Here are the Mariners' Draft picks from Day 2

SEATTLE -- The Mariners have built themselves a reputation as one of the better organizations in baseball at identifying, developing and maximizing pitchers, and that reputation was reinforced even further as the club wrapped up another pitcher-heavy Draft.

“It’s a real competitive advantage for us right now because of the track record of what our guys have done, and the culture that has built here around pitching,” Mariners vice president of amateur scouting Scott Hunter said.

Seattle made the most of that advantage Monday, taking 11 arms in the final 17 rounds. And the arms they chose filled a whole lot of profiles -- nine right-handers and two southpaws, multiple guys coming off Tommy John, plenty of relievers and arm angles at “different areas of the clock,” in Hunter’s words.

“We have kind of a mantra around here, as soon as we get to the [second] day or the later rounds. It’s like, give us somebody who’s really performed, really pops on some sort of analytics or someone who has a plus in a box,” Hunter said. “Just over time, the more of those guys we take, we seem to be able to develop into real Major League value or trade value.”

The Mariners also took their first outfielder of the Draft in the fifth round -- the highest they’ve picked a college outfielder since Zach DeLoach in 2020. Beyond that, they went heavy on catchers -- drafting two more backstops to go along with second-round pick Luke Stevenson.

Mason Peters, P
Round: Fourth (No. 122 overall)
Bats/throws: L/L
School: Dallas Baptist University
Calling card: The second southpaw taken by the Mariners this Draft, Peters -- who began his collegiate career at Temple College (Texas) -- is coming off a season at DBU that earned him second-team All-Conference USA honors, logging four saves and a 4.25 ERA with 58 strikeouts in 42 1/3 innings. Coming in at 5-foot-11, Peters has a fastball that sits in the mid-90s, paired with a curveball that can miss plenty of bats.
Quote: “Mason Peters is probably one of the more exciting guys in our Draft this year. … Unreal spin rates on his breaking ball. Our scouts really love the way he moves. It was one of those picks that kind of connected every dot along the way.” -- Hunter

Korbyn Dickerson, OF
Round: Fifth (No. 152 overall)
Bats/throws: R/R
School: Indiana University
Calling card: Dickerson was a top-250 prospect as a high school senior in 2022 but chose to go to Louisville after being drafted by the Twins in the 20th round. After two quiet years at Louisville, he transferred to Indiana, where he racked up 19 home runs and 77 RBIs as a redshirt sophomore, rising up MLB Pipeline’s Draft prospects rankings to No. 83. Dickerson brings some of the best bat speed and exit velocities in the college ranks, along with a 60-grade speed tool and above-average fielding in center field. There are a few questions about his track record against high-level pitching, but if he can hammer down his approach, he has the tools to do damage in multiple ways.
Quote: “We actually thought Korbyn was going to go a lot higher in this year’s Draft. When he started to slip a little bit, our guys kept saying, ‘He’s a tools player, can really run, he’s got real power.’ … He only really has one year of college baseball under his belt. Obviously there are some holes to his game that we think we can help. But the underlying foundation of his power, speed and size, we think he can run around center field, if not play all three.” -- Hunter

Lucas Kelly, P
Round: Sixth (No. 182 overall)
Bats/throws: R/R
School: Arizona State
Calling card: Kelly spent his lone season in Tempe as a full-time reliever, striking out 34 batters in 26 2/3 innings for the Sun Devils. His primary weapon is a fastball that’s gotten up to 99 mph out of a low armslot that gives him a ton of run to work with, and that slot amplifies the movement on his breaking ball.

Colton Shaw, P
Round: Seventh (No. 212 overall)
Bats/throws: R/R
School: Yale University
Calling card: Seattle’s first starting pitcher pick on Day 2, Shaw ate innings for the Bulldogs his entire four-year collegiate career, logging a 3.13 ERA and a .221 opponents' average in 77 2/3 innings with 80 strikeouts as a senior. He ended the season with a string of five starts that all went at least 7 1/3 innings -- including one nine-inning outing -- in which he allowed just four runs. Shaw brings a standard right-hander’s three-pitch arsenal, matching a mid-90s sinker with a slider and a changeup.
Quote: “Shaw actually turned down two or three other organizations, and there was a funny moment when [his] agent thought he was turning down another organization, and it was us, and the kid called right away and said, ‘No, I want to be with the Mariners, I don’t want to be with those other teams.’” -- Hunter

Danny Macchiarola, P
Round: Eighth (No. 242 overall)
Bats/throws: L/R
School: Holy Cross
Calling card: The Mariners will need to convince Macchiarola to sign instead of transferring to Miami, where he committed July 2. The right-hander earned second-team All-Patriot League honors as a sophomore in 2024 and as a junior again this past season, racking up a 3.27 ERA with 92 strikeouts in 93 2/3 innings with a sinker/slider/changeup mix.

Jackson Steensma, P
Round: Ninth (No. 272 overall)
Bats/throws: S/R
School: Appalachian State
Calling card: Steensma didn’t pitch in 2025 after undergoing Tommy John surgery in December, but fits a common mold for what the Mariners like in college pitchers, and Hunter said he will probably be ready for Spring Training in 2026.. The right-hander stands 6-foot-4 and combines good extension with a shorter pitch-release height, with a low-to-mid-90s fastball that’s topped out at 96 mph, paired with a tight slider and a changeup. He began his collegiate career as App State’s closer, racking up seven saves as a freshman, before logging a 4.03 ERA in 14 starts in ‘24.
Quote: "I’m not saying he’s going to be Bryan Woo, but our PD guys have done a lot of good things with guys in the later rounds that are coming off injuries. He’s a power arm, he’s a big body, he’s a horse of a human being who can eat innings. But when he’s healthy, he’s also up to 96. Our scouts really liked what they saw prior to the injury, but our analytics team said there were some things that made it worth a shot.” – Hunter

Isaac Lyon, P
Round: 10th (No. 302 overall)
Bats/throws: R/R
School: Grand Canyon
Calling card: The son of 12-year MLB veteran Brandon Lyon, the right-hander racked up 88 strikeouts in 86 innings as Grand Canyon’s Friday starter, posted a 4.19 ERA, and finished his career with the Lopes with a BB/9 just a shade over 2. Last summer, he struck out 10 in 8 1/3 innings in the Cape Cod League, making three of his four appearances out of the bullpen. He’s got a low arm slot, giving him good movement on his fastballs, and also has a sweeper and a high-use changeup.

Dusty Revis, P
Round: 11th (No. 332 overall)
Bats/throws: R/R
School: Western Carolina
Calling card: Revis posted a 4.04 ERA in 15 starts at Western Carolina, where he was teammates with Cal Raleigh’s cousin, Brody. The 6-foot-2 right-hander has experience pitching both as a starter and in relief -- 17 of his 19 appearances in ‘24 came out of the bullpen -- and improved his fastball velocity into the consistent mid-90s this past year. Before playing at WCU, he began his career at Mars Hill University (N.C.) but suffered a season-ending stress fracture in his second year.

Grant Jay, C
Round: 12th (No. 362 overall)
Bats/throws: R/R
School: Dallas Baptist
Calling card: Peters’ catcher at DBU -- and the second backstop to be picked by Seattle this Draft -- Jay was a an ABCA first-team All-American and earned first-team all-conference USA honors as a junior. Jay’s main tool is his power -- he hit a program-record 61 home runs in just three years, teeing off for 21 homers in ‘23 and ‘24, and 19 in ‘25, to boast a career 1.116 OPS. But his average has stayed above .300 all three seasons, and threw out 11 of 43 would-be base-stealers behind the plate this season -- though Hunter said he could also get looks at other positions.

Aiden Taurek, OF
Round: 13th (No. 392 overall)
Bats/throws: R/R
School: Saint Mary’s College
Calling card: Taurek began his collegiate career as a pitcher and third baseman at Foothill College (Calf.) but moved to the outfield after making the jump to Division I, starting 61 of the Gaels’ 62 games this season in left field. He hit .328 with 33 extra-base hits and a .980 OPS.

Luke Heyman, C
Round: 14th (No. 422 overall)
Bats/throws: R/R
School: University of Florida
Calling card: A first-team all-SEC catcher and semifinalist for the Buster Posey Award, Heyman joins Luke Stevenson and Jay as power-first catchers in the Mariners’ haul. He posted a .975 OPS as a junior for the Gators with 13 homers and 44 RBIs in 49 games, though he suffered a season-ending forearm fracture in May when he was hit by a pitch. That could delay the beginning of his development in Seattle’s system -- should he choose to sign instead of returning to Gainesville for his senior season.
Quote: “He can come in, and we think he’s got a lot of real, raw power.” -- Hunter

Brayden Corn, OF
Round: 15th (No. 452 overall)
Bats/throws: R/R
School: Western Carolina
Calling card: Seattle circled back to WCU for a second Catamount, taking Corn, who started 57 games in center field this past season. He compiled a .312 average with 13 doubles and 11 home runs, and also stole 19 bases. Corn ended his season on a heater, going 7-for-13 with three homers, a double, six RBIs and a walk in the SoCon Tournament to make the all-Tournament team.

Casey Hintz, P
Round: 16th (No. 482 overall)
Bats/throws: R/R
School: University of Arizona
Calling card: Hintz threw a career-high 55 innings in his junior season, and through three seasons in Tucson has a career 5.17 ERA. He raised his strikeout rate up to nearly a K per inning this past year, with a lower arm slot that gives extra movement to his sinker, which in turn sets up a frisbee slider and a changeup.
Quote: “A different-look guy. Guys were in the room working through some of his pitch action, and some of our scouts and analysts were sitting in front of the computer watching how much movement he has on his cutter. That kind of stuff jumps out at us, because our guys in PD love action to their stuff.” -- Hunter

Anthony Karoly, P
Round: 17th (No. 512 overall)
Bats/throws: R/R
School: Nova Southeastern University (Fla.)
Calling card: Karoly missed all of 2024 with an injury, but came back this season, allowing a .167 opponents' average in 28 innings and striking out 47 of the 116 batters he faced -- though he did also walk 18. By the end of the spring he was starting to get stretched out, lengthening out to five innings, but he didn’t appear for Nova Southeastern in the final two weeks of the season.
Quote: “He’s a guy that has some interesting action shapes his breaking ball.” -- Hunter

Griffin Stieg, P
Round: 18th (No. 542 overall)
Bats/throws: R/R
School: Virginia Tech
Calling card: Stieg, who missed the ‘25 season recovering from Tommy John surgery, is currently committed to transfer to Alabama next season, and it sounds like it might be an uphill battle to get him to sign. In ‘24, he posted 48 strikeouts and just 13 walks in 51 1/3 innings, logging a 4.70 ERA.
Quote: “We did try to sign Stieg earlier in the Draft, but he had some NIL money from his college and we didn’t want to go too far. But if we do have some extra at the end of this thing, we may make a run at him.“ -- Hunter

Cameron Appenzeller, P
Round: 19th (No. 572 overall)
Bats/throws: L/L
School: Glenwood H.S. (Ill.)
Calling card: Appenzeller, a 6-foot-6 18-year-old, is listed as MLB Pipeline’s No. 58 Draft prospect, but has already told reporters that he plans to honor his commitment to play college ball at Tennessee next year.

Estevan Moreno, SS
Round: 20th (No. 602 overall)
Bats/throws: R/R
School: Notre Dame
Calling card: Moreno slashed .230/.339/.485 as a junior for the Fighting Irish, logging 14 doubles, 10 home runs and 43 RBIs, but struck out 72 times in 53 games. Seattle scouts were more intrigued by his arm at shortstop, even floating the possibility of a move to the mound.
Quote: “His defensive potential and his arm strength … Guys said that if he doesn’t work out at the plate, he could be a pitcher some day." -- Hunter
