The Phillies just got back from a very disappointing trip (particularly for the offense) through Colorado and New York. They went 2-5, averaged just three runs per game, and got held to one run or less three times.
Last year, the Phillies were a vastly different team at home than on the road, going 49-32 at home with 370 runs scored and 104 home runs at home, and 31-50 with 307 runs with 82 homers on the road.
That trend has continued this year as well, as the team is now 8-5 at home and 5-7 on the road.
