The Pittsburgh Pirates are in talks to lock up their top prospect, Konnor Griffin, with a long-term contract before he reaches the big leagues. At 19, Griffin is regarded as one of baseball’s premier prospects and has opened the season with Triple-A Indianapolis — yet the organization is already weighing an extension that would buy out his pre-arbitration and early arbitration years.
agreements of this kind have become more common, and they carry upside and risk for both clubs and players. Below I break down the precedent: seven other players who signed significant deals before accumulating MLB service time, ranked and analyzed to provide context for what the Pirates — and Griffin — might be signing up for.

Clubs pursue early extensions to secure cost certainty and, ideally, a franchise cornerstone at a controlled salary. For prospects, the appeal is guaranteed money and financial security in exchange for potentially forfeiting higher earnings later if they become stars. The results have been mixed — some teams landed bargain superstars, others paid for unrealized upside.
- Benefits for clubs: payroll predictability, retention of a homegrown talent during prime years.
- Benefits for players: immediate financial security and protection from injury risk.
- Risks: teams may overpay for players who never reach predicted ceilings; players may leave money on the table if they blossom into elite stars.
Past pre-service deals ranked: a look at outcomes and value
Below are seven players who signed long-term contracts before or very early in their MLB careers, ordered from least to most favorable outcome based on on-field production, cost, and longevity. Two other recent pre-debut signees — Colton Emmerson and Cooper Pratt — are not included because their deals are too new to evaluate.
-
Evan White — Seattle Mariners
Line: .165/.235/.308 • WAR: -0.7 • HR: 10 • Deal: 6 years, $55.5M
White’s extension ranks lowest. Seattle guaranteed over $55 million for a player who barely stayed on the major-league roster. While he earned a Gold Glove in the pandemic-shortened 2020 season, his offensive output never stabilized, and his time with the club ended prematurely compared with the contract’s term. That mismatch between contract length and production made this a costly experiment for the Mariners.
-
Jon Singleton — Houston Astros
Line: .197/.299/.345 • WAR: -1.3 • HR: 29 • Deal: roughly $10M
Singleton’s case is complicated by off-field issues and an uneven career trajectory. His contract size was relatively modest, which limited Houston’s downside, but performance and availability problems kept him from ever validating the gamble. He spent parts of multiple seasons out of organized ball, so while the financial hit was limited, the on-field return was disappointing.
-
Scott Kingery — Philadelphia Phillies
Line: .227/.278/.382 • WAR: -0.2 • HR: 30 • Deal: 6 years, $24M
Kingery showed flashes, including a season that approximated league average and produced 2.7 WAR, but overall he fell short of expectations. Philadelphia’s six-year commitment represented a medium-sized bet that ultimately didn’t pay off; a single useful season didn’t justify the multi-year guarantee when weighed against the other poor stretches.
-
Eloy Jiménez — Chicago White Sox
Line: .269/.318/.462 • WAR: 5.3 • HR: 95 • Deal: 6 years, $43M
Jiménez sits in the middle of this list. He signed a sizeable deal before his MLB debut and delivered powerful offensive seasons — including a 31-homer rookie campaign and a strong OPS+ year in 2022 — but injuries and inconsistency reduced his ceiling. Jiménez’s highs were legitimately impactful, but durability concerns and some below-average stretches temper the contract’s overall value.
-
Colt Keith — Detroit Tigers
Line: .261/.323/.398 • WAR: 2.6 • HR: 26 • Deal: 6 years, $28.6M
Keith represents a forward-looking, team-friendly agreement. After a shaky rookie year, he settled into a versatile everyday role, offering multi-position value and improving performance. While his peak hasn’t matched the elite hitters above him, his flexibility and steady progress make his contract look like a reasonable investment for Detroit if he continues to develop.
-
Jackson Chourio — Milwaukee Brewers
Line: .272/.317/.463 • WAR: 6.1 • HR: 42 • Deal: 8 years, $82M
The Brewers took a notable swing on Chourio, and so far it’s paid dividends. The eight-year, $82 million pact secured a talented, above-average contributor at what appears to be reasonable market value. Chourio hasn’t yet become a perennial All-Star, but his production has been valuable for Milwaukee’s lineup and rotation support. Over the long haul, his contract is shaping up as smart risk management by the club.
-
Luis Robert Jr. — Chicago White Sox / New York Yankees
Line: .260/.314/.455 • WAR: 15.8 • HR: 103 • Deal: $26M (pre-debut)
Robert is the most successful example among these early extensions. He reached an All-Star game, posted elite power numbers in peak seasons, and delivered top-tier value during the first years of his contract. Injuries clouded parts of his tenure in Chicago, but when healthy he produced at a high level — making the original pre-debut agreement look like a bargain for the club that locked it up early.
Key takeaways for front offices and prospects considering early deals
- Durability matters: Long-term payoffs hinge on staying healthy. Several deals faltered primarily because the player missed significant time.
- Contract size and term: Lower guarantees and team-friendly structures reduce risk for clubs while still offering security to players.
- Positional value and versatility: Players who can play multiple positions or provide consistent offensive value better justify early extensions.
Implications for the Pirates and Konnor Griffin
For Pittsburgh, signing Griffin would be both a statement and a strategic bet. The organization would secure control of a consensus top prospect while signaling commitment to contention. For Griffin, a long-term deal offers immediate security but could limit his future earnings if he blossoms into a perennial All-Star.
Given how mixed the historical outcomes have been — from clear bargains to missed bets — the specific terms the Pirates propose will matter enormously. Structure, guaranteed money versus incentives, and injury protections will shape whether this agreement becomes a franchise win or a cautionary tale.
