A host of good MLB starting pitchers are "potentially available" via trade, per Mark Feinsand of MLB.com.

"According to sources, those pitchers potentially available include Seattle's Luis Castillo, Miami's Jesús Luzardo, San Diego's Dylan Cease, Houston's Framber Valdez and St. Louis' Sonny Gray," Feinsand wrote. "Of that group, Gray is the only one with a full no-trade clause in his contract."

Of course, that's in addition to solid arms already available via free agency, including Corbin Burnes, Max Fried and Jack Flaherty.

Feinsand broke down the contract situations for all four pitchers mentioned.

"Castillo is signed for $68.25 million over the next three years, with a vesting option for 2028 if he throws 180 innings during the 2027 season. The Mariners are loaded with starting pitching and need a bat, making Castillo a logical contract to move to acquire an impact hitter.

"Gray is set to make $25 million in 2025 and $35 million in 2026, with a $30 million club option for 2026.

"Cease and Valdez are arbitration-eligible for the final time this winter, set to become free agents next offseason. Like Crochet, Luzardo is under club control for two more years before becoming a free agent."

Castillo was brought into Seattle after a 2022 midseason trade from the Cincinnati Reds, and he immediately helped the Mariners make the playoffs for the first time since 2001. In September of the 2022 season, Castillo signed a five-year, $108 million extension to remain with the team.

But it appears Seattle, whose faltering offense torpedoed the team's postseason hopes last year, could be going in a different direction now with the M's in need of hitting.

Gray fared well in his first year for the St. Louis Cardinals after landing in town following an American League Cy Young runner-up season with the Minnesota Twins in 2023, going 13-9 with a 3.84 ERA and 109 ERA+.

But St. Louis tried to vault itself into the World Series with Paul Goldschmidt (a free agent) and Nolan Arenado leading the way. That didn't happen, and perhaps now is the time to look forward to a new era.

The situations with Cease and Valdez could very well be ones where the San Diego Padres and Houston Astros, respectively, want to see what they get on the trade market to avoid losing those pitchers for nothing in free agency. The Boston Red Sox appear to have interest in Cease, per Jon Morosi of MLB Network.

As for Luzardo, the Miami Marlins, as has been the case for seemingly forever, are in rebuilding mode. So they too could be looking to deal Luzardo in hopes of building up the farm system.

In essence, it wouldn't be a big surprise if some of these names move. Fans are already expecting the likes of Burnes and Fried to find new homes in free agency, but they could be flanked by others in the trade market as well.
