The Kevin Gausman Cubs trade has officially kicked off Toronto’s deadline sell-off. The Blue Jays were mid-flight to Houston on Sunday night when the news broke. Their veteran right-hander was headed to the wild-card-leading Chicago Cubs.

News of the deal first surfaced through Ken Rosenthal of The Athletic. Gausman would only make a brief pit stop in Texas before continuing on to Chicago. Meanwhile, the Jays confirmed the trade just a few hours later.

In return, Toronto received two well-regarded farmhands: shortstop Ty Southisene and outfielder Brett Bateman. According to MLB Pipeline, they rank as the Cubs’ 13th- and 21st-best prospects. As a result, the Jays add fresh, controllable talent to their farm system.

Gausman’s Legacy With the Blue Jays

Gausman, 35, leaves behind a resume few Toronto pitchers can match. He started on opening day this season, and he also took the mound for Game 1 of last year’s post-season. Additionally, he opened the American League Championship Series against Seattle and started Games 2 and 6 of the World Series. He even picked up the win in relief during Game 7 of the ALCS.

The beloved right-hander signed a five-year, $110-million contract ahead of the 2022 season. Since then, he has arguably become the franchise’s greatest free-agent pitching signing. For context, Roger Clemens won two Cy Youngs in Toronto, but he only pitched there for two seasons.

Beyond the accolades, Gausman built a genuine connection with the city. He became a Cy Young finalist, earned an all-star selection, and posted a microscopic 0.99 WHIP across three post-season runs. Furthermore, he has often called signing with the Jays the best decision of his career.

“I hope (the fans) realize that I’ve embraced not just the team but the country, really love this city and everything it stands for,” Gausman said. He shared those words after his fifth win of the season in a 5-1 victory over the St. Louis Cardinals on Saturday. Notably, that outing marked his 77th and final home start at the Rogers Centre.

Off the field, Gausman has often spoken about raising his daughters, seven-year-old Sadie and four-year-old Sutton, in Toronto. The family enjoyed biking around Evergreen Brick Works and browsing Summerhill Market. They also spent plenty of time hunting down the city’s best cinnamon bun. On top of that, Gausman was the only Jays starter to avoid missing a turn in the rotation this season.

What the Blue Jays Are Getting in Return

So, what does Toronto gain from the Gausman Cubs trade? Southisene stands out as a light-hitting shortstop with terrific speed and a reliable glove. Consequently, he profiles as a classic table-setter rather than a power bat.

The Las Vegas native was Chicago’s fourth-round pick back in 2025. Since an early-May promotion to High-A South Bend, he has hit .326 with a stellar .451 on-base percentage across 44 games. In other words, his plate discipline already looks advanced for his age.

Southisene has also stolen 72 bases while getting caught just 14 times across two pro seasons. However, he has yet to hit a home run, and scouts currently grade his power at only 20 on the 20-80 scale. Even so, his speed and contact skills give him a realistic path to the majors.

A Sell-Off Begins in Toronto

This trade signals the start of a broader shift for the Blue Jays’ front office. With Gausman’s departure, the team clearly prioritizes long-term roster flexibility over an immediate playoff push. Meanwhile, fans across Toronto are left processing the exit of one of the franchise’s most popular modern players.

Ultimately, the Kevin Gausman Cubs trade closes one chapter while opening another for both franchises. Chicago adds a proven post-season arm to bolster its wild-card push. Toronto, on the other hand, restocks its farm system with two prospects who could contribute in the years ahead.
