[Hector Rodriguez]

Arizona outfielder Brendan Summerhill is one of the most well-rounded prospects in the 2025 MLB Draft. Could he be an option for the Miami Marlins with their first-round pick? 

Overview

Position: OF

Height: 6’3″

Weight: 200 pounds

School: Arizona

Brendan Summerhill is a 6’3”, 200-pound outfielder who plays at the University of Arizona. Summerhill is one of the top collegiate bats in the 2025 MLB Draft and also one of the top pure hitters available.

On MLB Pipeline, Summerhill is the tenth-ranked prospect and the second-ranked outfielder in the 2025 draft class. He’s also ranked #8 on Just Baseball and #19 on Baseball America.

During his time at Arizona, Summerhill has a career .334/.426/.555 slash line. After playing sparingly as a freshman, Summerhill had a major breakout season for the Wildcats. In his sophomore season, Summerhill slashed .324/.399/.550 with 77 hits, eighteen doubles, six triples, eight home runs, 59 RBIs, and a .950 OPS. He was also named to the 2024 All-Star Team in the Cape Cod Summer Collegiate League.

In his junior season, Summerhill continues to produce at the plate for the Wildcats. Summerhill is slashing .409/.500/.656 with 38 hits, five doubles, six triples, two home runs, 24 RBIs, a .462 BABIP, a 168 wRC+, and a 1.156 OPS. Summerhill has an 87.3% contact rate and a 90% in-zone contact rate. He does a good job of keeping his chase rate down at 15.3%.

At the plate, Summerhill is an advanced hitter with clean hitting mechanics and a disciplined approach. He’s a line-drive hitter who can drive the ball to all fields, but most of his power comes from the pull side.

During the 2025 season, Summerhill has a low 11.8% strikeout rate and a 14.5% walk rate. He has also improved his average exit velocity from 87 mph to 91.7 mph and could add more power to his game as he continues to fill in his frame.

Summerhill has played right field at Arizona, but projects to be a center fielder at the next level. He solely played center field in the Cape Cod League.

Bottom Line

Brendan Summerhill is a quality collegiate bat who does a lot of things well at the plate and defensively. The Chicago native seems like a high-floor prospect who already has a great approach at the plate and can consistently make contact with pitches in the zone. It’s good to see his average exit velocity trend in the right direction, and Summerhill could even add more power to his game as he fills in his 6’3” frame. If that happens, Summerhill will likely move to right field, which isn’t an issue for him thanks to above-average arm strength.

Summerhill is a player to watch until the end of the collegiate season. He could be on Miami’s radar with the seventh overall pick in the 2025 MLB Draft.
