Three days after participating in a match which yielded eight goals, Philadelphia hosted a scoreless stalemate against Portland.
The most entertainment the Timbers provided on the night was Jack Jewsbury getting into a shoving match with Union defender Sheanon Williams. No cards were issued for the incident.
Zac MacMath started his second consecutive game in place of the injured goalkeeper Faryd Mondragon. The 20-year-old kept a clean sheet, making an impressive block on Jorge Perlaza in the first half, a far cry from his poor showing Wednesday, when he conceded four times in half an hour.
"It was like night and day for me," MacMath said. "As a team it was definitely a big difference between my first and second game."
Union coach Peter Nowak praised MacMath's "good and stable performance" and claimed his side deserved the three points despite general weariness.
"It was a tough stretch for us, playing three games in one week," Nowak said. "You could see our guys cramping up."
Philly remains home next week, hosting the Columbus Crew. Portland will host the Revs.
