FBaseball Overview

After a disappointing start to 2026 with a .167 average across 120 at-bats, this 28-year-old corner outfielder faces significant fantasy headwinds despite showing moderate power upside with 4 home runs. His 2025 season demonstrated legitimate 20-homer potential with 22 homers and 40 RBIs in a full campaign, but the current year's struggles have eroded both his batting average outlook and run-scoring contributions. The primary concern is consistency at the plate—his sub-.210 career batting average makes him a risky source of batting average points, though his ability to chip in power, RBIs, and occasional runs keeps him relevant in deeper leagues. For 2026, he projects as a bench bat or end-of-roster flier in most formats, with upside only if he can stabilize his contact rate and recapture last year's power production.

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.

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.

LD% — Line drive rate. High LD% hitters make consistent hard contact; line drives are the batted ball type most likely to fall for hits and boost batting average.

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.
