📣 DAD’S TAKEON COLBY THOMAS

Look at this guy with his yellow headband and matching wristbands like he's about to teach a Jazzercise class in 1985. You're playing baseball in Oakland, not filming an aerobics video, junior. And batting .225 with that coordinated outfit is like showing up to a job interview in a three-piece suit and forgetting your resume.

ABOUT COLBY THOMAS

Colby Thomas is an outfielder for the Athletics who's still building his big league resume. He had a monster game against the Angels in September, going deep for a three-run homer and driving in three total while scoring four runs in a blowout win. Since he doesn't have official rookie cards yet, you're mainly looking at his base cards and any inserts from when he got called up. If you're hunting his stuff, keep an eye out for numbered parallels and autographs, since those will be the scarcest versions of his early cards.

Colby scored a season-high four runs in a 17-4 victory over the Angels on September 6, going 2-for-5 with a homer, a walk and three RBI. His three-run shot in the top of the second inning gave the Athletics a 7-0 lead.
