Action points in baseball involve betting how many runs a team will win by. You still use the money line to calculate risk/payoff.
For example:
Today the line on STL SFO is
STL +115
SFO -135
If a player takes action points ($100 per point) on SFO and SFO LOSES by 2 runs (i.e. 5-3 or 7-5) Then the player loses 2*100*1.35 ($270)
The cap/limit will depend on your aversion to risk or bankroll if you're a player. A three run cap is OK.
