PHILADELPHIA (CBS) – Game One was historic. But tonight the Phillies turn the page and play Game Two of their National League Division Series against the Reds.

Phillies fans may want to relive and savor Roy Halladay’s epic no-hitter in the series opener. But Phillies GM Ruben Amaro Jr. says that’s just one win and they need three to move on:

“Momentum can be created and lost from game to game and inning to inning. So in our minds, there’s a lot of work yet to do. This is still the best offensive team in baseball we’re playing against, or one of them.”

MLB Network baseball analyst Ken Rosenthal also has an opinion on momentum:

“In baseball, the phrase is, ‘Momentum is the next day’s starting pitcher.’ What Roy Halladay accomplished really doesn’t mean much. And the fact that there’s a day off between games probably makes that more true.”

Rosenthall says starting pitchers Bronson Arroyo and Roy Oswalt will be the key in Game Two:

“The Reds were the top offensive team in the National League this year — believe it or not! And Oswalt, as good as he’s been in this park in particular, is still going to need to pitch really well to beat them.”

But history is on Oswalt’s side — he’s 23-3 with a 2.81 ERA in his career against the Reds. First pitch is scheduled for 6:07 p.m.
