Zack Gelof -- Prospect Evaluation

Zack Gelof has emerged as a breakout prospect for the Oakland Athletics, jumping from an unranked 64th-ranked third baseman in 2022 to the Dynasty Guru's 10th overall prospect in 2023 at a new position, second base. Before professional baseball, Gelof demonstrated excellence both athletically and academically as Delaware's Gatorade Player of the Year while maintaining straight-A grades and serving as four-time class president. After being drafted in the second round in 2021 following his junior year at University of Virginia—where he started all three seasons and reached the College World Series—Gelof began his professional career in 2021 with a strong Low-A Stockton performance (.298/.393/.548, 7 HR, 11 SB, 13.1% walk rate over 145 PA). In 2022, Gelof spent most of the season in Double-A Midland, posting a .271/.356/.438 line with 13 home runs and a 11.7% walk rate over 402 plate appearances. While his power grades only at 55, he demonstrates exceptional plate discipline and efficiency in maximizing his power output. A shoulder injury (torn labrum) caused him to miss six weeks mid-2022 while diving for a ground ball.

Zack Gelof, drafted in the second round by the Oakland Athletics this year, has rapidly impressed the organization after just two months following his College World Series appearance at Virginia. Called up to Triple-A Las Vegas to address injuries in Oakland's major league roster, Gelof demonstrated immediate impact with 7 hits in 12 at-bats and 6 RBIs in 36 games. Prior to his Triple-A assignment, he batted .298 with 7 home runs and a .941 OPS in 32 games for Low-A Stockton. A's farm director Ed Sprague praised Gelof's overall approach and power potential, while scouting director Eric Kubota highlighted his exceptional athleticism for his size (6-foot-3, 205 pounds). The Athletics believe Gelof possesses plus speed, excellent baserunning ability, and the potential to become a plus defender, though his primary position remains undetermined pending arm strength recovery from a previous college injury. The organization considers him a top prospect, with Sprague surprised the player reached them in the second round. Additionally, the Athletics assigned corner infielder Jonah Bride to the Arizona Fall League to develop catching skills, while catcher Tyler Soderstrom returned to rehab after a setback, with team doctors diagnosing an oblique injury requiring rest before spring training.

Zachary Dunn Gelof is a 6'2", 205-pound right-handed batter from Rehoboth Beach, Delaware, who was drafted 60th overall by Oakland in 2021 out of the University of Virginia. He was the 2018 Delaware Gatorade Player of the Year and has consistently performed at the plate throughout his career, batting .300/.380/.464 with eight home runs in 57 games during his final college season.

Gelof possesses above-average raw power that plays primarily to the pull side, with most homers traveling to left field, though he demonstrates opposite-field capability. He shows no difficulty catching up to fastballs and has lowered his strikeout rate. However, scouts identify significant weaknesses against secondary pitches and breaking balls, where he struggles with recognition and execution. His swing mechanics occasionally become unbalanced at times.

Defensive assessment remains divided among scouts. Some view him as an above-average third baseman with average arm strength, while others project him moving to a corner outfield position due to inconsistent throws from multiple arm slots. Gelof is an average runner but excels in base-running situations, with an 82% stolen base success rate. Since his MLB debut on July 15, 2023, he has been hindered by multiple injuries, including right wrist surgery and a left shoulder dislocation requiring rehab assignments and roster moves.

Zack Gelof, a 22-year-old prospect for the Oakland Athletics, is characterized as a reliable future contributor with a power-oriented skill set. Drafted 60th overall in 2021, Gelof reached Triple-A following a strong 2022 season in which he posted a .270/.352/.463 slash line with 18 home runs, primarily at Double-A Midland, and added three more home runs in the Arizona Fall League. FanGraphs prospect analyst Eric Longenhagen describes Gelof as having a "power-over-hit profile," noting that while his 70% contact rate was not exceptional, his peak power and barrel rates were encouraging. The right-handed infielder was originally drafted as a third baseman but transitioned to second base during 2022, where he has proven proficient defensively despite not being an elite glove player. When asked for a self-scouting report, Gelof emphasized his athleticism and competitive nature, stating he focuses on improving all aspects of his game rather than being defined by current evaluations. The Athletics, operating on a low budget, view Gelof as a priority to develop alongside higher-ceiling prospect Tyler Soderstrom as they work to build a competitive roster.
