Reyes hasn't played in the majors since severely spraining his ankle April 12 in Kansas City (on the play pictured above).
Reyes, 30, is hitting .395/.465/.526 with two doubles and a home run in 43 plate appearances this season. In 160 games for the Marlins last year, he hit .287/.347/.433 with 37 doubles, 12 triples, 11 homers, 40 steals and 86 runs.
In six minor-league rehab games prior to Monday, Reyes was hitting .400 with a double, two stolen bases and six runs scored.
With Reyes out of the lineup, Munenori Kawasaki got the majority of the playing time. And while he's a fan favorite and very entertaining, he's also not a very good hitter. His line after Monday's loss to the Rays sits at .225/.337/.325, so Reyes is a big upgrade.
The Blue Jays had an 11-game winning streak snapped Monday, but the important thing is they're now in contention, 5.5 games out in the AL East and only three back of a wild card spot.
