John Jaso C/DH OAK 7 Days

Jaso was placed on the 7-day concussion DL on Monday.

Jaso has mustered just one at-bat since last Wednesday, as concussion symptoms have grown worse over the last two weeks. The Athletics acquired Geovany Soto from the Rangers on Sunday, leaving the bulk of catching duties to Soto and Derek Norris during Jaso's stay on the disabled list.

Jaso will likely be placed on the 7-day concussion disabled list Monday, the San Francisco Chronicle reports.

Jaso has been experiencing concussion symptoms for a couple weeks, and it appears the A's will place him on the DL to open a roster spot for Geovany Soto, who was claimed off waivers. It remains to be seen when Jaso will play next, as he will need to be medically cleared of his symptoms before doing so.

Jaso has been experiencing concussion symptoms that have worsened over the past two weeks, Susan Slusser of the San Francisco Chronicle reports.

This would seem to help explain why Jaso has been out of the lineup for the past three games, as well as why the team decided to trade for Geovany Soto on Sunday despite its ample depth at catcher. Jaso doesn't appear in danger of landing on the 7-day DL at the moment -- in fact, he was able to pinch-hit Saturday -- but a decline in playing time could be on the horizon. Concussions aren't foreign territory for Jaso, as the head injury ended up costing him much of the second half of the 2013 campaign as well.

Jaso was 0-for-3 on Wednesday which extended his hitless streak to 17 at-bats.

Jaso has seen his batting average fall from .285 down to .269 during his current slide. Of more concern for Jaso is his .347 OBP so far in 2014, coming on the heels of OBP's of .394 and .387 in 2012 and 2013. He does not hit for a lot of power, but his value was in how often he got on base in the past two seasons, something he is not doing nearly as well in 2014. He should continue to get almost all of the at-bats agaisnt right-handed pitchers in his platoon with Derek Norris.
