Adam Lind's swing is so sweet these days that diabetics should be banned from watching it.

In his past four games after returning this past Saturday from a prolonged stint on the disabled list, Lind has crashed four home runs including a grand slam to centre field Wednesday against the reeling Kansas City Royals.

The slam, the second of Lind's career, came on the second pitch he saw from reliever Nate Adcock in the sixth inning and shot the Jays out to a 9-4 lead in a game they would win 9-8 by the skin of their teeth.

Octovio Dotel would give up a three-run homer in the eighth to make it a two-run game and in the ninth Casey Janssen came on and gave up a two-out RBI double before retiring Melky Cabrera on a pop to short to end the game and earn his first save since Aug. 31 of 2009.

"It was a chance to get him in and shut the game down," manager John Farrell said of why he picked Janssen. "When we were up two I felt Janssen had the ability to control the running game and execute pitches."

Janssen has closed out games before, saving six games in 2007.

"The ninth, the sixth, the seventh, they're all the same to me. It's three outs," Janssen said. "I try to not make it as big as the situation presents itself."

The at-bat for Lind came about due to Royals' manager Ned Yost not wanting to pitch to Jose Bautista with two out and first base open. So after an initial Adcock ball, the Royals walked Bautista, the Major League home run leader with 20, to face Lind.
