Oakland established an American League record Monday night, and not one the A's were celebrating with pies or leans. The A's dropped their ninth straight season opener, breaking the AL mark they had shared with the 1963-70 Washington Senators and tying the major-league mark held by the 1972-80 Braves and the 1893-1901 New York Giants. The A's know this drill: Four Opening Nights in a row and five times in the past seven openers they have had to face Seattle's Felix Hernandez. The 2010 Cy Young winner retired the first 10 batters he faced in the Mariners' 2-0 win at the Coliseum, and he improved to 4-0 lifetime on Opening Day, three of those against Oakland. "He's a tremendous pitcher, obviously," A's starter Brett Anderson said. Referring to Hernandez's new contract, he added, "$175 million worth." The A's did threaten enough in the eighth to chase Hernandez, who exited with two on and two outs. Left-hander Charlie Furbush walked Coco Crisp, creating visions all over the Coliseum of the A's late-inning dramatics in 2012, but pinch-hitter Derek Norris grounded into a forceout against right-hander Stephen Pryor. In five Opening Day starts against Oakland, Hernandez has allowed six runs in 39 1/3 innings, with 35 strikeouts. "It is a bit redundant to see him as often as we do," A's manager Bob Melvin said.
