Dave Campbell of SportsIllustrated.com notes that there is no guarantee in Guerrero's contract that he will make the major league team.
It's unclear as to where Guerrero would play if he plays well enough to make the club, as he's pretty much just a designated hitter at this point in his career.
The Jays will have to do some roster shuffling if they want to make room for Guerrero's bat.
If the Jays are willing to part with Adam Lind, Edwin Encarnacion could move over to first base. This would open the DH spot for Guerrero.
Lind has struggled since his breakout 2009 campaign, so much so that he's recently been dropped to No. 8 in the lineup.
He's currently hitting just .198/.283/.347 in 101 at-bats this season, so it's clear that he's not producing at the level that Toronto expects from him.
Jose Bautista has also been slumping early this season, even though there are no signs that suggest that he will continue to struggle as the season progresses.
If the Jays were really desperate, they could move Eric Thames to a reserve outfielder's role and try Guerrero out in left field.
We'll see what happens when Guerrero reports to the Jays' extended spring training program in Dunedin, Florida.
