Toronto's 24th-round pick in the 2004 amateur player draft scattered seven hits and struck out three batters in the first complete game of his career. He improved his 2008 record to 6-1.

Wilkerson's slam in the bottom of the first inning was his second home run this season.

Toronto's other runs scored on Mark Grudzielanek's sixth-inning throwing error and Lyle Overbay's bases-loaded walk in the seventh.

Aaron scored once and had two of the eight hits for the Blue Jays, who have won the first two in a four-game series.

Grudzielanek had two hits and five other players had one for the Royals, whose losing streak grew to six straight games.

Losing pitcher Luke Hochevar (3-4) was charged with five runs -- four earned -- on six hits and four walks in six innings. He recorded four strikeouts.
