Instead of using the JM baseball thread to discuss and track my system, I figured it was time to start a new thread. The details of my system can mostly be found here:
That posts lists the filters, which I'm going to copy below. The premise of the system is that most teams rarely get swept at home during a 4-game series, so you wait for a 4-game series in which the home team loses the first game, then the next three games become a 3-game chase.
Here are the filters:
A HOME TEAM WINS FIRST GAME (GAME "0") OF FOUR GAME SERIES (GAME 2 IS GAME A, GAME 3 IS GAME B, GAME 4 IS GAME C)
B HOME TEAM HAS HOME WINNING PERCENTAGE UNDER .425
C VISITING TEAM HAS OVERALL WINNING PERCENTAGE OVER .645
D HOME TEAM HAS WON 9 OF LAST 10 AT HOME LEADING INTO SERIES
E HOME TEAM HAS LOST 9 OF LAST 10 AT HOME LEADING INTO SERIES
F HOME TEAM IS IN LAST PLACE AND VISITING TEAM IS IN FIRST PLACE (INCLUDING TIES) LEADING INTO SERIES (REGARDLESS OF DIVISIONS OR OVERALL RECORDS)
G LATE IN SEASON AND BOTH TEAMS ARE ELIMINATED FROM PLAYOFFS
H HOME TEAM HAS OVERALL WINNING PERCENTAGE UNDER .375
J HOME TEAM, LEADING INTO SERIES, HAS NO STARTER WITH ERA UNDER 4.80 SCHEDULED TO PITCH IN THE THREE GAMES ON WHICH TO BET (GAME "0" DOESN'T COUNT)
K HOME TEAM HASN'T HAD A DAY OFF IN THE PREVIOUS 12 DAYS LEADING INTO SERIES (MEANING POTENTIAL C GAME WOULD BE ON 16TH STRAIGHT DAY)
L TWO OR MORE OF ANY OF THE ABOVE FILTERS ARE *ALMOST* APPLICABLE
M GUT FEELING, INDEPENDENT OF ANY FILTERS, TELLS YOU TO STEER CLEAR OF THE SERIES
I've attached a screenshot of the spreadsheet I'm using to track the system. So far, it's undefeated this year and I'm up almost 7 units. Enough of the season has been played so the filters become relevant.
Tampa is definitely a play against Cleveland starting Friday. The Royals are a play according to the system, but if Greinke doesn't lead his team to a win over Baltimore on Friday, the Kansas City starters scheduled for Saturday and Sunday both suck. Also, the forecast calls for showers on Friday, and then good weather on Saturday and Sunday. Play the Royals at your own risk. The Giants are filtered out because they haven't had a day off since April 30, so even if they lose the game that's going on right now, it's still not a play. I'm probably going to play it anyway if the Mets hold their 4-2 lead in this game, because I'm a dick.
I would advise to NEVER play the -1.5 runline on this system. Whether you choose to play the +1.5 runline or moneyline is your decision and should be based on money management rather than baseball strategy. Obviously you're going to have to pay for the +1.5 runs, which will get costly if (when) you lose a series. Assuming -170 odds when you play the +1.5 runline, one series loss will wipe out 18.7 series wins. Assuming +100 even money when playing the moneyline, one series loss will wipe out 7 series wins. And for the novices who don't know the difference, it's inevitable that eventually there will be a series that loses on the moneyline and wins on the +1.5 runline, so it's really a question of pick your poison.
