The team with Home Field in the LCS (call them the favorite) wins game 1 (over the underdog), but loses Game 2.
Traveling to the other city, the favorite loses both Games 3 and 4 on the road but has their ace going in Game 5 against the other team's left handed Game 1 starter, with a matchup against arguably the underdog team's best pitcher, a young RHP, in Game 6 looming, but back at home.
The favorite takes a 2-1 lead in the top of the 3rd inning of Game 5 and holds it for a few innings.
