Kansas City, Mo. ? Mike Sweeney put the ball in play. The unpredictable physics of baseball did the rest.

Sweeney’s two-out, two-run double in the ninth inning skidded past third baseman Eric Hinske, lifting the Kansas City Royals to a 4-3 victory Wednesday over the Toronto Blue Jays.

Terry Adams (3-2) gave up a single to Desi Relaford to open the ninth, then retired Aaron Guiel and Angel Berroa on ground balls. Carlos Beltran followed with a walk before Sweeney delivered. Hinske let the ball play him, and it got past his backhand try and down the left-field line.

“The ball stayed down, and I just couldn’t get to it,” Hinske said.

Beltran raced home from first, easily beating the relay.

“I was at first, and I looked up and Carlos was already at third,” Sweeney said. “I just thought, ‘Wow, he’s going to score here.”‘

Adams flipped his glove in the air in frustration as he walked off the mound.

“I made the pitch I needed to make, and he put the ball on the ground,” Adams said. “It’s out of my hands after that.”

Sweeney’s game-winner off Adams gave the Royals back-to-back victories for the first time since April 9-11, when they took three in a row from Cleveland. Since then, they had lost eight straight series before winning two of three from the Blue Jays.

It was the fourth time this season the Royals won in their last at-bat.

“This is our game,” said Beltran, who hit his 10th homer in the first inning off Ted Lilly for a 1-0 lead. “This is what we have to do. We have to create runs.”

Chris Gomez’s eighth-inning RBI single off reliever Nate Field (2-0) gave the Blue Jays a 3-2 lead. Toronto stranded 13 runners and left the bases loaded three times.

But after giving up the go-ahead hit to Gomez, Field retired six of the next seven batters he faced with three strikeouts.

“I’ve been in that situation a lot this season,” Field said. “You just have to go after guys and throw strikes.”

The Royals turned four double plays in the first five innings behind starter Jeremy Affeldt. But in the fifth inning, after Affeldt made a diving grab of Gregg Zaun’s bunt and threw to second to double off Hinske, the Blue Jays took a 2-1 lead with two well-placed hits.

First, Reed Johnson’s blooper fell just inside the right-field line for an RBI single. Then, Frank Catalanotto’s ground ball ticked off the glove of diving third baseman Joe Randa for a one-run double.

The Royals tied it at 2 in the fifth after Relaford walked, went to third on Berroa’s double and scored when second baseman Orlando Hudson dropped the relay throw.
