Moving up to Double-A Gillen was promoted to Double-A Montgomery on Sunday, Marc Topkin of the Tampa Bay Times reports.

Impact Gillen will move up to Double-A after posting an impressive .342 average with 12 home runs, 44 RBI, 53 runs scored and 28 stolen bases over 219 at-bats in 57 contests with High-A Bowling Green this season. The 20-year-old is considered to be one of Tampa Bay's top overall prospects, and he'll have a shot to climb to the Triple-A level before the end of the year.

Scorching for Hot Rods Gillen is hitting .333 with four home runs, three steals and a 22.6 percent strikeout rate in eight games for High-A Bowling Green.

Impact Gillen had an excellent first full season last year (151 wRC+ in 73 games at Single-A), save for the fact he didn't hit for much over the fence power (five home runs, .119 ISO). Less than 10 games into his first season at High-A and he's already one homer shy of tying his career high. Gillen leads the Sally league in ISO (.556) and wRC+ (251), but the Rays will likely keep him there for at least another couple months before challenging the 20-year-old center fielder with a bump to Double-A.

Makes spring debut Gillen (undisclosed) played three innings in center field and drew an eight-pitch walk in his lone plate appearance in Sunday's 5-3 loss to Atlanta in Grapefruit League play.

Impact Gillen closed the 2025 campaign on Single-A Charleston's injured list due to an unspecified issue and has been limited to just 81 total games since being selected in the first round of the 2024 First-Year Player Draft, but the athletic outfielder reported to camp healthy and has drawn raves from the Rays' coaching staff. After Gillen impressed Sunday in his limited action in his spring debut, manager Kevin Cash told Marc Topkin of the Tampa Bay Times that he plans to have the 20-year-old play in a few more exhibitions prior to the end of camp. Gillen will likely head to Charleston or High-A Bowling Green for the start of the 2026 campaign.
