In order to make room on the 40-man roster, the A's transferred infielder Scott Sizemore to the 60-day disabled list. To make room on the active roster, outfielder Michael Taylor has been optioned back to Triple-A Sacramento.
The Blue Jays claimed Wells off waivers from the Seattle Mariners just before the teams broke camp. Wells failed to win a spot on the M's roster, as they elected to instead go with veteran outfielder Jason Bay.
After being claimed by the Blue Jays, Wells didn't appear in a single game in the majors or minors for the club. It will be interesting to see if he needs time to prepare for the majors or minors before being activated by Oakland, as he's had some serious downtime in between the waiver process.
Wells has the ability to play all three outfield positions, and he's proven a capable hitter during certain parts of his career. He hit an impressive .323/.364/.538 with 11 extra-base hits over his first 99 plate appearances. His production tailed off since, but he's still maintained a batting line of .246/.317/.435 over parts of three seasons in the majors.
