Toronto Blue Jays Promote Top Prospect Sean Keys to Major League Roster

The Toronto Blue Jays announced the promotion of 23‑year‑old infielder Sean Keys, their No. 14 prospect, to the major‑league roster. Keys, a 2024 fourth‑round draft pick, has logged 21 home runs between Double‑A New Hampshire and Triple‑A Buffalo this season, posting a .284/.409/.619 slash line and a 164 wRC+. The club will need to make concurrent moves to add him to the 40‑man and active rosters, with the call‑up expected to become official on Saturday.

The promotion comes as Toronto struggles for power; the lineup is near the bottom of the American League in home runs, and star first baseman Vladimir Guerrero Jr. has only four homers this year. Blue Jays manager John Schneider said the team is exploring defensive options for Keys, who has played only first and third base in the minors and may see time in corner outfield. The added bat is seen as a potential boost in the tight Wild‑Card race, where the Jays sit around .249/.311/.391 with a 39‑42 record.

Keys' minor‑league performance includes a recent multi‑homer game for the Buffalo Bisons, where he hit two long balls (426 ft and 395 ft) in an 18‑11 loss. Over 66 games across Double‑A and Triple‑A, he has compiled a .286 average, .411 on‑base percentage and a 1.026 OPS, with 20 home runs and 52 RBIs.
