FBaseball Overview

At 35 years old, Semien provides veteran stability at second base for the Mets but carries significant regression concerns after a disappointing 2026 campaign. His .214 average and modest 9 home runs through 290 at-bats represent a notable decline from his 2025 production, signaling potential age-related decline or prolonged slump. While he still contributed 30 runs and 6 stolen bases, his 29 RBIs suggest reduced run-production opportunities or inconsistent performance in clutch situations. Fantasy managers should approach Semien cautiously as a bench option or late-round value pick, banking on a potential second-half resurgence from a player who has earned three All-MLB selections and multiple All-Star nods earlier in his career.

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.
