Jenkins was diagnosed with a Grade 1 left hamstring strain after undergoing an MRI on Sunday, Dan Hayes of The Athletic reports.
The Twins' top prospect suffered the injury Saturday when attempting to beat out a double play. Jenkins is without an official timeline for his return, but the injury could affect his availability for the start of the Triple-A season. The 21-year-old received a taste of the Triple-A level late last year and has a decent chance of making his MLB debut at some point in 2026.
