SEATTLE — Apparently somebody learned a few things during his time in Triple-A — but it wasn't Ervin Santana.

In a revival meeting between two right-handers trying to salvage horrid seasons (Santana and Jeff Weaver), Santana fled the scene quickly. The Angels pitcher retired just one of the first seven batters, putting the Angels in a five-run hole.

But Vladimir Guerrero drove in three runs with four hits and Kendry Morales (promoted from Triple-A on Friday) had three hits and drove in two runs — including the go-ahead run in the eighth inning, as the Angels shook off Santana's self-inflicted knockdown, climbed off the canvas and beat the Seattle Mariners, 10-6, on Tuesday night.

With victories in the first two games of this series, the Angels have doubled their lead in the American League West to four games over the second-place Mariners.

The Mariners aren't the only ones shrinking in the glare of the playoff-race spotlight. The more it recedes into the past, the more Santana's outstanding start in Boston 11 days ago seems like a mirage.

He coughed up a 3-0 lead in the middle innings of his next start (a 5-4 loss to Toronto last week) and turned in a performance that was hard for Angels manager Mike Scioscia to swallow Tuesday against the Mariners.

Scioscia pulled Santana while the game was still retrievable, replacing him with Dustin Moseley who had given up his spot in the starting rotation to Santana after his impressive return from Triple-A in Boston.

Moseley was everything Santana wasn't. He calmly rolled through the Mariners' lineup, pitching 513 shutout innings in relief as the Angels picked their way back into the game against Weaver.

The Simi Valley High graduate's season started even worse than Santana's. At the end of May, he was 0-6 with a 14.32 ERA.

When August started, he was 2-10. But he was on a four-start winning streak going into Tuesday's game.

That — and the five-run lead — began disappearing with an unearned run in the third and back-to-back home runs by Gary Matthews Jr. and Morales in the fourth.

The Angels chased Weaver and tied the score with two more runs in the fifth with a double by Jeff Mathis, an RBI single by Orlando Cabrera, a double off the center-field wall by Guerrero and a sacrifice fly by Garret Anderson.

They took the lead for the first time on Guerrero's RBI double in the seventh inning, but the Mariners matched that with a run off Justin Speier in the bottom of the inning.

In the top of the eighth, though, the Mariners' bullpen cracked. Brandon Morrow walked Matthews to start the inning and Matthews scored on Morales' double off the left-field wall. It was Morales' third hit in the game and his ninth in 19 at-bats since his latest recall from Triple-A last week.

After Brandon Morrow retired Howie Kendrick and Mathis, the Angels poured it on with two outs. Reggie Willits drew a walk and Cabrera singled to load the bases. Rick White replaced Morrow and broke Guerrero's bat with his first pitch. But Guerrero bounced a single into left field, driving in two more runs.

Another walk reloaded the bases and Maicer Izturis capped the four-run inning with an RBI single to right.
