Baseball statistics, strategy and simulation

Baseball keeps a statistic for almost everything, and most of them measure one thing at a time. Batting average counts hits, on-base percentage counts times on base, slugging weights extra bases, and ERA and WHIP describe a pitcher from two different angles. Knowing which number answers which question is most of the work of reading a roster, and it is what these guides are built around.

Two of our apps sit beside them. 162-0 Baseball Draft & GM Team has you draft nine players and a coach, compare hitters and pitchers on the numbers, and see what record the club projects over 162 games. Baseball Career Sim 2026 follows a single player — hitter, pitcher, catcher or two-way star — from school through the draft into the professional game. The guides explain the sport first and the games second.

Our baseball apps

162-0 Baseball Draft & GM Team is about assembling a club: a position-by-position draft compared on statistics such as ERA, WHIP, on-base ability and WAR, a projected 162-game record, and a Franchise GM Mode for the batting order, rotation, bullpen and payroll. Baseball Career Sim 2026 is about one player: you choose the position and archetype, then play through innings, counts, runners and bullpen decisions as the career develops. The GM game suits anyone who likes reading a stat sheet; the career sim suits anyone who wants to live a season at a time.

Where to start

  • Start with the basic rate statistics

    Batting average, on-base percentage and slugging percentage are all defined in Rule 9.21 of the Official Baseball Rules, and each answers a different question. The beginners’ guide and the OPS explainer walk through them, and the batting average calculator computes them from a hitter’s line.

  • Read pitchers on more than one number

    ERA charges a pitcher for earned runs, WHIP for baserunners, and strikeout and walk rates for the outcomes a pitcher controls most directly. The ERA and WHIP explainers show where each one misleads; the ERA calculator handles innings written as 6.1 and 6.2.

  • Then choose the side of the game you want

    Batting orders, roster construction and the projected record belong to the GM side. Pitching roles, two-way players and aging curves matter most over a single career.

Baseball: common questions

What is the difference between 162-0 Baseball Draft & GM Team and Baseball Career Sim 2026?
162-0 Baseball Draft & GM Team is a draft and general-manager game: you draft nine players and a coach, the season simulator projects a 162-game record, and Franchise GM Mode covers the batting order, rotation, bullpen and payroll. Baseball Career Sim 2026 is a career simulator: you create one hitter, pitcher, catcher, closer, utility player or two-way star and take that player through school, the draft and the professional years.
How is on-base percentage calculated?
Under Rule 9.21 of the Official Baseball Rules, on-base percentage is hits plus walks plus hit-by-pitches, divided by at-bats plus walks plus hit-by-pitches plus sacrifice flies. Reaching base on an error or a fielder’s choice does not count. The batting average calculator applies the same formula.
Does 162-0 Baseball Draft & GM Team use live results?
No. Its season record is a projection built from roster quality, position fit, hitting, pitching, speed, defence and coaching, and there is no online multiplayer.
Where should a newcomer to these guides start?
With baseball statistics explained for beginners, then the ERA and WHIP explainers and the baseball draft simulator guide.
