DETROIT -- A Mariners team fighting through some early challenges took on a couple more Wednesday when ace right-hander Felix Hernandez and standout rookie right fielder Mitch Haniger were placed on the 10-day disabled list amid a flurry of roster moves, as the club brought in reinforcements.
The two were both removed in the third inning of Tuesday's 19-9 loss to the Tigers and evaluated by the team's medical staff Wednesday. They were scheduled to fly back to Seattle on Wednesday night for further tests from team doctor Ed Khalfayan on Thursday.
"Obviously the start Haniger is off to has opened a lot of eyes, not just in our clubhouse, but around baseball," manager Scott Servais said. "And everyone knows what Felix means and being able to run him out there every fifth day and taking innings and getting us deep into games and giving us a chance to win.
"It is a bit of a blow. But it's part of being a pro. You come to work the next day and try to get yourself in a good spot to help the team win a ballgame tonight and that's where we need to focus."

Outfielder Ben Gamel and pitchers Chase De Jong, Dillon Overton and Casey Fien were recalled from Triple-A Tacoma, while pitchers Evan Marshall and Chris Heston were optioned back to Tacoma.
De Jong, a 23-year-old right-hander, will get his first Major League start in Hernandez's place on Sunday in Cleveland in the final game of Seattle's 10-game road trip.
Hernandez, a six-time All-Star, is 2-2 with a 4.73 ERA in five starts this season after allowing four runs on six hits in his abbreviated outing against Detroit.
A source has told MLB.com's Jon Paul Morosi that Hernandez is expected to be sidelined at least two to three weeks.
It's only the fourth time the 31-year-old has been placed on the disabled list during his 13-year Major League career and just the second since 2008. He missed seven weeks last year with a strained calf muscle.
Hernandez left after Tuesday's start without talking to reporters and again declined to comment in the clubhouse before Wednesday's game.

Servais said Hernandez struggled warming up Tuesday, but there were no real concerns until his arm appeared fatigued in the second inning.
"Often pitchers will say their routine between starts, they don't feel great or are a little soggy, whatever terms you want to use," Servais said. "He didn't feel great warming up, but that happens a lot, then guys go out and give you five, six, seven innings and a great outing.
"But he went out for the second inning and just felt dead. No sharp pain or anything like that, just the ball wasn't coming out and he didn't feel good and he certainly didn't look good. We'll have the doctors evaluate him and see where we're at."
Servais said he won't have any time estimates on either Hernandez or Haniger until they get further tests in Seattle, but acknowledged Haniger will likely be out two to three weeks and possibly longer since oblique injuries can be nagging.
Entering play Wednesday, Haniger was hitting .338 and led the American League in runs (20), was second in on-base percentage (.442), tied for third in hits (27) and doubles (seven), fourth in extra-base hits (12) and tied for fifth in RBIs (16).
Gamel, who was hitting .288 with a .419 on-base percentage in 59 at-bats for Tacoma, will help bolster the outfield after center fielder Leonys Martin was designated for assignment in a surprising move Sunday. Gamel got the start in right field for Wednesday's game against the Tigers.
