The Rays play in a dome that blocks out the Florida sun - and the near daily thunderstorms - but can wreak havoc with rookies.
Catcher Adam Moore shagged fly balls in early batting practice and kept losing them in the ceiling.
What about foul pop ups?
"Man, I have no idea," he said. "I guess you look up, and if you don't see it, you call 'Yours!' and hope the first or third baseman can save you.'"
Moore isn't catching tonight - Kenji Johjima is - and the Mariners start this game with a better record than Tampa Bay, the defending American League champions.
Seattle is lookiing for it's 79th win. It's Ryan Rowland-Smith vs. Jeff Niemann.
Hit it like a man!
Rowland-Smith is having one of those innings alll pitchers have and hate. He's given up one well-hit ball and some rather unlucky hits.
Willy Aybar doubled on a soft opposite field line drive and B.J. Upton singled him home. Fernando Perez singled into a center - an excuse-me blooper - and Jason Bartlett hit a one-hopper off Rowland-Smith that loaded the bases.
He got out of it with little damage, but it wasn't fun and it took a lot of pitches.
After two: Rays 1, Mariners 0
Just hit it
Neimann hasn't won 12 games by accident, and when Franklin Gutierrez led off the fourth inning with a single, it was just Seattle's second of the game.
Gutierrez has them both.
Jose Lopez grounded into a double play in the first, Johjima did the same in the second.
With Griffey at the plate, Gutirerrez stole second base - his 15th stolen base of he season. Junior grounded out, sending Gutierrez to third base with two out.
Adrian Beltre's soft single to center field scored him. That's a manufactured run, folks.
In the fourth: Mariners 1, Rays 1
Ichiro, home run hitter
For folks who have wondered what Ichiro might look like if he consciously tried to hit more home runs, consider this game.
In his first two at-bats, Ichiro looked like a man trying to pull the ball and grounded out and popped up.
In his third at-bat, he hit his 11th home run of the season - a two-run shot with Mike Carp aboard.
In the fifth: Mariners 3, Rays 1
A fading starter
All those second-inning pitches under duress seem to have caught up with Rowland-Smith in the sixth.
He walked the first man he faced, then gave up a double to Aybar to put men at second and third base with no one out.
When he walked Dionne Navarro with his 114th pitch to load 'em up, Shawn Kelley trotted in to relieve. Yes, the same Kelley who'd allowed a pair of grand slams this season.
B.J. Upton singled home one run. With one out, Bartlett flied out to push home a second run.
After six: Mariners 3, Rays 3
Setup man Dan Wheeler pitching, and with one out Jose Lopez went deep - his 25th home run of the season.
In the eighth: Mariners 4, Rays 3
And in the ninth
Miguel Batista went two strong innings, and for those wondering why, consider this: Seattle is without David Aardsma tonight.
Not sure why, but because he was running before the game, best guess is stiff arm or shoulder.
Without Aardsma, the ninth went to Mark Lowe. Carl Crawford walked, although two pitches called balls appeared to be thrown through the heart of the strike zone.
Bartlett popped out.
With Crawford running - going after his 60th stolen base - Gabe Kapler popped out, so Crawford had to sprint back to first. Evan Longoria struck out.
That's 79 wins with 11 to play. A year ago, the Mariners had 57 wins at this point.
It's a final: Mariners 4, Rays 3
