The Cubs are promoting Wiggins from Double-A Knoxville to Triple-A Iowa on Wednesday, Andy Martinez of Marquee Sports Network reports.
The 23-year-old is one of the organization's top prospects and will move up to the highest level of the minors after posting a 1.93 ERA, 0.90 WHIP and 52:17 K:BB over 42 innings (10 starts) at Double-A. Wiggins opened the 2025 campaign with High-A South Bend and is now just one step away from the majors, though he isn't likely to make his MLB debut until 2026.

Cubs' Jaxon Wiggins: Missing in action
Rotowire
Wiggins hasn't pitched for Double-A Knoxville since July 19.
Marquee Sports Network reported that Wiggins wouldn't pitch in the Futures Game and would instead rest for a month before returning July 19. Indeed, Wiggins didn't pitch between June 20 and July 19, but it didn't seem to be part of the plan to shut Wiggins down after his two-inning appearance on that date. Wiggins threw 59.2 innings in 2024, his first year back from Tommy John surgery, and he is up to 62.1 innings this season. The 23-year-old righty has always had great stuff, and this year his control improved enough (10.4 BB% at Double-A) that he has a real chance of making it as a starting pitcher.

Cubs' Jaxon Wiggins: Showing improved control
Rotowire
Wiggins, who has a strong 2.25 ERA across 36 innings for Double-A Knoxville this season, has benefitted from improved control and a new pitch in his repertoire, Jordan Bastian of MLB.com reports.
Wiggins posted a 12.4 percent walk rate at High-A South Bend earlier in the year and has lowered that to 10.4 percent since his promotion to Double-A in May. While still a bit high, it's down from the 14.2 percent mark he posted across three levels in 2024. The 23-year-old righty is still touching the upper 90s with his fastball as well, and he's worked in a spiked curveball grip that's given him better control than he previously had with his slider. Wiggins has already struck out 48 batters in his 36 innings for Knoxville, and at this rate, he could move on to Triple-A in fairly short order. The youngster has become the Cubs' clear top pitching prospect and could debut early next year if he continues to show improved control.

Cubs' Jaxon Wiggins: Missing bats at Double-A
Rotowire
Wiggins has a 2.25 ERA, 0.97 WHIP and 48:15 K:BB in 36 innings through eight starts for Double-A Knoxville.
A 6-foot-6 righty who came into the year with big stuff and significant bullpen risk, Wiggins' 10.4 percent walk rate at Double-A is his best mark since he had a 6.3 percent walk rate at Single-A in 2024. Even with his improved control, drawing a walk against Wiggins is as good of a proposition as trying to get a hit, as he's issued 12 walks while allowing 10 hits over his last six starts and has a .150 batting average against this season. He boasts an upper-90s fastball and can touch triple digits, and he also wields a plus slider and solid changeup.
