ANAHEIM, Calif. -- Logan Morrison hit a go-ahead RBI double during Seattle's two-run 12th inning, and the Mariners hung on to beat the Los Angeles Angels 3-2 on Saturday night.
The AL West rivals played extra innings for the second straight night, less than 24 hours after the Angels won the series opener 3-2 in 16 innings.
Los Angeles remained 1 1-2 games behind AL West-leading Oakland.
Joe Thatcher (0-1) gave up a leadoff double in the 12th to Kyle Seager before Morrison drove him in with a hit down the left field line. Pinch-hitter Justin Smoak drove in pinch-runner Willie Bloomquist with an infield hit.
Dominic Leone (3-2) pitched one-plus inning for the victory after taking the loss Friday. Leone was pulled after he gave up a leadoff homer to David Freese.
Charlie Furbush got three outs for his first save in four major league seasons.
Howie Kendrick legged out a leadoff double in the Angels' ninth after his line drive ticked off the glove of shortstop Brad Miller and into short left field. But Brandon Maurer struck out Freese and retired Efren Navarro on a popup before Chris Iannetta struck out for the fourth straight time.
Five-time All-Star Felix Hernandez yielded an unearned run and just two hits in seven innings with nine strikeouts and four walks. This was the 12th consecutive start in which the 2010 AL Cy Young Award winner threw at least seven innings and allowed two runs or fewer.
The Angels' only hit against Hernandez through the first six innings was a leadoff double to left-centre in the fourth by All-Star MVP Mike Trout. The right-hander, who started for the AL in the All-Star game, took a 1-0 lead into the seventh and walked Albert Pujols and Josh Hamilton with none out before giving up the tying run.
Miller made a diving stop of Kendrick's single behind second base and threw wildly past first base, allowing Pujols to score. Hernandez minimized the damage by fanning Iannetta with runners at second and third. Iannetta is 2 for 20 lifetime against Hernandez.
Garrett Richards, who came in with the same 11-2 record as Hernandez, allowed a run and three hits in eight innings and struck out seven. The right-hander retired his first 15 batters on just 49 pitches and struck out the side in the fourth before giving up a leadoff double in the sixth to Dustin Ackley and a line-drive RBI single by No. 9 hitter Jesus Sucre.
NOTES: Hernandez has allowed only two home runs to the last 456 batters he has faced over his last 16 starts and 118 2-3 innings. ... Huston Street pitched a scoreless ninth in his Angels debut following a trade Friday with the San Diego Padres. He became the Angels' 29th pitcher this season, tying the franchise record set in 1996. The Angels made room for Street on the active roster by optioning 1B/DH C.J. Cron to Triple-A Salt Lake. ... Angels SS Erick Aybar sat out because of soreness in his groin, which forced him out of Friday's game. ... Hamilton again was done in by Seattle's over-shifted infield as 2B baseman Robinson Cano threw him out from the outfield grass his first two times up.
