i Might just have found a flawless system in baseball please give me your opinion

[tech fan]

for the last 2 days i have picked the favorite by moneyline and the underdog +11/2.
On Saturday i had Yankees -300 Royals +11/2 yankees won by 1 I won both bets.
On Sunday I took San Diego Moneyline -170 and Colorado +11/2 Run line and won Both Bets.
In my opinion the worse you can do is split and if the Favorite wins by 1 you win both bets. Similar to buying the 1/2 a point when the line is 3 in football. You take 1 team -21/2 One team +21/2 If favorite wins by a Field goal you win both.

Is this good strategy or am i just getting lucky 2 days straight

Thanks for all your advice

if the fav loses @ -300

BET A NYY -300 $300 / $100

BET B KC +1.5 (+125) $100 / $125

KC WINS OUTRIGHT YOU LOSE $175

Coverboy, Kmann do this quite often and it pays off but only on low scoring games like 7.5 or UNDER
