OAKLAND, Calif. -- Winning a franchise-best 22 spring training games is one thing. The Seattle Mariners are doing it in games that count, against the defending division champions.
Michael Morse hit a three-run homer and a solo shot, Hisashi Iwakuma followed up Felix Hernandez's gem with an impressive outing of his own, and Seattle beat the Oakland Athletics 7-1 on Tuesday night.
Iwakuma (1-0) struck out seven and didn't walk a batter as the Mariners won their second consecutive game against Oakland to begin the season. He gave up a leadoff homer by Yoenis Cespedes to the deepest part of center field in the second inning, then quickly regrouped and retired 15 of his final 16 hitters.
Kyle Seager doubled twice among his three hits, drove in a run, scored a pair and reached base five times. Kendrys Morales added an RBI single for Seattle, which is 2-0 for the eighth time in club history.
"Definitely a good day," Seager said. "A good day for a lot of us."
After King Felix and three relievers combined on the third Opening Day shutout in Mariners history Monday, Iwakuma did his part against the reigning American League West champions.
So did the hitters.
Morse, a former Mariners farmhand who returned to the franchise this season, had his sixth career two-homer game and first since Sept. 27 last year with Washington at Philadelphia.
"Guys are confident up there," Morse said. "We had a good spring, and guys are carrying it over. ... We're just playing with our blinders on. Keep pushing."
Seattle tagged Jarrod Parker (0-1) for four runs and five hits in five innings, working the count to raise his pitch total in a hurry. The right-hander, a 13-game winner last season as a rookie, walked three and struck out one. He led the A's pitching staff with 63 free passes last season.
Parker allowed consecutive singles to Michael Saunders and Seager to start the game but retired Morales on a popup and induced Morse's inning-ending double play. The pitcher also worked through the second unscathed before allowing back-to-back walks to Saunders and Seager in the third. Morales reached on a fielder's choice, and Morse then sent a 2-2 pitch the other way to right. Josh Reddick slammed face-first into the fence trying to make a play.
Justin Smoak drew a bases-loaded walk as Seattle added a run in the seventh against Ryan Cook, who had a pair of four-pitch walks and a five-pitch free pass to go with a hit batter in a rough seventh. Oakland walked eight in all.
"We put up some tough ABs tonight," Seattle manager Eric Wedge said. "When you do that, good things will happen."
After almost daily lineup changes last year, A's manager Bob Melvin stuck with the same hitters in order for Game 2. The group held to three hits in a 2-0 loss to Hernandez a night earlier mustered just three more.
"Well, what'd we get, three hits today? That's not going to win you many games," Melvin said. "Then we walked seven or eight or whatever it was, so that's not a great recipe to win the game. It was a bad game for us today."
Iwakuma got through a 1-2-3 first inning on 10 pitches and was unfazed after Cespedes connected. The pitcher, who posted a club rookie record 2.65 ERA in 16 starts last year, allowed two hits in six innings. He would have stayed in the game had the blister on the middle finger of his pitching hand not become "a little tender."
"After that home run, I said, 'I need to stay calm and be patient,'" Iwakuma said through a translator. "That got me in a groove."
Next Friday night at Safeco Field, he will oppose pal Yu Darvish, who came oh-so-close to a perfect game for the Rangers at Houston on Tuesday. Iwakuma found out during his outing that Darvish's bid had been broken up with two outs in the ninth.
"You're always proud," Iwakuma said.
Raul Ibanez, whose late-game power during the playoffs last fall lifted the Yankees, earned a start in left field as he returns to the Mariners for the first time in five years since spending the 2004-08 seasons with Seattle.
A's reliever Pat Neshek received warm applause when he entered in the sixth. Oakland's players and fans rallied around Neshek after his newborn son, Gehrig, died 23 hours after his birth just before the playoffs began last fall.
Oakland RHP Bartolo Colon will make his first start Saturday at Houston since receiving a 50-game suspension for a positive testosterone test last Aug. 22. That means Parker, Tommy Milone and A.J. Griffin each will get two extra days of rest and No. 1 starter Brett Anderson one additional day with the team off Monday. ... Injured A's SS Hiroyuki Nakajima, who began the season on the disabled list with a strained left hamstring, had a short workout on the field. ... By losing Monday night, Oakland's skid on Opening Day reached nine games -- setting an AL record and matching the major league mark shared with the New York Giants (1893-1901). ... Seattle plays 14 straight games before its first off day. ... LHP Joe Saunders makes his season debut for Seattle on Wednesday night against Milone.
