SAN FRANCISCO -- The A's bolstered their bench as they transitioned to National League play for a two-day tour at AT&T Park, adding Mark Canha to their roster ahead of Wednesday's game against their Bay rival Giants.
The versatile Canha, who can play all three outfield positions along with first base, takes the roster spot of reliever Michael Brady. The right-hander was optioned to Triple-A Nashville after saving the A's bullpen in Tuesday's loss to the Giants by way of six innings in relief.
Right-hander Chris Smith now assumes that long-relief role, breaking from the starting staff with right-hander Kendall Graveman anticipated back from the disabled list Thursday.
