OAKLAND -- Bartolo Colon went down, Tommy Milone came up, and the A's won on Sunday.
No big deal, no commotion, it's just the A's these days.
Deep, dangerous and unflappable. They're not a perfect team, but they're definitely not sensitive to changes on the fly, and they can't be.
"This sounds worse than I mean it, but we lost Bartolo last year (to a suspension) and we brought somebody up that filled his space," catcher Derek Norris said after the A's 7-3 victory over Cleveland at the Coliseum.
"He may be only gone for a couple weeks. But the great thing about this team is when someone goes down we have the ability to bring somebody up and do a great job.
"That's what makes a very deep team and it makes us a very good team as well."
Of course, there are no guarantees that, amid all the changes, the A's will chase down the Rangers in the A.L. West (they're currently a half-game behind) or win an A.L. wild-card spot (they currently have one of the spots).
But the A's won't be completely derailed by roster emergencies, that's for sure; they've already suffered more than a few, and they absolutely will be dealt several more.
Milone, summoned back from a recent demotion after Colon went to the disabled list, lasted only two outs into the fifth inning Sunday.
But overall, Milone's stuff was good, and he kept the A's in the game -- he'll have to be just as good or better for at least a couple more starts.
It's just part of the A's enviable starting depth; they planned for blips and adjustments like this. Now it's mid-August, and they have extra arms lying around for key starts.
Colon -- their ace for most of the season -- struggled for a few starts, hit the D.L., and there's an established veteran lefty ready.
Nothing set in stone for the A's, ever.
"It's our only choice, right?" said shortstop Jed Lowrie. "We're fortunate they've got a few guys we can bring up.
"And we still have Brett Anderson on the D.L. It's a pitching-rich organization. They focus on it. And that's what we're going to need to win."
Oh yeah, Anderson. The talented, oft-injured left-hander is coming back from a long D.L. stint and might be ready to jump back into the A's rotation after one more rehab start.
More than anybody on this roster, Anderson is the wildest A's wild card: He's a front-line starter in reserve, waiting for his turn -- if he's healthy.
"I think the thing that's most important is we don't want to waste his bullets on rehab assignments," manager Bob Melvin said of Anderson.
"We want to get him to the big leagues as soon as he can."
That's another echo from last year, when Anderson emerged from a long D.L. stint to go 4-2 in the final weeks of the season and won Game 3 of the ALDS against Detroit.
Even if Colon comes back as soon as possible (which would be early September) or if Milone goes lights out in Colon's spot, the A's still might need Anderson into October.
That's because rookie sensation Sonny Gray has never been in a pennant race before, and because he is pushing close to a probable innings limit.
Gray, who threw 152 innings last year in the minors, has pitched 1361/3 innings so far this year in the majors and minors combined.
He probably could safely go another 50 to 55 innings, but maybe not a lot more, which means the A's have to start thinking about scaling him back.
"As I sit here right now, I'm not thinking about it," Melvin said of a Gray innings limit. "I mean, maybe it comes to a point where you have to look at that.
"But we do have some depth in the rotation, too. If we had to do something like that, we could probably maneuver around it."
Again, I'm sure this is all part of a larger A's plan -- or plans -- as general manager Billy Beane and Melvin go through all their late-season options.
They could go with Milone and Gray in the rotation for another few turns, then get Anderson ready for one of those slots and then Colon after that.
They could alternate all four in those two slots -- building around Jarrod Parker, A.J. Griffin and Dan Straily.
And if the A's get into the postseason, they could pick and choose from any of those seven options.
There's no surefire ace in that group. Things might not work out if the A's hitters don't rev it up a little, too.
But the A's won't be stuck without options; they built that into this season; they planned for the un-plannable.
Now it is happening, and they're so deep and so prepared they barely notice.
