Are the commas correct around "and win" as shown below? If they make it to, and win, the fourth game, are they in the World Series?
I vote yes; forgive my lack of evidence, for, as I was once told, a physicist can explain hitting a ball out of the park, but likely cannot do so, and vice versa.
No commas at all. They need to BOTH make it to AND win the fourth game. If they do this are they in the final?
To make it to game four implies the unfinished instance of at least game three, which means they will make it to game four regardless. As @Shadowfax points out, there is a possibility OP means two questions or just one. Edit: If they win the first four games (of the National or American League finals), will they be in the World Series final?
