Rays and C/DH John Jaso avoided arbitration by agreeing to a one-year, $3.175 million contract.
It was Jaso's final year of arbitration eligibility. He's slated to serve mainly as a designated hitter for the Rays after coming over from the A's via trade last week. Jan 16 - 1:43 PM

Rays president of baseball operations Matt Silverman indicated Saturday that John Jaso is unlikely to see much playing time at catcher in 2015.

We're happy to hear that for Jaso's sake, as he's had his last two seasons cut short due to concussions. While he was checked out earlier this offseason and cleared for all activity, putting him behind the plate would be dangerous. Jaso figures to see most of his playing time in the designated hitter spot, though he will also play some first base and will give the outfield a shot in spring training.

Rays acquired C John Jaso, INF Daniel Robertson and OF Boog Powell from the Rays for INF/OF Ben Zobrist and INF Yunel Escobar.

The 31-year-old began his career in the Rays organization, spending nine seasons there from 2003-2011. Jaso's fantasy value instantly increases with this deal, as there's likely more time for him behind the dish in Tampa Bay than there would've been in Oakland. He'll now share time with Rene Rivera.

Joel Sherman of the New York Post reports that the Rays will receive John Jaso and two prospects from the Athletics in exchange for Ben Zobrist and Yunel Escobar.

Jaso should platoon with Rene Rivera in Tampa Bay and represents their best option behind the plate offensively. It's unclear at the moment who the potential prospects included in the deal may be.

Susan Slusser of the San Francisco Chronicle reports that the Blue Jays have shown interest in acquiring John Jaso from the Athletics.

The A's are currently fielding calls on some of their left-handed bats, and have a logjam behind the plate and at designated hitter which are the two spots Jaso could be utilized. The Jays see him as a potential backup to Russell Martin. The A's have reportedly inquired about Sean Nolin who could be included in any potential deal.

Athletics general manager Billy Beane said Wednesday that John Jaso (concussion) has been cleared for all baseball activities.

That means he'll be able to catch again, but it remains to be seen how often he'll be behind the plate next season. Jaso's last two seasons have ended prematurely due to concussion issues, so putting him behind the plate at all is a dangerous proposition. The A's are considering giving him some reps at first base in spring training.

John Jaso (concussion) has officially been ruled out for the season.

It's been the expectation for a while, as Jaso hasn't played in a month and just hasn't progressed as hoped from post-concussion issues. That's now two seasons in a row that have been ended by concussions for the 31-year-old. He hit .264/.337/.430 for the A's this season.

John Jaso (concussion) is not expected to return this season.

A doctor failed to clear Jaso to return last week and he has yet to resume baseball activities since then. He hit a solid .264/.337/.430 when healthy this year, but this is now his second straight season that's ended due to concussions. His time as a catcher might be finished.

John Jaso (concussion) failed to be cleared to play by a doctor Wednesday.

Jaso had a meeting with Dr. Mickey Collins in hopes of being cleared to return, but instead Jaso has been told to cease baseball activities for the time being. Jaso has returned to Oakland, and suddenly his return to the A's during the regular season is up in the air.
Wed, Sep 10, 2014 06:22:00 PM

John Jaso (concussion) will be examined by Dr. Mickey Collins on Wednesday in hopes of being cleared to return to action.

He would presumably be ready to play on Thursday if all goes well. However, Jaso isn't expected to be used in more than a pinch-hitting role over the final weeks. He can be dropped in fantasy leagues.

John Jaso is expected to return from the concussion disabled list this week.

But Joe Stiglich of suspects that he will be used primarily as a pinch-hitter down the stretch because the A's "don’t want to subject Jaso to further injury behind the plate given the multiple concussions he’s suffered" and have Adam Dunn locked in as the DH against right-handers. Jaso has posted a decent .767 OPS this season, but he can be dumped in most redraft fantasy leagues.

John Jaso (concussion) could be cleared to pinch-hit Sunday.

Jaso has been doing baseball activities the last few days and hasn't had any post-concussion symptoms. While encouraging, Jaso has a history with concussions and the A's can proceed cautiously with him with Adam Dunn aboard. Fantasy owners shouldn't count on much from Jaso in the final weeks.
Sun, Sep 7, 2014 10:14:00 AM

John Jaso (concussion) ran the bases on Friday for the first time since sustaining his injury.

Jaso still has every intention of returning to the Athletics before the end of the season and has begun to make serious progress towards doing so. With three other capable catchers on the roster, Jaso will be limited to part-time designated hitter duties upon his return.
Fri, Sep 5, 2014 07:00:00 PM

John Jaso (concussion) took live batting practice Tuesday.

It's the first time he's done so since landing on the disabled list last week with a concussion. The A's will proceed cautiously given Jaso's past concussion issues, likely not using him anywhere but DH for the rest of the season. The 30-year-old is feeling better, though, and thinks he'll be back relatively soon.
Tue, Sep 2, 2014 06:17:00 PM

John Jaso (concussion) could resume baseball activities this week.

Jaso has missed the last week of action with concussion-related symptoms, but he's starting to feel better. If he is activated at some point in September, the A's are expected to limit him to DH duty given his history of concussions.
