BOSTON -- The Red Sox have discussed potential trades with the Athletics and "unsuccessfully asked" about outfielder Mark Canha, according to Susan Slusser of the San Francisco Chronicle.

Slusser notes that Oakland, which currently has five starters on the disabled list, is looking for starting pitching depth on the trade market. While the Red Sox don't have much at the major-league level, they do have recent call-ups Jalen Beeks and Justin Haley as potential chips in the upper minors.

Canha, 29, has hit .250/.322/.452 with nine homers in 57 games for the A's this year, appearing at all three outfield positions and first base. He has been very good against lefties, OPSing .969 (as opposed to .643 against righties) and hitting seven of his nine home runs against southpaws.

Canha has started 52 of Oakland's 57 games since making his season debut on April 10 and is under club control for three seasons after this one. He likely won't come cheap due to Oakland's high usage of him and Boston's need for improved offense against left-handed pitching.
