Yes, we do. But Cora was smart in resting our players and keeping them healthy, over worrying about clinching HFA. If you can have both, then even better.
That said, while you want to have a Game 5 or a Game 7 in your home park, if the visiting team wins just 1 of the first 2 games, then "HFA" shifts to the away team, and it might be Game 4 or Game 5 that is the clincher. There are times that I really feel like I'd rather start a series on the road, especially in the ALDS.
