THE APEX TIMES
In MLB Pipeline’s annual ranking of rookies based on expected career value, Pirates shortstop Konnor Griffin landed the top spot as baseball’s best long-term rookie bet, followed by Tigers infielder Kevin McGonigle.
MLB Pipeline’s 2026 long-term rookie value rankings place Konnor Griffin first and Kevin McGonigle second, repeating the exact 1-2 order it had at the start of the season on the Top 100 prospects list. The list is designed to project the most future career value, not to reward who performed best in the short term.
Griffin, a Pirates shortstop who debuted in April at age 19, is credited with an early big league impact followed by a setback. MLB Pipeline’s assessment says he starred in May before two injuries sidelined him for much of the next three months, limiting how long his peak production could play out over the full year.
The publication also ties Griffin’s ranking to upside, citing an archetype of offensive and defensive value. Its projection frames him as a potential high-end bat with power and speed, paired with Gold Glove-caliber defense at shortstop.
McGonigle enters the list as the runner-up after a standout first season. MLB Pipeline notes he led all American League rookies with 7.1 WAR (Baseball Reference style) and that his rookie WAR ranks among the highest ever by a rookie, while also emphasizing the combination of both a high floor and high ceiling at the position.
The ranking includes only players who have graduated from rookie or prospect status by meeting thresholds such as 130 at-bats or certain service-time limits, which is intended to control for who is actually eligible for long-term projection.
