The Philadelphia Phillies have constructed quite a legacy these past few autumns, one that includes, so far, two straight NL pennants and the 2008 World Series title. And it is a legacy that is very much on the line at Citizens Bank Park this weekend.  Beat the San Francisco Giants twice more, in Games 6 and 7 on Saturday and Sunday, and the Phillies can make history - as the first NL team in more than 60 years to win three straight pennants. Lose one of those games, and the Phillies' season is over - their legacy, if not exactly diminished, not quite enhanced, either.  "We've got a good chance now to win, because of who we got pitching and because we're home," Phillies Manager Charlie Manuel said Friday, less than 24 hours after his team survived Game 5 in San Francisco and sent the series back to Philadelphia. "That gives us a little advantage. But then we've got to win."  This was a team constructed to win the World Series; the Phillies' management spared almost no expense to build it. They acquired one of the best, and best-paid, pitchers in baseball over the winter - Halladay - then acquired his statistical near-twin, Roy Oswalt, seven months later. In between, they handed over a $125 million contract extension to their biggest star, slugging first baseman Ryan Howard.  In a sense, the Phillies' season comes down to that trio, the Phillies' three highest-paid players. Oswalt gets the ball in Saturday's Game 6, six days after beating the Giants in Game 2, and three days after an 18-pitch relief appearance in the Phillies' Game 4 loss.  "I try to pitch every game like it's the last one," Oswalt said. "You're never guaranteed the next day. It's a must-win game, but I treat every one of them like a must-win."  Howard, who has averaged 136 RBI per season over the last five years, is still looking to drive in his first run of this series, and he has been particularly helpless against left-handed pitchers this postseason (3 for 13 with eight strikeouts) - which is significant because the Phillies will be facing Giants lefty Jonathan Sanchez in Game 6.  "When we get guys on base, I think he's definitely trying too hard," Manuel said of Howard. "He's thinking about knocking runs in and things like that. I think he needs to slow down and just hit a couple of balls good and things will happen for him."  And finally, there is Halladay. His first season in Philadelphia has been an unmitigated success, with a perfect game in May, the no-hitter against Cincinnati in the NL Division Series and, almost certainly, a Cy Young Award awaiting him in November. But he was beaten in Game 1 of this series, and had to survive a strained groin and a resulting drop in velocity and effectiveness to pull out the win in Game 5 that kept the Phillies' season alive.  As Halladay threw in the outfield Friday afternoon, he was watched closely by Phillies pitching coach Rich Dubee - who was wearing street clothes, as the team didn't arrive in Philadelphia until around 6 o'clock that morning and did not work out as a team Friday - and by a member of the team's training staff.  Halladay has already informed the Phillies he is fine to start in the World Series, should they survive and advance, but the Phillies also are interested to know whether Halladay could pitch in relief of starter Cole Hamels in Game 7, if there is a Game 7.  "From the first day he's been with us, you find out something about him every day that tells you how he can do [what he does], and why he can do it," Manuel said of Halladay. "He fought and he battled [in Game 5], and he got us to a pretty good place in the game. That definitely shows what type of person he is."  Over the last few years, it has become clear there is a type of player the Phillies covet. Second baseman Chase Utley may be the prototype, but of late the Phillies' clubhouse is filled with them. They play (or pitch) hard. They are strong of character. They are more introverted than extroverted. They are good teammates, bad interviews. They are also, of course, immensely talented.  And above all, they never surrender, not even when they are down three games to one in the NLCS and preparing to face the league's two-time defending Cy Young winner, as the Phillies were Thursday in going up against San Francisco's Tim Lincecum in Game 5.  "They know they're going to play tomorrow or next year. They know they've got a lot of baseball left," Manuel said of his players. "But at the same time they know - today is the day that we're supposed to shine. When you talk about playing in the moment - that is the moment. That's the philosophy we have."  Manuel mentioned Halladay and Oswalt by name - two pitchers who weren't here when the Phillies won it all in 2008, or when they lost the World Series to the New York Yankees in 2009, but who seem so ingrained in the Phillies' culture now, it is as if they were here all along.  "Those guys, when they came in here," Manuel said. "They're right on course with us. They fit right in perfect with us."
PHILADELPHIA -  In an empty stadium late Friday afternoon, Roy Halladay, in blue shorts and a Phillies-red pullover, played catch in the right field grass, not far from the spot where Jimmy Rollins's memorable game-winning double landed in the ninth inning of Game 4 of the 2009 National League Ch...
