MLB Major League Baseball
Idea Predict MLB games by own-made formulas. Analyze separately on pitchers and batters.
Formula - batters [(AB-SO)×(TB/AB)+BB+SB}×(H/AB)+HR Inning ( 局 ) At Bats (AB, 打數 ) StrikeOuts (SO, 三振數 ) Total Bases (TB, 壘打數 ) Base on Balls (BB, 保送數 ) Stolen Base (SB, 盜壘數 ) Hits (H, 安打數 ) Home Runs (HR , 全壘打數 )
Total bases (TB) A single ( 一壘安打 ) -> TB+1 A double ( 二壘安打 ) -> TB+2
Formula - batters [(AB-SO)×(TB/AB)+BB+SB}×(H/AB)+HR Inning ( 局 ) At Bats (AB, 打數 ) StrikeOuts (SO, 三振數 ) Total Bases (TB, 壘打數 ) Base on Balls (BB, 保送數 ) Stolen Base (SB, 盜壘數 ) Hits (H, 安打數 ) Home Runs (HR , 全壘打數 ) ↑ 打擊率 Batting average ↑ Total Bases (after adjustment)
Formula - batters [(AB-SO)×(TB/AB)+BB+SB}×(H/AB)+HR The scores that the batters can get in a game
Formula - pitchers Starters 先發投手 Relievers 救援投手 pitchers
Formula – starters {[(BF-SO)/IP]×[(BB+H)/IP]×BA‘×IP/G}/α+HR/G total Batters Faced (BF, 面對打者數 ) StrikeOuts (SO, 三振數 ) Innings Pitched (IP, 投球局數 ) Base on Balls (BB, 保送數 ) Games (G, 投球場數 ) BA’ (BA of the opponent, 被打擊率 ) α (own- set scalar for adjustment) ↑ number of batter the possibility that a batter can be on base ↓ ↑ BA of the opponent
Formula – starters {[(BF-SO)/IP]×[(BB+H)/IP]×BA‘×IP/G}/α+HR/G The scores that a starting pitcher may lose in a game
Formula - relievers Starters : scheduled Discussing each pitcher separately Relievers : unscheduled Use the average statistics
Formula – relievers WHIP×(H/IP)×IP‘/α Walks and Hits per Inning Pitched (WHIP) IP’ (average innings that the relievers may pitch, depending on the starter) H/IP: the average hits that a pitcher may allow in a inning
Ratio 60% pitcher (starters and relievers) Ratio of starters and relievers depend on the average innings that a starter can pitch Starters 66.7% last-3-game 33.3% last-10-game Relievers 100% Season 40% batter 62.5% last-7-day 37.5% season
Result
Future Adding more factors Standings ( 戰績 ) Home/away ( 主客場 ) Fielding ( 守備 )
Goal 60+% success rate
