I would take them moneyline, because it still gives you a chance to win both bets, and would rather get plus odds on semi hedge. I have the dodgers in 6 on a prop bet, and took TB on the moneyline tonight. I can't win them both but I locked in a profit, and if TB wins tonight, I'll be on LA in game 7. Good luck either way.
I always look at the vig when looking at runlines. Most of the time you are paying more vig on a RL than on ML because of the reduced juice. The only time you might get less vig on a RL is if it's a huge favorite, which is not the case tonight. Your call though.
