The Seattle Mariners may end up holding one of the biggest cards on the market before Monday’s Major League Baseball trade deadline, and George Kirby is suddenly the name drawing the loudest buzz.
According to ESPN’s Kiley McDaniel and Jeff Passan, the right-hander’s chances of being dealt have climbed fast over the past several days. They put the odds at 50%, and they framed the possibility as something that could reshape the deadline landscape.
"Seattle's openness to moving Kirby could be a deadline game changer, with the starting pitching market at a standstill and Kirby rising to the top of all non-Skubal arms," McDaniel and Passan wrote.
They also made clear why so many teams would line up if Kirby becomes available.
"With a fastball that sits at 97 mph, arguably the best command of any starter in baseball and two years of club control beyond this season, Kirby is a prize for contenders and noncontenders alike. If he moves, the return will be hefty," they added.
Kirby, a 2023 All-Star, has posted a 3.76 ERA this season while allowing an American League-high 136 hits in 127 innings over 21 starts. Even with that hit total, his control remains his calling card. He owns a career walk percentage of 3.8%, a number that helps explain why he’s viewed as one of the most polished starters in the game.
For teams scrambling to upgrade their rotations, the timing could be everything. The Mariners are expected to hear plenty of calls before the 6 p.m.
EDT deadline, and Kirby’s contract situation only adds to the intrigue. The 28-year-old won’t reach free agency until 2029.
Among the clubs that could be especially aggressive are the Chicago Cubs and Atlanta Braves, two National League teams in clear need of starting pitching help. Kirby would slide into either rotation without much fuss if Seattle decides to make the move.

Cubs Just Got Pulled Into Torontos Deadline Rotation Shakeup
Torontos deadline-day rotation shuffle has already sent ripple effects through the league, and the Cubs were pulled into the middle of it before the dust could settle. The Blue Jays moved quickly ahead of the Aug. 3 deadline, adding Jose Soriano from the Angels while also reshaping the staff with veteran arms, a sign they were prioritizing immediate stability as they mapped out the rest of 2026 and even looked ahead to 2027.
For Chicago, the bigger story is how this kind of deal changes the market around it. A club in deadline mode can turn one trade into a broader reset, and the Cubs now sit in the orbit of a Blue Jays rotation plan that could still keep evolving as Toronto weighs future moves involving its veteran pitchers. Even after the first wave of action, the way Toronto sorts out its staff may decide whether this becomes a one-off adjustment or the start of something bigger. [Read more 🡒]
Cubs Just Paid A Real Prospect Price For An October Push
The Cubs made a clear win-now move, parting with one of their better infield prospects to shore up the roster for the stretch run. Jefferson Rojas was sent to the Mets in a deal that brought back Clay Holmes and Tyrone Taylor, a transaction that signals Chicago is treating October as more than a distant goal and more like a window worth pushing through right now.
Holmes gives the Cubs a right-handed arm who is still on the injured list but getting close to a return, while Taylor adds experienced outfield depth for the final months of the season. It is the kind of trade that usually comes with an uncomfortable cost, and Chicago paid it by moving a player it had reason to value, betting the short-term upgrade will matter more than the long-term regret.

Cubs Just Got A Surprising Deadline Opening They Still Needed
The Cubs still have not made a trade move, but they do have one of the more intriguing deadline paths to monitor as they poke around with Texas. The Rangers have shifted their approach enough to at least listen on some pitching, which has put Chicago in the mix for arms such as Nathan Eovaldi, MacKenzie Gore and Jacob Latz. For a club looking for help without blowing up its deadline, that kind of opening is worth watching closely.
Texas, though, has also sent a mixed message to rival front offices, which is part of what makes this whole thing feel so unsettled. Trade talks can turn quickly at this time of year, and the Cubs are weighing options in a market where the other side may not be nearly as available as it first seemed. [Read more 🡒]
