Luis Arraez

Age 29 B/T L/R 5′10″, 186 lb Venezuela MLB debut 2019
40-man
  • Free agent est. 2 yr × $16.3M ($12M–$25M) · +1.1 wins to Pittsburgh’s Winter Plan as a bench bat
    1 caution
    • Big walk year: 4.1 WAR in 2026 against a 1.6-WAR projection. With the walk year at his projection the model would price him at $12.5M a year, not $16.3M. Last winter's 27 deals after such seasons came in about 8% under the estimate on average (± 13%): no clear premium or discount beyond what the model already pays.
  • PNC Park Pittsburgh’s home park: +2.1 runs per 600 PA against an average park (+0.21 wins over 595 PA; his WAR leaves this out); home runs ×0.96 (×0.99 for left-handed hitters as a group). Park Fit →

Does the most damage up and in (+5.0 vs. league per 100; 2.3 standard errors on 85 pitches, inside the noise for the best of nine cells).

Weakest down over the middle (−2.6), but only 1.4 standard errors from average on 154 pitches: no in-zone spot to attack yet.

Runs per 100 pitches vs. an average LHB: better · worse. Catcher’s view · 2,270 pitches · faded cells are within one standard error of average. A spot is called only when it is farther from average than the best or worst of nine average cells gets 95% of the time (set from the league’s own pitches: about 3 standard errors above, 2 below).
