OAKLAND -- Rookie starting pitcher Jarrod Parker has been so successful lately that it is almost a shock when he struggles on the mound. Entering the night, he had allowed one run or fewer in 10 of his first 14 starts -- matching a record dating back to 1918. On Saturday, he lasted just four and two-things innings, which is the second-shortest outing of his young career, and Seattle won the game 7-1. The loss snapped the A's five-game winning streak, and defeated Parker who had won his last three starts. "I made a lot of mistakes, I'm not happy with it," Parker said. "It's kind of embarrassing to be honest." Parker was pulled from the game with 94 pitches in the fifth inning. He allowed a career-high tying six runs -- five of which were earned. It seems Parker either pitches great or allows six runners to score. This is the third time he has allowed six runs in a game. All of his other starts he has allowed two runs or less. "We're so used to seeing him go out there and throw up zeros or one run or less," A's manager Bob Melvin said. "I thought his actual stuff was pretty good. It's just that his pitch count got up there rather quickly and he just started to fall off a little bit at the end." Parker got in trouble early in the game when he walked Michael Saunders in the first inning with two outs. Saunders ended up coming around to score when Coco Crisp missed a sliding catch on a ball hit to center field by John Jaso. He gave up a two-run double to Brendan Ryan in the second inning, and a solo homer to Casper Wells in the fourth. When Parker left the game in the fifth inning, two runners were on base. Jerry Blevins entered in relief, walked the first batter he faced, and then gave up a bases-clearing double to Kyle Seager. "What we want to do as a starting staff is be effective and attack early," Parker said. "I did the opposite tonight. It was not very good." A's starting pitchers hadn't allowed more than one earned run in their last seven starts. Parker snapped that streak. He will have to wait until July 15 to get back on the mound because of the All-Star break. "It's kind of just one of those nights," A's catcher Kurt Suzuki said. "He's been so good for so many starts you just kind of take things for granted." If there is a bright side to Parker's evening, it is that he was perfectly healthy, and had no issues mechanically. Good luck selling it to Parker that way though. "I felt good felt fine," he said. "It was execution that was terrible tonight." Notes:The A's only run came on a Josh Reddick home run in the first inning. It was Reddick's 20th homer of the season, making him the first A's player since Nick Swisher in 2006 to reach that mark before the All-Star break. "He really belongs and believes he is one of the elite right fielders in the league, and he has done nothing to disprove that at this point," Melvin said.Reddick also made a full extension diving catch in right field to rob Ichiro Suzuki of an extra-base hit. After Reddick put the A's on the board, Mariners starting pitcher Jason Vargas kept them off of it for the rest of the game. He tossed his sixth-career complete game and retired 13 batters in a row between the third and eighth innings. Vargas' last complete game was in July 6, 2011 against the A's. Travis Blackley threw three innings of scoreless relief on Saturday. Blackley had been bother by back soreness and had his turn skipped in the rotation as a result. The Australian-born lefty struck out three batters and only allowed one hit. An encouraging sign for the A's. "He's pitching really well," Melvin said. "He continues to impress for a guy that has a certain intensity and confidence now that he probably didn't have before the season."
OAKLAND -- Adam Rosales got counsel on leading off from Chris Young when they were Oakland teammates in 2013.
"He's like, just keep it the same, if not be more aggressive because it's either the first or second pitch of the ballgame is the best pitch you'll see that day," Rosales said. "Be ready."
When Ariel Miranda served up a splitter down the middle, Rosales pounced on the 1-1 pitch.
The A's two hottest hitters quickly got to Miranda (1-2). Rosales hit his first leadoff homer since May 3, 2013, then made his usual sprint around the bases.
"He brings a lot of energy to the table," A's manager Bob Melvin said.
The A's fed off that energy, and two batters later, Healy hit a two-run shot, his third this season and first since April 6.
Cotton (2-2) gave up two runs, six hits, two walks and hit a batter.
"I was talking to myself on the mound, saying `attack, attack, attack, stay convicted, no matter what,'" Cotton said.
Ryan Madson got four outs for his first save.
Miranda allowed four runs and seven hits in three-plus inning in his worst start of the season, failing to pitch at least five innings for the first time in three starts.
Rosales is 6 for 17 with two homers and a double during the A's win streak, and Healy is 9 for 17 over his last five games after going 6 for 40 in his previous 10.
The Mariners fell to 1-9 on the road. Their sputtering offense had nine hits Saturday, offering some encouragement to a team that's hitting .195 away from home.
"Sometimes you're good at home, sometimes you're bad on the road and sometimes you're good on the road and sometimes you're bad at home" said Robinson Cano, who hit his third homer. "It was the same way last year. We just have to keep fighting."
Seattle cut it to 4-3 on Kyle Seager's pinch-hit, RBI triple in the eighth. Seager, mired in a slump all month, came into the game batting .233 with no home runs in 60 at-bats and was 3 for 16 over his last five games.
Madson struck out Mitch Haniger swinging to end the game after Jarrod Dyson singled and stole second with two outs in the ninth.
The A's wore Golden State Warriors jerseys during batting practice on Saturday for a second straight day. The A's announced on Twitter that they plan to auction the jerseys with the proceeds going to charity.
Mariners: RHP Steve Cishek, who had offseason hip surgery, hasn't been sharp in two rehab appearances. "He's kind going through his spring training right now," manager Scott Servais said.
Athletics: CF Rajai Davis was out of the lineup for a second straight day with a hamstring injury. Manager Bob Melvin said he expects the speedster to be on the field soon and doesn't anticipate him going on the disabled list.
Mariners RHP Yovani Gallardo is winless through his first three starts. He's 0-5 with a 5.29 ERA in seven career starts against Oakland. ... RHP Andrew Triggs (3-0) is yet to allow an earned run through a team-record 17 2/3 innings. He gave up five runs and six hits in his only appearance against Seattle, a two-inning relief stint last year.
