has still managed to post a 3.21 ERA. Rea and Taillon are solid back-end options with ERAs of 4.20 and 4.15 respectively.
Assad will therefore end up in the bullpen, likely in long relief. The Cubs already have guys like Aaron Civale and Ben Brown capable of soaking up multiple innings from the bullpen but Assad will give them one more.
As for Soroka, his potential bullpen move is logical and should be more impactful. He had a lot of success in a relief role last year. He started 2024 in the White Sox’ rotation but ended up getting bumped to the bullpen. He finished out the year with 36 relief innings with a 2.75 ERA and 39% strikeout rate. His 13% walk rate was certainly high but that kind of strikeout stuff made him an intriguing leverage relief option this winter.
He came into 2025 still with the hope of being a starter. He signed a one-year, $9MM deal with the Nationals and joined that club’s rotation. He had a decent 4.87 ERA, 25.4% strikeout rate and 7% walk rate with Washington, though notable splits later in games. This year, he has held opponents to a .193/.250/.329 line when going through the order for the first time. That line jumps to .218/.302/.395 the second time through and then there’s a big spike to .319/.467/.574 for the first time through.
The Cubs acquired him at the deadline even though his velocity had been trending down throughout July. They nonetheless hoped to get a few starts out of him. But he made just one, lasting two innings, before a shoulder strain put him on the shelf. In his recent bullpen sessions, his velo has been back up to the mid-90s. He’s set to go on a rehab assignment this week and could rejoin the big league club soon.
Given last year’s bullpen success, his third-time-through-the-order penalty and recent health concern, a bullpen move makes lot of sense. If he can posts some results similar to last year’s, he could jump into a leverage role. That would help the Cubs going into the stretch run, as they recently lost Daniel Palencia and Ryan Brasier to the IL due to a shoulder strain and groin strain respectively.
