Jaso likely to move to 15-day DL due to concussion

CINCINNATI -- Still experiencing concussion symptoms, A's catcher John Jaso remained in the Bay Area on Tuesday while his teammates opened a six-game road trip in Cincinnati, and there are no plans for him to rejoin them.

"Not yet," manager Bob Melvin said.

It's been 12 days since Jaso was placed on the seven-day concussion disabled list, which likely means he'll be transferred to the 15-day DL this week.

This is the third concussion of Jaso's career, though the backstop has said many times that he never before experienced such lasting symptoms until now, which includes buzzing in his ear each time he wakes.

"He continues to improve as far as how he feels after riding the bike and all," Melvin said, "but still until we actually get him into baseball activities, there's really no way of knowing how to forecast his schedule."

Jaso had a .415 on-base percentage in the 16 games before he was sidelined, production that has since been missing at catcher, where replacement Stephen Vogt has hit .188 with a .229 on-base percentage in 11 games spanning two stints with the A's this year.
