It will be the first time for Meralco to win a championship in the All-Filipino Cup, and now that they are close to that, I'm sure they'll play harder in the next game (tomorrow) to finally get that win. As for the betting line, it's already available, and just like the previous game, SMB started at -3.5 and this could possibly move up to -5.5. Therefore, I believe now is the right time for bettors who think SMB will even the series. -3.5 should be easier to cover than -5.5.
Also, the total is now 185.5. I guess it will go under if Meralco wins, but over if SMB wins.
Something that will give them a decent credit beating both SMC teams though I still on the possibilities that SMB will push this and will try to have a do-or-die final game 7, not being bias as I really love SMB but with how Meralco controlling the tempo of the game, same with your assessments, if Meralco wins then chances to see an "Under" might take place while if SMB wins it might be the otherside, more on how the fans will react and how they will show supports to their chosen team, but for bettors more on studying how bookies place their odds and how they are playing with their offers.
