Barco (elbow) began a rehab assignment in the rookie-level Florida Complex League on July 20 and has turned in a 1.00 ERA, 0.67 WHIP and 12:2 K:BB across nine innings over his first three appearances.
Barco is technically on Triple-A Indianapolis' 60-day injured list, but once he's activated, he'll likely remain in the FCL or head to Single-A Bradenton. The 44th overall pick in the 2022 First-Year Player Draft, Barco didn't make his professional debut last season while he recovered from Tommy John surgery.
