Not many things have gone wrong for these Phillies lately.

Nearly all of the sins of their atrocious first half have been forgiven. They're getting timely hits. They eke out close games. Their bullpen, problem No. 1 in the first half, has looked strong.

Their early season transgressions have not evaporated, though. The Phillies are still paying for it in the form of pressure, as they have to be near perfect the rest of the season if they want to snatch the second wild card spot in the NL playoff race. Usually a series with the worst team in baseball is a time to relax; this weekend's four-game set in Houston represents the most important games of Philadelphia's season.
