Why Spencer Miles fits the Blue Jays' 2027 rotation picture

By Vanessa Serrao | Last updated Jul 2, 2026 4:32 PM ET

Rule 5 draft pick Spencer Miles has continued to prove that he's a vital part of the Toronto Blue Jays' success. His reliability on the mound this season has painted a clear picture that he should be a part of the Blue Jays' rotation plans in 2027.

On the season, he has logged an impressive 4-1 record with a 2.83 ERA with 55 strikeouts and a 1.04 WHIP. In his most recent outing for the Blue Jays on Wednesday, he pitched three scoreless innings along with five strikeouts, and his fastball topped out at 99.4 mph.

His development this season has illustrated his effectiveness, and if the Blue Jays stretch him out, he has the potential to pitch five to six innings, making him a viable option in the rotation next season.

The 25-year-old has carried himself well, and his versatile role has allowed the Blue Jays to use him as a bulk-reliever, spot starter and long reliever. He has also supported the team's taxed rotation that's also dealt with its fair share of inconsistencies.

Spencer Miles presents a bright future for the Blue Jays

The rookie's dominance this season makes him a strong candidate to provide reliable innings out of the rotation in 2027. With 54 innings pitched this season, he has gained the experience and has surpassed expectations, making him a worthy candidate to be a starter.

The Blue Jays as a team have given up 113 home runs so far this season, but the rotation alone in June has surrendered 24 home runs. The rotation needs reliable arms who can help supply shutdown innings.

Miles' groundball rate of 55.9% sits in the 95th percentile, showcasing his ability to limit hard contact. He represents the exact type of pitcher the Blue Jays need in their future rotation as he has also limited the long ball, only giving up four home runs. His 9.17 strikeouts per nine innings is above the league average and has pointed to his solid swing-and-miss ability with his sinker and high-spin curveball.

All things considered, his emergence as an essential breakout arm has made him an intriguing option for the Blue Jays rotation in 2027. In addition, he represents a significant asset that the San Francisco Giants surely regret letting go in last December's Rule 5 Draft. His dominance is something that could have uplifted their pitching staff this season, but the Giants' loss is a huge gain for the Blue Jays.
