Theo Gillen Fantasy Stats

The Tampa Bay Rays top outfield prospect Theo Gillen is having a very good age-20 season between two levels of the minors in 2026. Now with Double-A Montgomery, Gillen has hit .320 combined between two teams with 20 homers and 74 RBI to go with 78 runs and 39 stolen bases. The left-handed hitting outfielder is producing in all five categories and offers a very balanced statistical profile for future fantasy leagues. But right now, Gillen may need more nurturing in the minors and could be looking at a few years down the road for a major-league debut. He's a name to remember, however, because of his 60-grade hit tool and 60-grade speed. He could be a very appealing power-speed combination in years to come. Dynasty managers will want to snatch him up for future teams as he looks like a potential stud.

Tampa Bay Rays outfield prospect Theo Gillen extended his 13-game hit streak with a two-homer performance on Wednesday night for Double-A Montgomery and continued his red-hot month of July. In 68 at-bats for Montgomery in July, Gillen has six homers, 22 RBI, 14 runs scored, and seven stolen bases, all while hitting .338. At age 20, Gillen is the top prospect for the Tampa Bay Rays. He's split time between High-A Bowling Green and Montgomery this season and is on a tear at Double-A. Earlier this season at Bowling Green, Gillen was equally impressive with 12 homers and 44 RBI to go with 53 runs scored and 28 stolen bases while hitting .342. Blessed with a 60-grade hit tool and a 60-grade run tool, Gillen is a rare prospect to monitor. But it still might be a bit before he reaches Tampa Bay, as he is just 20 years old.

Tampa Bay Rays outfield prospect Theo Gillen snapped his lengthy power skid at Double-A. On Friday evening, the team's No. 1-ranked prospect (according to MLB.com) went 2-for-3 with a double and a home run. This snapped a lengthy 14-game power drought for Gillen since moving up to the Double-A level. The outfielder spent the first half of the season at the High-A level, where he posted a .342/.449/.589 line with 23 doubles, 12 home runs and 28 sotlen baes. However, it took him some time to find his footing at Double-A, as he posted a low .190/.277/.241 line thorughh is first 14 games at the level. Dynasty managers should continue to keep a close eye on his progression at Montgomery as the No. 9-ranked prospect on MLB Pipeline could put himself in a great position to begin the 2027 season at Triple-A Durham.

Tampa Bay Rays outfield prospect Theo Gillen has seen his productivity surge dramatically over the first half of the season. Entering the All-Star break, the former 18th overall pick from the 2024 MLB Draft is now listed as MLB.com's No. 9-ranked prospect (in all of baseball) and Tampa Bay's No. 1 prospect. Gillen began the 2026 season at the High-A level, where he produced at an elite level, carrying a .342/.449/.589 line with a 1.038 OPS. During this 57-game stretch, Gillen hit 12 home runs and swiped an impressive 28 bags. He has since been moved up to Double-A, where he has posted a .180/.268/.240 line with no home runs. However, given that he is only 20 years old, managers should expect some growing pains. While a 2026 debut is highly unlikely, Gillen could enter the 2027 season as a consensus top-10 prospect if he maintains this pace.
