"Vlad and the Blue Jays had a sort of deadline to bring him to the majors and that time just passed, without that happening," a source said. "The Blue Jays have to decide today if they want him or not, but Guerrero will not return to (a) minor league."
The deadline between Guerrero and Toronto was this past Sunday, but it was moved ahead one day because the slugger missed a game after being hit by a pitch on his hand Saturday.
After going 4-for-5 with a triple and two RBIs for Triple-A Las Vegas on Monday, Guerrero gathered his belongings and went to his home in Anaheim, Calif.
"Guerrero is ready to play today in the big leagues," a source close to the nine-time All-Star said.
Guerrero, 37, batted .358 with four homers and 12 RBIs in 12 minor league games with the Blue Jays' organization. He agreed to a pro-rated deal last month with a base salary of $1.3 million.
The American League MVP in 2004, Guerrero has batted .318 with 449 homers and 1,496 RBIs during his 16-year career in the majors. He spent last season with the Baltimore Orioles, batting .290 with 13 homers and 63 RBIs.
