CHESTER, Pa. — Roy Miller began playing in MLS the same year as the Philadelphia Union.

Seven years and 130 games later, Miller finally delivered his first MLS goal — and it was a big one as it proved to be the game-winner in the Portland Timbers’ 3-1 victory over the sputtering Union on Saturday.

“It’s good, I’m happy,” Miller told “I’ve never scored in MLS and today was the moment. But the more important thing is we got the three points, and I’m helping the team get those three points.”

Miller has certainly been a valuable contributor in his first season in Portland, filling in for injured captain Liam Ridgewell over the last five games and providing veteran leadership along the backline for the surging Timbers (4-1-1).

And that’s exactly what Portland coach Caleb Porter thought the 32-year-old center back was capable of when the Timbers signed him via a transfer from Costa Rican club Saprissa in January. Before that, the Costa Rican native played six seasons for the New York Red Bulls.

“We thought this was a guy that could be a great center back for us," said Porter. "We thought he’d be a cover guy, but Ridgewell has been out for the last five games, our best defender and our captain. So, that’s why we signed him, to be able to step in. He's been really solid.”

Of course, any kind of offense from Miller is simply a bonus for the Timbers. But on Saturday, the 6-foot-2 center back rose up to flick a perfectly placed Diego Valeri free kick, which then hit off Union defender Richie Marquez’s head and into the net.

The 66th-minute goal, which came after Darlington Nagbeopened his own account on the season, broke a 1-1 tie and sent the Timbers well on their way to the fourth win of the season.

“Diego kicked a good [free-kick] and I just tried to get to the end,” Miller said. “Marquez touched it a little bit. It was good the ball went in — and then we just celebrate.”

The Timbers have been doing a lot of celebrating so far this season, and Miller — who said he’s happy to be at center back after playing a lot of left back in New York — is one big reason why.
