LAS VEGAS — The annual General Managers Meetings mostly are about laying the groundwork for moves that might happen later in the offseason, but the Giants made a minor trade Tuesday on the first full day of the event in Las Vegas.

San Francisco acquired right-handed pitching prospect Logan Martin from the Kansas City Royals in exchange for right-hander Mason Black , who had been designated for assignment last week after a couple of waiver claims. Black will get an opportunity to try and contribute in the American League, while the Giants get a 24-year-old who does not have to take up a spot on their 40-man roster and potentially can help down the line.
"We had to make a decision on Mason and we're fortunate to get an arm-strength starter back in the system," general manager Zack Minasian said Tuesday morning.
Martin, a 12th-rounder out of Kentucky in 2023, pitched in High-A last season, posting a 3.45 ERA across 22 starts. He has a 3.49 ERA in three minor-league seasons, although his strikeout rate has dipped in Single-A. Martin, who relies primarily on a mid-90s four-seamer and a cutter, currently is pitching in the Arizona Fall League.
The Giants have tried to add young pitching in every deal over the past year and plan to be aggressive in adding depth at all levels this offseason. At the same time as they DFA'd Black, who struggled in his big-league stints, they acquired lefty reliever Reiver Sanmartin from the Cincinnati Reds and outfielder Justin Dean from the Los Angeles Dodgers .

Those two waiver claims were the first for the organization since before the 2025 season. Minasian said the front office liked Sanmartin's versatility and noted he has big-league experience. Dean joins a crowded outfield group on the 40-man roster, but the Giants consider him to be the best defender of the group and the fastest baserunner. Minasian said adding a lefty relief option and potential bench outfielder "felt like two things that fit the roster at this time."
"We're happy to have him on," he said of Dean, who appeared in the World Series with the Dodgers. "We'll see what he can do in Arizona (next spring)."
