Pitch-Quality Surplus

Two hitters with the same wOBA
are not the same player.

Every public hitting stat conditions on what the hitter did — none of them ask what the pitcher actually threw. We grade all three million pitches a season and measure each hitter's production against what those pitches implied. The gap is your edge.

The blind spot

Same stat sheet. Different hitter.

Hitter A
.340 wOBA built squaring up 97 mph heaters at the top of the zone. Quietly elite.
vs
Hitter B
.340 wOBA built feasting on hanging sliders middle-middle. Quietly lucky.

wOBA, xwOBA, and wRC+ grade both the same. PQS doesn't. It models the expected run value of every pitch from pre-contact quality alone — velocity, movement, location, count, platoon — then credits each hitter with the runs he created above what the pitches themselves implied.

What you get

Boards no leaderboard else can show you

▲ Underrated

High surplus, lagging surface stats. The buy-lows and waiver adds before the crowd sees it.

▼ Overrated

Negative surplus on big names — sell-high candidates and fades before regression shows up in wOBA.

◆ Tough-diet specialists

TPS leaders: who actually produces against the hardest pitching. The hitters you want when playoff matchups get nasty.
