4:15pm: Bolton is dealing with kidney stones, per Ryan Divish of The Seattle Times.
3:10pm: The Mariners shook up their bullpen with a series of roster moves Monday. Right-handers Brett de Geus and Tyson Miller were selected to the 40-man roster from Triple-A Tacoma, with righty Ty Adcock being designated for assignment to open a spot on the 40-man roster. Right-handers Cody Bolton and Collin Snider were both placed on the 15-day injured list — the latter due to a knee contusion and the former with what the team labeled a “general medical issue.” The Mariners also reinstated first baseman Ty France from the paternity list and optioned infielder/outfielder Samad Taylor to Tacoma.
Both Miller and de Geus have big league experience, albeit fairly minimal. The 28-year-old Miller was a fourth-round pick by the Cubs back in 2016 and has pitched for five different teams over the past four years (Cubs, Rangers, Mets, Dodgers, Brewers). In 31 career innings, he’s been tagged for an ugly 6.97 ERA, though his Triple-A work is far better. Miller was roughed up for an ERA north of 7.00 in his first taste of Triple-A as a 23-year-old back in 2019. In parts of three seasons since that time he’s logged a 3.85 ERA in just under 200 innings. That includes 43 2/3 innings of 3.50 ERA ball with the Triple-A clubs for the Dodgers and Mets last year, during which he punched out 28% of his opponents.
The 26-year-old de Geus pitched 50 MLB frames between the Mariners and D-backs back in 2021 after Texas plucked him from the Dodgers in the 2020 Rule 5 Draft. He made 19 appearances as a Rangers and another 26 as a D-back, struggling mightily in both stops. Given that de Geus pitched in A-ball in 2019 then didn’t pitch with an affiliate in 2020 due to the canceled minor league season, it’s not all that surprising that he was hammered by MLB hitters in his debut campaign. In those 50 frames, he yielded a 7.56 ERA.
Even to this point in his career, de Geus only has 14 Triple-A frames under his belt. He’s been hit hard in that tiny sample as well, but he pitched 35 1/3 innings with a 2.80 ERA in Double-A for the Royals last season. De Geus has plenty of experience working multiple innings as a reliever and has also been a starter in the past, so he can provide some length to the Seattle bullpen while he’s up.
Adcock, 27, made his big league debut with the Mariners in 2023. The former eighth-round pick tossed 15 2/3 innings with a 3.45 ERA and 19% strikeout rate out of Scott Servais’ bullpen and didn’t issue a walk or hit any of his 58 opponents with a pitch. Adcock was never going to sustain that level of command, but he still walked only five of the 75 hitters he faced between High-A and Double-A last year (6.66%). However, he’s already issued three free passes in 2024 despite facing just a dozen opponents. The Mariners will have a week to trade Adcock, attempt to pass him through outright waivers or release him.
