FBaseball Overview

Coming off a disappointing 2026 campaign after a promising debut year, Marsee offers primarily speed upside in the stolen base category with 18 swipes, though his batting average has cratered to .193—a stark 99-point decline from his .292 rookie season. The 25-year-old's power remains modest and his run production has declined across the board, suggesting he's struggling to adjust to MLB pitching after an encouraging first taste. His elite speed tool remains an asset for deep leagues targeting steals, but he's a risky play in standard formats until he demonstrates he can recover at the plate and recapture the offensive form he displayed in 2025. Marsee needs to reverse course immediately in 2027 to remain a viable fantasy option beyond specialty leagues.

What These Stats Mean

EV Avg — Average exit velocity — how hard this batter hits the ball. Elite hitters (90+ mph) make consistently hard contact, driving better batting averages and more power.

Max EV — Peak exit velocity on the batter's hardest-hit ball this season. Signals raw power potential even without a high HR total yet.

Launch Angle — Average vertical angle of the ball off the bat. The sweet spot for extra-base hits is roughly 10–30°; extreme ground ball or pop-up hitters sit outside this range.

Barrel % — Percentage of batted balls hit with the optimal exit velocity + launch angle combo. Barrels are the single best predictor of home runs and slugging percentage.

K % — Strikeout rate per plate appearance. High K% suppresses batting average and limits run-scoring opportunities — lower is better for fantasy.

Hard Hit % — Percentage of batted balls hit 95 mph or harder. A broader power indicator than barrels; high hard-hit% players rack up extra-base hits and RBI.

Sprint Speed — Peak sprint speed in feet per second. The best predictor of stolen base upside and ability to leg out infield hits.

Bat Speed — Average swing speed at the point of contact. Faster bat speed lets hitters wait longer on pitches and generates more raw power potential.

Whiff % — Percentage of swings that miss. High whiff rates signal strikeout vulnerability, dragging down batting average and overall production.

Chase % — How often the batter swings at pitches outside the strike zone. Low chase rates mean elite plate discipline — more walks, fewer strikeouts, more consistent at-bats.

xBA — Expected batting average based on contact quality, stripping out luck and defensive positioning. Better predictor of future performance than actual batting average.

xSLG — Expected slugging based on batted ball data. A high xSLG relative to actual SLG suggests power suppressed by bad luck that's likely to bounce back.

xwOBA — Expected weighted on-base average — the most comprehensive single expected metric. Combines contact quality, walks, and strikeouts to project overall offensive production.

GB% — Ground ball rate. High GB% hitters trade home run power for speed-dependent value — good for stolen base upside, but a drag on HR and SLG categories.

FB% — Fly ball rate. Elite power hitters combine high FB% with high exit velocity. High fly ball rate + soft contact = home run or nothing type.
