OAKLAND -- The A's, who ended spring training as one of the hottest-hitting teams in the desert, are the early leaders in major league baseball's tundra division.

For a second consecutive night, the Oakland bats remained paralyzingly cold in a 7-1 loss to Seattle. The A's scratched out just three hits and a walk against Hisashi Iwakuma and a crop of Mariners relievers Tuesday as Oakland fell to 0-2.

Batting coach Chili Davis said he's not worried, but he'd like to see better results than he's seeing from an offense that went 8-1-1 in the final 10 games of the spring.

"You have to give their pitchers some credit, particularly Felix (Hernandez) last night,'' Davis said. "But I hate to give pitchers credit. We came out of spring training relaxed and hitting well, and things looked good.

"We look like we're trying to get more out of our at-bats up here, and as a result, our production isn't where it needs to be.''

The A's got their first and only run of the first two games in the second inning when left fielder Yoenis Cespedes homered. From that point on, the A's got just three base runners.

"We've got to just file this game away,'' first baseman Brandon Moss said. Moss was 0 for 3 and is hitless in seven at-bats the first two games.

"We're not getting what we're used to,'' Moss said, "quality at-bat after quality at-bat after quality at-bat. We came in relaxed, but now we're almost pressing instead of playing loose. We've got to try to get it together. Things can't be much worse than they were tonight.''

That was true for the pitcher in green-and-gold as well. Starter Jarrod Parker, who had an off-kilter spring (0-2, 7.45 ERA) gave up five hits, three walks and four runs in a five-inning start. One of the hits was a three-run bomb by Mike Morse, one of two homers on the night by the Seattle outfielder, and that turned a 1-0 A's lead into a 3-1 Seattle advantage in the third inning. Oakland was never really in the game after that.

"I never really settled in,'' Parker said. "I never got comfortable. I didn't have an out pitch to turn to.''

Oakland manager Bob Melvin watched Parker struggle from the outset. The right-hander exited the game in the fifth inning, just after Kyle Seager's double and Kendrys Morales' single gave Seattle a three-run edge.

Iwakuma wasn't as dominant as Hernandez was the evening before, but he was much more than the A's could handle. He allowed just two men to reach base in the first six innings, Cespedes with his first homer opening the second and Eric Sogard with a one-out single to left in the third.

Melvin said that with the offense floundering, it was going to be difficult to win, no matter which pitcher he started.

"We got what? Three hits tonight,'' Melvin said. "Combine that with walking (eight Mariners), that's not a recipe to win games.''

  • Bartolo Colon gets his first start Saturday for the A's in Houston in Game 6 of the season. He is still serving the final five games of his 2012 suspension for the use of performance-enhancing drugs.

    "You want to get him started sooner rather than later,'' Melvin said. "We would have had to find another place for him to pitch (to keep him on schedule), and we just wanted to get him in there.''

    Colon's last start before the suspension was Aug. 18.

  • Two disabled infielders, Adam Rosales and Hiro Nakajima, worked out with the A's pre-game, but Nakajima came off the field after a workout of perhaps a dozen minutes. Rosales (left ribs) is eligible to come back April 10 and Nakajima (left hamstring) on April 11. Nakajima is perhaps closest to returning. Melvin said the shortstop could travel with the team Thursday to Houston if he showed he was close to being ready.

  • Closer Grant Balfour, who had knee surgery just a couple of days into spring training, got into the game, but he wasn't sharp and gave up a homer to Morse and a double to Franklin Gutierrez, the first two men he faced.

  • Designated hitter Seth Smith was still marveling at the performance turned in by Hernandez on Monday in a 2-0 Seattle win.

    "He was better than I remember him from last year. He's something else.''
