The Chicago Cubs optioned Javier Assad to Triple-A Iowa on Sunday, August 16, to clear a roster spot for Dominican starter Edward Cabrera, who was returning from the IL after nearly eight weeks out with a left hamstring strain. It looked like a tough break for the Tijuana native, who headed to Iowa with a 6-1 record and a 3.59 ERA. Turns out, he barely had time to unpack: ESPN reported just 19 hours later that the Cubs were calling him right back to start Tuesday, August 18, against the Tampa Bay Rays.
A Move That Was Supposed to Last Weeks — Not Hours
On Sunday afternoon, reporter Bruce Levine of 104.3 The Score confirmed the option. On paper, the roster move made sense. Cabrera had spent nearly eight weeks on the IL and had worked his way back with 11 strikeouts over 5.2 combined rehab innings before throwing five clean innings with seven strikeouts at Double-A Knoxville on August 11. The Cubs needed the active roster spot. Simple enough.
What nobody saw coming was what happened next. Matthew Boyd went down with biceps discomfort, and Cade Horton landed on the IL with a forearm issue. Suddenly a rotation that was already posting the fourth-worst combined ERA in the league at 4.29 in 2026 had a gaping hole in it. Assad was the obvious answer.
Why Assad Is Still the Most Reliable Arm in That Rotation
The 6-1 record and 3.59 ERA don’t tell the whole story — but the 1.12 WHIP across 80.1 innings in 21 appearances (10 starts) does a pretty good job of filling it in. Assad has functioned as a swingman all season, sliding between starter and long reliever depending on what the Cubs need. For context: Cabrera, the guy Assad temporarily made room for, owns a 5.10 ERA in 14 starts with Chicago this year — a far cry from the 3.53 he posted with the Miami Marlins in 2025.
The Statcast numbers back up the trust manager Craig Counsell has placed in him. According to Baseball Savant, Assad allows an average exit velocity of 90 mph — the lower, the better — and a barrel rate of just 7.4%. His walk rate sits in the 81st percentile across MLB: only 21 free passes in 80.1 innings, a BB% of 6.5%. He doesn’t miss a ton of bats, but he rarely lets anyone hit the ball hard.
There is one number Cubs fans should keep in mind when reading his season: Assad’s xERA is 4.63, reflecting the quality of contact he’s allowed. The gap between that 4.63 and his actual 3.59 suggests some good fortune on hit timing — or that his defense has bailed him out more than usual. Either way, he remains the arm the organization reaches for first when they need a stretched-out starter ready to go.
Historically, Assad is already the all-time Cubs leader in wins, innings pitched, and games played among pitchers born in Mexico. A brief trip to Iowa doesn’t change that.
What’s Next for Assad and the Cubs’ Rotation?
With the recall confirmed for Tuesday, Assad would make his 11th start of the year against the Rays. The Cubs are in the thick of the NL Wild Card race, and their rotation has combined for just 3.9 fWAR in 2026 — fourth-worst in the majors. Whether Assad returns to his swingman role or slots in as a permanent rotation piece will depend heavily on the health of Boyd and Horton.
Back in May, when Assad was optioned for the first time, Counsell explained that the goal was to keep a stretched-out arm available as an emergency starter. In August 2026, that plan is working exactly as designed — Assad as Chicago’s pitching insurance policy. This time, the policy paid out in under 24 hours.

Assad doesn’t overpower hitters — he just makes them hit it softly and often at someone. In a rotation running on fumes, that’s exactly what Chicago needed. And they figured that out in less than a day.
