Guides, tips, and deep dives on the free browser baseball card game powered by real MLB Statcast data.
Junior Caminero has hit 8 HRs in his last 14 games with a 95.8 mph average exit velocity and a .521 xwOBA — every contact metric now sits in the 97th percentile or better.
Hard Hit Rate is the percentage of a hitter's batted balls struck at 95 mph or harder off the bat, a Statcast quality-of-contact measure that correlates strongly with power and expected slugging.
Pop time is the number of seconds from the instant a pitch hits the catcher's mitt to the instant the ball reaches the fielder's glove at the base on a throw to second or third, measuring a catcher's total throw-down quickness.
xBA (expected batting average) is a Statcast metric that estimates what a hitter's batting average should be based on the exit velocity, launch angle, and sprint speed of each batted ball, stripping out luck and defense.
A cutter is a fastball variant — typically 2-5 mph slower than a four-seamer — that breaks late toward the pitcher's glove side, splitting the difference between a fastball and a slider.
Stuff+ is a pitch-quality model that rates the physical nastiness of a pitch — velocity, spin, and movement — on a scale where 100 is MLB average and every 10 points equals one standard deviation.
Whiff rate is the percentage of a batter's swings that miss the ball — calculated as swings-and-misses divided by total swings — and is the cleanest single measure of a pitch's bat-missing ability.
A sweeper is a breaking pitch thrown in the low-to-mid 80s with exaggerated horizontal break—often 15 to 20 inches—and minimal vertical drop, classified by Statcast as a distinct pitch from the traditional slider.
Bat speed is the velocity of the bat's sweet spot at contact, measured in miles per hour by Statcast's Hawkeye system, with an MLB league average near 71 mph and elite hitters exceeding 75 mph.
Catcher framing is the skill of converting borderline pitches into called strikes through pitch receiving, measured by Statcast as the difference between actual and expected called-strike rate in the shadow zone.
A slider is a breaking pitch thrown between 78 and 92 mph that moves laterally and downward, sitting between a fastball and a curveball in velocity and break.
BABIP (Batting Average on Balls in Play) measures how often a hitter reaches base on balls put in play, excluding home runs and strikeouts, with league average hovering near .300.
wRC+ (Weighted Runs Created Plus) is a park- and league-adjusted measure of total offensive value where 100 is league average and every point above or below equals one percent better or worse than average.
The Dodgers (15-6), Braves (15-7), and Reds (14-8) pulled away from their divisions the week of April 13–19, 2026, while Yordan Álvarez's 8-homer line, Elly De La Cruz's 442-foot bomb, and Masataka Yoshida's pinch-hit walk-off over Detroit headlined the action.
OAA (Outs Above Average) is Statcast's primary defensive metric, measuring how many outs a fielder converts above or below what an average fielder would produce given identical opportunities.
Spin rate is the number of times a pitched baseball rotates around its axis per minute (RPM), measured by Statcast, and is a primary driver of pitch movement and swing-and-miss rates.
WAR (Wins Above Replacement) measures how many wins a player contributes above what a freely available replacement-level player would provide, combining offense, defense, baserunning, and pitching into a single number.
A barrel is a batted ball hit at 98+ mph exit velocity with a launch angle in a specific run-productive window — a combination that has historically produced a .500+ batting average and 1.500+ slugging. Barrel rate is the share of a hitter's batted balls that qualify. It is the single best predictor of sustainable power.
Exit velocity is the speed of the baseball as it leaves the bat, measured in miles per hour by the Hawk-Eye tracking system in every MLB stadium. It is the cleanest measurement of raw contact quality and the single largest input into modern hitter evaluation.
FIP (Fielding Independent Pitching) is a pitcher's ERA estimator built only from strikeouts, walks, hit-by-pitches, and home runs — outcomes the pitcher controls directly, independent of the defense behind him.
Launch angle is the vertical angle at which the ball leaves the bat after contact, measured in degrees by Statcast's optical tracking. It determines whether a batted ball becomes a ground ball, line drive, or fly ball — and pairs with exit velocity to define the full shape of a hitter's power profile.
Park factor is a ratio that captures how much a specific ballpark inflates or depresses offensive events (runs, home runs, hits) relative to a neutral environment. It is the correction that lets analysts fairly compare a Coors Field hitter to a Petco Park hitter — and the reason Legends Deck card ratings already adjust for ballpark effects.
Sprint speed is the average top-end running speed of a player, measured in feet per second during their fastest one-second window on qualified plays. It is the single cleanest measurement of raw athletic speed in baseball and drives infield hit rates, extra-base taking, and defensive range.
wOBA (weighted On-Base Average) is a rate stat that credits each offensive event — walk, single, double, triple, home run — by its actual run value, then scales the result to the familiar OBP range. It is the single most accurate summary of a hitter's offensive production on the 0–1 scale.
xwOBA (expected weighted On-Base Average) is Statcast's quality-of-contact metric that estimates what a hitter's wOBA should be based purely on exit velocity, launch angle, and (for speed-dependent balls) sprint speed. It strips out luck, defense, and ballpark to reveal true underlying offensive skill.
Every Legends Deck card rating is derived from real Statcast percentiles — no editorial opinions, no manufacturer curves. This is the full breakdown of how hitter and pitcher ratings are calculated, why they sometimes surprise you, and how to read a card to know whether it's a buy or a sell.
Statcast is MLB's radar-and-camera tracking system that measures every pitch, swing, and sprint at the major-league level. Legends Deck turns that data — exit velocity, barrel rate, xwOBA, sprint speed — directly into card ratings, so every card reflects how a real player is actually performing right now.
You do not need a maxed-out wallet to compete in Legends Deck. This guide covers the cheapest high-impact cards in the 2026 marketplace — overlooked contact hitters, high-spin relievers, and value shortstops — along with a crafting path that upgrades them to elite tier.
Franchise Mode is Legends Deck's full-season, front-office simulation: 162 games, farm system development, trades, the amateur draft, arbitration, playoffs, and the Hall of Fame. This guide walks through every system and the non-obvious strategies that separate dynasty rosters from also-rans.
