No, not just because of the weather, which has closed the roof at Safeco Field.
Look at Seattle's starting lineup or its roster, and it's like looking at a gaggle of kids just brought up from the minor leagues.
The bottom third of Seattle's lineup vs. New York tonight is Jack Hannahan, Josh Wilson and Michael Saunders - none was with the team before the All-Star break.
Add in the starting pitcher, Ian Snell, and Luke French and Doug Fister ... you get the picture.
Tonight, Snell and a bullpen a bit short because of the 14-inning game Wednesday take on the team with the American League's best record - though tonight, Alex Rodriguez is not in the Yankees lineup.
Feel free to insert your own A-Rod joke here.
It's C.C. Sabathia vs. Snell, and a Mariners victory would match their win total of 2008.
Yanks strike first
Hideki Matsui singled and Nick Swisher walked on four pitches before Robinson Cano flied out.
Snell got a second fly ball, this one hit shallow to Ichiro, and the runners couldn't advance.
Jerry Hairston was jammed and blooped one toward center field where Franklin Gutierrez momentarily froze, then dove and had the ball kick off his glove and toward left field - an RBI double.
Snell's wild pitch eluded Johjima as Swisher scored. Jose Molina struck out.
In the second: Yankees 2, Mariners 0
Yanks strike again
On the first pitch of the third inning, Derek Jeter hit his 14th home run. Johnny Damon doubled and took third on a ground out.
Hideki Matsui hit his 18th home run.
With two outs, Robinson Cano singled and Melky Cabrerera walked on Snell's 56th pitch.
He's throwing hard - 93 to 95 mph with the fastball - but being hit just as hard.
In the third: Yankees 5, Mariners 0
Um, more Yanks!
Snell can't quite get through a clean inning, and New York has all but put the game away.
With one out, Jeter singled. With two outs, Teixeira doubled him home.
Snell has to eat some innings, and has thrown 67 pitches through four. With the bullpen a bit chewed up, it's probably Snell and Miguel Batista.
In the fourth: Yankees 6, Mainers 0
There's a surprise!
Josh Wilson, the utility middle infielder picked up by Jack Zduriencik on waivers, hit his first American League home run in the fifth against Sabathia - just the Mariners second hit.
It's the Mariners second run in 19 innings.
After five: Yankees 6, Mariners 1
Goodnight, Mr. Snell
It won't go down as his favorite start of the season, but Snell got the Mariners into the seventh inning before he ran out of steam - and command.
Damon doubled, again, and Teixeira walked on Snell's 109th pitch of the night. That was enough for manager Don Wakamatsu, who brought in not Batista but left-hander Garrett Olson.
Matsui singled home Damon with New York's seventh run and, given the fact that Mariners are averaging one run every 10 innings the last two nights - and have just two hits tonight - the suspense seems to have left Safeco Field tonight.
Both of Snell's runners scored after he departed, so he's on the hook for the loss and eight earned runs.
In the seventh: Yankees 9, Mariners 1
Yanks - yawn! - strike again
Matsui connnected for his second home run of the night and 19th of the year.
In the eighth: Yankees 11, Mariners 1
