At Bucknell University in Lewisburg, Pennsylvania, he played three seasons from 2022 to 2024 and slashed .358/.476/.711 in 110 combined games with 38 doubles, four triples, 27 home runs, 124 RBI, and a 1.187 OPS.[4](https://www.mlb.com/player/sean-keys-815873) As a sophomore he earned First-Team All-[Patriot League](https://www.edgepedia.org/patriot-league) honors, and as a junior in 2024 he was awarded the Patriot League Player of the Year after slashing .405/.535/.798 with 13 home runs and more walks than strikeouts for the first time in his career.[4](https://www.mlb.com/player/sean-keys-815873) • [5](https://www.baseballamerica.com/players/1499903-sean-keys/) He graduated as a mechanical engineer, with one of his projects being a robot that could follow a taped line on the floor.[4](https://www.mlb.com/player/sean-keys-815873)
In collegiate summer play he appeared with the Westhampton Aviators and the Cotuit Kettleers of the Cape Cod League, combining to slash .327/.422/.618 with 20 home runs and a 1.039 OPS in 72 contests.[4](https://www.mlb.com/player/sean-keys-815873) [Baseball America](https://www.edgepedia.org/baseball-america)'s draft report noted that Bucknell had produced only one previous player who was drafted and reached the major leagues, right-hander Eric Junge, and that Keys was expected to become the third Bucknell player selected among the top 10 rounds.[6](https://baseballsavant.mlb.com/savant-player/sean-keys-815873)
## Professional career
The Blue Jays selected Keys in the fourth round (125th overall) of the 2024 draft and signed him for $569,700, close to slot value.[2](https://www.baseball-almanac.com/players/college.php?p=keysse01) • [6](https://baseballsavant.mlb.com/savant-player/sean-keys-815873) He began his professional career with Class-A Dunedin in August 2024, slashing .293/.378/.451 with an .829 OPS in 22 games.[4](https://www.mlb.com/player/sean-keys-815873)
**2025: Vancouver.** Keys spent the entire 2025 season at High-A with the [Vancouver Canadians](https://www.edgepedia.org/vancouver-canadians), hitting .217/.365/.408 with 19 home runs in 119 games. His 16.3% walk rate ranked second among qualified hitters in the Northwest League, and he was named NWL Player of the Week on September 7, 2025.[4](https://www.mlb.com/player/sean-keys-815873) The 19 home runs set both the [Canadians](https://www.edgepedia.org/canadians)' single-season and franchise all-time records.[3](https://www.mlb.com/milb/new-hampshire/news/sean-keys-debut)
**2026: rise to the majors.** Keys began 2026 with the Double-A New Hampshire Fisher Cats, where in 49 games he slashed .285/.411/.581 with 23 extra-base hits and took Eastern League Player of the Week honors on April 20.[3](https://www.mlb.com/milb/new-hampshire/news/sean-keys-debut) Promoted to Triple-A Buffalo on June 5, he had 21 home runs between the two levels by late June and was described as the Blue Jays' No. 14 prospect.[7](https://www.mlb.com/news/sean-keys-blue-jays-prospect-pushing-for-promotion) Toronto selected his contract on June 27, 2026, and he debuted that day as the starting first baseman, batting sixth and going 1-for-4 with a single in a 7-4 loss to the Texas Rangers at [Rogers Centre](https://www.edgepedia.org/rogers-centre).[3](https://www.mlb.com/milb/new-hampshire/news/sean-keys-debut) • [8](https://www.mlb.com/news/sean-keys-gets-called-up-to-majors-by-blue-jays)
After a 12-game stretch in which he went 6-for-36, the Blue Jays optioned him to Buffalo on July 23, 2026, and recalled him on September 1 as a September reinforcement.[9](https://www.milb.com/player/sean-keys-815873) He finished the 2026 major league season with 12 hits, 2 home runs, 9 RBI, and a .197 average in 61 at-bats, playing 12 games at first base, one at third base, and two in left field.[1](https://www.baseball-reference.com/players/k/keysse01.shtml) • [4](https://www.mlb.com/player/sean-keys-815873) His minor league production earned him recognition after the season: Baseball America named him the Blue Jays' Minor League Player of the Year, and MLB Pipeline named him a Blue Jays Prospects of the Year with 28 home runs and a 1.019 OPS.[5](https://www.baseballamerica.com/players/1499903-sean-keys/)
## Scouting report
MLB's 2026 scouting grades rate Keys at Hit 45, Power 55, Run 40, Arm 55, Field 45, and Overall 45 on the traditional 20-to-80 scale, describing him as a rare case of a prospect profile leaning heavily on the slug in a system otherwise filled with "solid across the board" position players.[6](https://baseballsavant.mlb.com/savant-player/sean-keys-815873) His power is described as coming easy, produced without a max-effort swing, and he rarely swings and misses or chases pitches, with a particular ability to punish fastballs.[6](https://baseballsavant.mlb.com/savant-player/sean-keys-815873)
Defensively, Keys was a third baseman throughout his college career, but evaluators question whether his range and quickness allow him to stay at the position; he made 11 errors there in 2024, and a move to first base is considered the most likely outcome.[6](https://baseballsavant.mlb.com/savant-player/sean-keys-815873) Baseball America's post-draft report credits him with an above-average arm and exceptional hard contact from an uphill bat path geared for over-the-fence power, while noting that his 2025 stat line at Vancouver understated his underlying contact and approach.[5](https://www.baseballamerica.com/players/1499903-sean-keys/)
