Career Stats + Projections

Real MLB stats plus park-adjusted projections — this season (so far / rest / full), then future seasons and career totals.

show model inputsbasis chips: RAW = as recorded · CTX = with park/league context · A+C = actual + context combined · MLE = level/park-neutral

Methodology▸ how these numbers are built

All seasons translated to park-neutral MLB-equivalent (MLE) and combined per year. 2027 = full-season projection (no games played yet). 2028+ via Advanced Marcel + aging curve. Catcher framing: only 2027 Statcast framing is modeled (Baseball Savant server-caches the leaderboard to the current season); prior-year framing is unmodeled — projections for established framers may run 1-3 WAR low.

One row per minor-league stint. Open a row to see each step: the raw rate, the park adjustment, the league/level factor, the age adjustment (hitters) and the resulting MLE rate. Factors are the same ones listed on the MLE Factors page.

2015 AAAGwinnett Braves · 71 PAwOBA .279 → .224 (−55)K% 19.7% → 25.2%

Component	Raw	Park ÷	Level factor ×	GB/FB ×	Age ×	= MLE
K% /PA	19.72%	÷0.940	×1.200	—	—	25.16%
BB% (unintentional) /PA	11.27%	÷1.103	×0.690	—	×0.940	6.62%
HBP% /PA	0.00%	—	×0.940	—	×0.940	0.00%
Singles /BIP	24.49%	÷0.996	×0.930	×1.050	×0.940	22.56%
Doubles /BIP	6.12%	÷0.988	×0.830	×1.050	×0.940	5.08%

Home runs /BIP	0.00%	÷1.014	×0.840	—	×0.940	0.00%

Factors used: league row IL. Park (home-season share, regressed): HR 103, 1B 99, 2B 98, 3B 98, K 88, BB 121 — applied at half strength. Age: age 38 vs a level average of 27.2 → −6.0% on BB/HBP/hit rates (10.8 yr older than average). Ground-ball/fly-ball mix moves 1B/2B/3B by ×1.050.

Result: wOBA .279 → .224; ISO .048 → .039; BABIP .306 → .276. Both wOBAs use the same linear weights, so the change is the translation alone. The MLE line is not regressed to the mean — regression happens later, when seasons are blended into a projection (how).

Home runs /BIP	0.00%	÷1.000	×0.780	—	×0.940	0.00%

Factors used: level-wide ROK factors (no league-specific row for this league/era). Park (home-season share, regressed): no park row on file (treated as neutral) — applied at half strength. Age: age 37 vs a level average of 19.5 → −6.0% on BB/HBP/hit rates (17.5 yr older than average).

Result: wOBA .330 → .238; ISO .105 → .074; BABIP .278 → .204. Both wOBAs use the same linear weights, so the change is the translation alone. The MLE line is not regressed to the mean — regression happens later, when seasons are blended into a projection (how).
