Athletics optioned RHP Tanner Anderson to Triple-A Las Vegas.
The 26-year-old hurler owns a 6.04 ERA, 1.66 WHIP and 18/7 K/BB ratio over 22 1/3 innings for the big league club this season. It’s unclear if this is actually a demotion for Anderson, or simply to keep him on schedule through the All-Star break, as he wasn’t scheduled to pitch over the weekend. Paul Blackburn has been recalled from Triple-A to take his place on the active roster.
