Chicago targets veteran starter Seth Lugo to bolster their postseason rotation push. Kansas City seeks to restock farm depth with two high-upside prospects in this deadline mock trade.
As the July 31 trade deadline looms, the Cubs are primed to make their next move. With a strong lineup and Wild Card positioning, Chicago lacks a reliable mid-rotation starter. That makes Royals’ right-hander Seth Lugo, a crafty veteran with consistent sub-3.00 ERAs, an ideal target.
Meanwhile, Kansas City has slipped below .500 and could pivot toward a rebuild, using Lugo’s player option after 2025 as leverage. Here’s a closer look at how this trade could unfold—and why both sides stand to benefit.
Seth Lugo to Chicago to Upgrade Rotation Upgrade
Why it’s realistic:
Lugo has posted sub-3.00 ERAs across five of the last six seasons and ranks among Baseball’s best for limiting hard contact and stranding runners. He offers the Cubs a reliable, versatile arm who can slot into the No. 3 role and help stretch bullpen usage late in games.
Contract outlook:
He carries a player option post-2025, which limits the Cubs’ leverage but keeps the cost contained for this year’s race.

I’m unsure whether Lugo is available. He’s more expensive, but his prorated salary would be stomachable, and he brings familiarity while having a 2.94 ERA. Expected numbers aren’t enjoying Lugo this year as his contact quality has gotten rough. pic.twitter.com/rzYUdxFWvx

Royals Get Prospects to Push Rebuild
Facing a competitive hangover and with Lugo unlikely to return, Kansas City can convert him to two strong farm pieces: a high-ceiling pitching arm and a middle infield or outfield prospect to balance their rebuild.
Brandon Birdsell (RHP, Cubs Triple‑A)
Brandon Birdsell, a 2022 fifth-round pick out of Texas Tech, has emerged as a reliable right-handed pitching prospect in the Cubs system. At 25, Birdsell won the organization’s Minor League Pitcher of the Year in 2024, thanks to a 3.91 ERA and 134 strikeouts across Double-A and Triple-A.
He’s not overpowering, his fastball sits in the low 90s, but he mixes a solid curveball and slider with above-average command. Birdsell thrives on inducing soft contact and sequencing pitches rather than sheer velocity. After a lat injury slowed his 2025 start, he’s posted a 2.55 ERA through 17⅔ Triple-A innings, positioning himself as a high-floor arm with back-end starter or long relief potential.

Ronny Cruz (SS, Cubs Rookie League)
Ronny Cruz was selected 90th overall by the Cubs in the 2024 MLB Draft out of Miami Christian High School and quickly cracked the team’s top-10 prospect rankings. A lean, athletic shortstop with excellent bat speed and raw power, Cruz is already showing flashes of 20–25 home run potential.
He’s slashing .265/.311/.434 in the Arizona Complex League, demonstrating solid contact skills and athleticism for an 18-year-old. His plus arm and defensive tools project him as a long-term fit on the left side of the infield. While still years away from the majors, Cruz has the upside of an everyday contributor if his development continues on track.
Middle infielder Ronny Cruz has been stepping up his game recently both at the plate and in the field. Ronny was a 3rd round pick in the 2024 draft and is making good strides in the Arizona Complex League. #Cubs #CubsProspects #ACL2025 pic.twitter.com/l7glgwV6X7

-
Cubs: Add a veteran who complements their potent offense, potentially reducing bullpen overuse and improving consistency in late-season starts.
-
Royals: Convert a veteran nearing free agency into two controllable pieces, prioritizing long-term value over a short-term rental.
| Chicago Cubs Receive | Kansas City Royals Receive | Why It Works |
|---|---|---|
| RHP Seth Lugo | RHP Brandon Birdsell (Mid‑A prospect) | Cubs get a steady mid‑rotation arm; Royals receive controllable pitching depth. |
| SS Ronny Cruz (High‑A position prospect) | Adds high-upside infield talent to KC’s rebuild pipeline. |
This isn’t a blockbuster, but it’s a smart, balanced move. The Cubs bolster a rotation deficit without depleting their top-tier future assets. Kansas City maximizes return on a veteran likely to test free agency. With Chicago chasing a Wild Card or division push, and Kansas City resetting, this mock trade aligns both teams’ timelines and goals.
