Much the same as fantasy league players love baseball, sports bettors love it, too. Both gamers appreciate its predictability. (A wonder, then, that more fantasy league players don't bet baseball.) One, teams and players generally perform according to historical averages, and, two, both players and, more important to bettors, teams streak. Hitters go on a tear, pitchers can't be touched for a month at a time, and teams rattle off eight or nine wins in a row or even go Oh-for-the-Coast if the Western Division teams are playing well.
How can the sports bettor interpret this matrix of percentages to her or his advantage? One, pick a handful of teams which you expect to compete for a division championship or even a league pennant (WINNERS) and a handful of teams which you expect to muddle along at best (LOSERS). The WINNERS you should expect to tally 85-95 victories, the loser to drop 95-105 games. Look for matchups of the former against the latter, then bet the series, or, make the same bet for two or three days in a row while the LOSER visits the WINNER's home ballpark.
Two, bet on strong pitching. Every team manager tries to arrange his pitching rotation to start his best pitcher in the first game of as many series (especially at home in front of supportive fans in a familiar stadium) as possible (generally against the other team's best pitcher). By the second and particularly third game of a series, the WINNER should still be sending a quality pitcher to the mound to start the game while the LOSER hopes for the best with what it has in the bottom half of its rotation.
Of course the oddsmakers know all these tricks, too, and will build the WINNER/home-team advantage into the odds on the game; still, Master, is it not better to cash a short-odds bet than to lose on a long-shot?
