It was a perfect storm of rain and runs Tuesday night in Fenway Park, with the A's taking a weather-shortened 13-0 win over the Red Sox behind starter Bartolo Colon.

And it came at close to a perfect time for the A's, who had lost four games in succession before finding wind and rain to their liking almost from first pitch to last.

Colon was by far the most comfortable looking man in uniform on either side. He was the only Athletics player not dressed up as if he were skiing the Alps. He just threw fastball strike after fastball strike all night.

"I don't like to wear sleeves," Colon said through interpreter Ariel Prieto in explaining his back-to-the-tropics look on a night where there wasn't a square centimeter of dry space at Fenway. "All of my career it's like this. No sleeves. Except in the dugout. Then I put on a jacket because it was cold."

The A's offense wasn't cold, even if its individual members were. With Colon, now 3-0, allowing just one single in the first four innings, the A's built up an 8-0 lead, then found themselves in the curious position of having to sweat out scoring four more times in the fifth.

More than anything, the A's needed to make sure the game was official by getting through the bottom of the fifth. They slowed that process with a four-run rally in the top of the inning.

"It was OK," a smiling Colon said of watching the lead built to 12-0. "I just waited and then went back on the mound."

His teammates weren't so sure. Games aren't official until five innings are in the books, and the rain was starting to come down more heavily.

"I'm not going to lie, that (thought) did get in there," catcher John Jaso said. "Let's call the game."

Colon did give up a pair of two-out singles in the bottom half, but ultimately the game was made official when Stephen Drew popped out to shortstop Jed Lowrie.

From that point, the only questions were just how big the margin of victory would be, and when (and if) the umpiring crew would decide to call it off.

Colon had just struck out the side in the seventh when the umpires ordered the tarps on to the field and the players into the clubhouses to see if the weather would break. It didn't.

"I can tell you this," A's pitching coach Curt Young said. "Bartolo wanted to pitch eight."
