PHILADELPHIA (AP) — The Philadelphia Phillies find themselves in a new role this postseason.The two-time defending NL champions are no strangers to big games, having advanced this far in three straight years. The only difference between now and the last two trips to the league championship series is the Phillies are the favorites to win it all this time, thanks in large part to the three proven aces in their pitching rotation.It’s World Series or bust in Philadelphia. Nothing less is acceptable in a city that’s become spoiled by its baseball team’s success.Who would’ve thought the losingest franchise in pro sports would reach the point where it’s the one other teams hope to emulate?The Phillies are trying to become the first NL club in 66 years to win three consecutive pennants, and they’re going for their second World Series title in three years.“It’s a good challenge for you.
