SEATTLE | Sit yourself down for this little late-night bulletin from the Pacific Northwest: The Royals hit four home runs Thursday in an 8-4 victory over the Seattle Mariners at Safeco Field.</p><p> OK, sip the coffee and read that again.</p><p> The Royals hit four home runs Thursday night in an 8-4 victory over the Seattle Mariners at Safeco Field.</p><p> Yes, of course it was a season high. In fact, the Royals haven’t hit four homers in a game in more than 27 months. The muscle came from Brayan Peña, Yuniesky Betancourt, Alberto Callaspo and David DeJesus.</p><p> “We got a few squared up,” DeJesus said. “(Mark) Teahen should have had one, too. He squared up one better than anyone. He just hit it to the wrong part of the park.”</p><p> That came in the ninth inning on a drive that Seattle center fielder Franklin Gutierrez ran down at the outfield wall. No matter. Four were more than enough.</p><p> “The guys have been swinging the bats better,” Peña said. “The guys are still battling, and it was a great way to start the (seven-game) road trip.”</p><p> The Royals built a 3-0 lead against Seattle rookie Doug Fister on a two-run homer by Peña in the second inning and a solo drive by Betancourt in the fifth.</p><p> After the Mariners closed to 3-2 in their fifth, Fister yielded a two-run shot to Callaspo in the sixth inning. The three homers stuck Fister, 1-1, with a loss and a line that showed just five hits in six innings but also five runs.</p><p> “He was pretty good,” DeJesus said. “Really, he had good stuff. He just made a few too many mistakes.”</p><p> DeJesus extended the lead to 7-2 with a two-run homer in the seventh inning against reliever Shawn Kelley. The Royals’ only run not scored via a homer came on Josh Anderson’s two-out squib single in the ninth inning.</p><p> Royals starter Kyle Davies, 5-9, got the victory after limiting Seattle to two runs and five hits in six innings. Jamey Wright worked two scoreless innings before Bruce Chen served up a two-run homer to Jack Wilson in the ninth.</p><p> Chen then struck out the final three hitters.</p><p> The four-homer attack boosted the Royals to 49-78 and aided their efforts to avoid a fifth 100-loss season in eight years. Going 14-21 or better in their final 35 games will do it.</p><p> It was a strange ride for Davies: He wobbled through the first inning before working three strong frames. He then yielded two runs in the fifth and nearly didn’t make it through the sixth.</p><p> The Mariners put runners at second and third with one out in the sixth, but Davies wiggled free.</p><p> “I threw way too many pitches in the fifth,” Davies said, “then I go out in the sixth and walk the first guy &mdash; and I’m thinking, `Oh, man. Here we go again.’ But I made some really good pitches.”</p><p> DeJesus’ homer in the seventh seemed the finish Seattle and marked the Royals’ first four-homer game since May 23, 2007. That was an 11-7 victory over Cleveland at Kauffman Stadium and was so long ago that Cliff Lee had yet to become dominant.</p><p> Lee allowed three of those homers &mdash; to Mike Sweeney, Alex Gordon and John Buck. Mark Grudzielanek hit the fourth homer against Fernando Cabrera.</p><p> This latest binge came against the American League’s best staff: The Mariners entered the night with the league’s best ERA. Fister had a 2.21 ERA and quality starts in all three previous outings since entering the rotation.</p><p> Davies dodged a couple of bullets in the first inning. Gutierrez led off with a sharp drive into the left-center gap but was thrown out in trying to stretch a single into a double.
