Hometown bias noted, but one poster would not trade Seattle center fielder Taylor Trammell for Jarren Duran, who is a year older than Trammell.
Trammell and Duran had disappointing MLB debuts this year, although Duran was more disappointing.
JD 112 PA, .215/.241/.336/.578, 51 OPS+, -0.7 bWAR, -0.5 fWAR
TT 178 PA, .160/.256/.359/.615, 71 OPS+, -0.3 bWAR, -0.1 fWAR
In small samples, Duran was the clearly inferior defensive center fielder with -5 Defensive Runs Saved and -28.8 UZR/150 in 215 innings while Trammell posted 0 DRS and 0.1 UZR/150 in 312.2 innings.
Each enjoyed some success hitting at Triple A this year, although Duran had the edge:
JD 283 PA, .258/.357/.516/.873, 132 wRC+
TT 323 PA, .263/.362/.456/.818, 104 wRC+
The FanGraphs Prospect Report has curious values for the two 2021 Graduates:
JD Hit 45/55, Game Power 30/35, Raw Power 45/45, Speed 70/70, Field 35/40, FV 50
TT Hit 40/45, Game Power 40/50, Raw Power 55/55, Speed 70/70, Field 60/70, FV 45
Duran's Game Power rating may be low but the other values do not seem to support the ultimate Future Values (FV).
Steamer projects 2022 WAR of 0.8 in 115 games for Duran and 0.1 in 21 games for Trammell.
Duran and Trammell played in the 2019 Futures Game (Trammell's second) but Duran entered Top 100 prospect lists only this year. MLB.com currently ranks Duran at No. 25.
Trammell lost his prospect status in 2021 after entering the season at the 100th-ranked prospect at MLB.com and 72nd-ranked prospect at Baseball Prospectus. In 2019 Trammell ranked No. 16 at MLB.com and No. 11 at BP.
Duran and Trammell each have six years of team control. Baseball Trade Values assigns median surplus trade values of $20.1 million for Duran and $5.1 million for Trammell.
Perhaps each is destined to be a "classic 4A ballplayer, a Triple A star."
Or not.
