If the Seattle Mariners wind up moving a starting pitcher before the Aug. 3 trade deadline, the obvious name is Luis Castillo. But the more interesting possibility right now is Emerson Hancock.
According to people briefed on the Mariners’ talks, Seattle is telling teams it is open to dealing Hancock as it looks for a right-handed bat. Castillo, 33, carries the heavier contract burden: he is owed the rest of $22.75 million this season and another $22.75 million in the final guaranteed year of his deal next season. With the pending lockout threatening to cut into the 2027 season, that extra expensive year could make him a tougher fit for trade partners.
Hancock is a different kind of asset. He is making $793,300 this season and remains under club control for four more seasons through 2030.
He has also put together a breakout year, though his expected ERA in 19 starts is more than a run per nine innings higher than his actual 3.16. Teams may not see him as a true front-line starter, but a quality major league arm with that kind of control still carries real value.
Seattle is in a position to listen because it has six healthy starters right now. Behind that group, the organization also has two highly regarded Double A arms in left-hander Kade Anderson and righty Ryan Sloan, along with righty Logan Evans, who is expected back from Tommy John surgery next season.
Hancock opened the year in the rotation after Bryce Miller went down, but he is not viewed in the same tier as Logan Gilbert, George Kirby and Bryan Woo, all of whom the Mariners are unlikely to discuss, sources said. Miller, who is pitching better than he has at any point in his career and is under club control for three more seasons, is also in that near-off-limits category.
The Mariners’ goal is clear: add offense and rebalance the roster. In a deadline market where fewer sellers are eager to move prospects, major league-for-major league deals look like the most realistic path. Hancock could be part of one.
The Chicago Cubs fit as a possible match. They have already added left-hander David Peterson and righty Aaron Civale while trying to stabilize their rotation, and Hancock would make sense as another starter to pursue. Seattle, meanwhile, could have interest in one of the Cubs’ right-handed bats, with right fielder Seiya Suzuki, infielder/outfielder Matt Shaw and outfielder Kevin Alcántara all potential fits.
Chicago is also looking across the market, though, and could connect with the Los Angeles Angels on righty José Soriano or lefty Reid Detmers.
The Angels, according to a person briefed on their pursuits, want to land a young catcher. Owen Ayers, the Cubs’ No. 10 prospect according to The Athletic’s Keith Law, could fit that description. Ayers is 25 and has moved from High A to Triple A this season.
Soriano, 27, and Detmers, also 27, are each under control for two more seasons, but neither comes without questions. Soriano opened with a 0.84 ERA through seven starts, then posted a 4.90 mark over his next 14, though he has been better recently. He has also had two Tommy John surgeries, in February 2020 and June 2021.
Detmers has reached 120 innings, nearly twice last year’s total when the Angels used him only as a reliever. He logged 148 2/3 innings in the majors in 2023 and 165 1/3 between the majors and minors in ’24, but some teams worry he could wear down over the final two months and into the postseason.
The Tampa Bay Rays are being watched closely because two Florida government bodies are set to vote in August on the club’s proposed $2.3 billion ballpark. That naturally invites speculation about whether the Rays might push harder at the deadline to help their case with the Hillsborough County Commission and Tampa City Council, both of which approved a non-binding Memorandum of Understanding in May.
The answer, though, is no. The Rays do appear ready to “buy big” if the right players become available, but their financial situation has not changed.
Public financing remains uncertain, and the club’s commitment of more than $1.2 billion is still on the table. So Tampa Bay is expected to operate the way it usually does: aggressively, but with limited payroll room.
The Padres are in a similar holding pattern while awaiting league approval of their $3.9 billion sale to a group led by José E. Feliciano and Kwanza Jones. People familiar with the team’s thinking say Feliciano and Jones have been in contact with Padres executives, which could create some extra payroll flexibility if San Diego decides to buy at the deadline, though how much remains unclear.
The White Sox are also trying to solve a problem behind the plate after losing Kyle Teel for 8 to 12 weeks with a high left ankle sprain. Teel told MLB.com he thinks the absence could be closer to five to eight weeks, but either way Chicago is “working hard” to add a catcher, according to a person briefed on the plan. The White Sox would like an upgrade over Edgar Quero and Drew Romo, though the market is thin and the Rays, Yankees and Dodgers are also in the hunt for catching help.
Two names drawing attention are Cincinnati’s Tyler Stephenson and Minnesota’s Ryan Jeffers. Stephenson and Jeffers are both 29 and both could reach free agency.
Jeffers has been the better hitter this season, posting a .950 OPS, while Stephenson sits at .712. Jeffers returned July 10 after missing nearly two months with a left hamate bone fracture and went 5-for-21 in his first six games back, but he also hit two homers, two doubles and drew three walks.
Stephenson, meanwhile, has rebounded after a rough first two months and entered Thursday with a .928 OPS over his previous 27 games.
Even if Stephenson is not quite Jeffers offensively, he would still be a clear upgrade for the Yankees, whose catching group ranks next-to-last in the majors in wRC+, ahead of only the White Sox.
And one more team to keep an eye on: the Rangers. Texas opens a four-game home series against the Mariners on Friday night in a matchup that could say plenty about where the club is headed. The Rangers are 2-4 since the break after losing a series in Atlanta and another at home against the White Sox, and they sit right on the edge at .500 with playoff odds entering Thursday at 50 percent.

White Sox Prospect Rankings Just Took An Unexpected Turn
MLB Pipelines latest White Sox top-30 prospect update brought a few familiar names into sharper focus, but the most notable shift was Boston Smith cracking the list at No. 15 after entering unranked before. The refreshed rankings also reflect how much the system has changed in recent weeks, with Braden Montgomery, Noah Schultz and Sam Antonacci all having moved on to new levels, leaving the organizations prospect picture in a different place than it was not long ago.
The list is still a little unfinished, though, because it does not yet account for the White Soxs 2026 draft class while the signing deadline remains ahead. That means Caleb Bonemer is sitting atop the board for now, even as the next wave of talent looms, and he also had another rough moment in Birmingham when he was hit in the helmet again after striking out and had to be replaced.

White Sox Top Prospect Sparks Concern After Frightening Exit
Fridays minor league slate was a mixed bag for the White Sox system, which split its six games while a few bats kept the day from becoming a total wash. Korey Lee, Jason Matthews, Boston Smith and Anthony DePino all went deep for their affiliates, giving the organization some offense to point to on a day when several of the headlines were scattered across the farm.
The most jarring moment came when Caleb Bonemer was hit in the head by a pitch and left the game, a frightening scene for one of the clubs top prospects. Preliminary tests were encouraging, but he remains under evaluation, leaving the White Sox with a familiar minor league concern: the results on the scoreboard matter less than the health update that follows.

White Sox Could Finally Make A Future Shaping Deadline Swing
The White Sox are heading toward the trade deadline with a different kind of urgency than the one that usually comes with a rebuilding club. Rather than shopping only for short-term fixes, they are reportedly open to making a more aggressive move for players who come with contract control, the kind of deal that could matter well beyond this season. That approach fits a team still trying to shape its next competitive core, and it gives the front office a chance to chase upside instead of simply filling holes.
There are a few paths they could explore, including arms from the Angels and a potential impact bat from the Athletics, but the challenge is obvious: controllable talent rarely comes cheap. Even when a player looks attainable, the price tag and the odds of a deal actually getting done can be very different things. For a White Sox club trying to balance patience with progress, this deadline could be the first real test of how bold it wants to be. [Read more 🡒]
