John Jaso C/DH TB 2 Months

Jaso (concussion) agreed to a one-year, $3.175 million contract with the Rays on Friday, avoiding arbitration, Marc Topkin of the Tampa Bay Times reports.

Jaso appeared headed for a big payday in his third year of arbitration after posting a .800 OPS and seven homers in the first half of the 2014 season, but he battled concussion issues and ineffectiveness en route to a .675 OPS and two homers in the second half. Thus, he had to settle for a relatively modest bump in salary (from $2.3 million). Jaso appears primed to open the year as the primary option behind the plate, ahead of Rene Rivera, but the Rays have reportedly discussed giving him some time at first base and in the outfield.

Jaso could see time at first base and in the outfield for the Rays in 2015 according to President of Baseball Opertations Matthew Silverman.

Over his 480 games in the majors, Jaso has only made two appearances anywhere other than catcher or DH, so this is an interesting development to say the least. Recently acquired from Oakland, the 31-year-old veteran is viewed as a bat-first player by the Rays and for good reason, as he sports a career .359 OBP and 12.6 percent walk rate. Jaso has been adequate behind the plate in his career, but lingering effects from multiple concussions will likely limit his time there going forward.

Jaso was traded to the Rays on Saturday, the San Francisco Chronicle's Susan Slusser reports.

The deal nets the A's Ben Zobrist and Yunel Escobar, as the A's have now traded their two best catchers from 2014. Jaso is an ideal option to take over the strong side of a platoon at catcher with Rene Rivera, as the left-handed hitting backstop hit .272 against righties and just .167 against southpaws last season. Over a full season, Jaso could hit close to 10 homers with a solid average for the Rays.

A's GM Billy Beane said Wednesday that Jaso (concussion) has been cleared for all activity, Jane Lee of MLB.com reports.

This is encouraging news, though Jaso's future behind the plate remains clouded. While doctors have cleared him to catch again, it's uncertain how much Jaso will catch in 2015 after he again missed significant time due to recurring symptoms at the end of last season. The A's may be inclined to take a cautious approach, though his options are limited with Billy Butler signed to be the team's primary DH. It's also possible the team could look to get Jaso involved at first base.

Jaso (concussion) still hasn't been cleared by MLB for baseball activities.

If Jaso returns next year, catching seems improbable given the severity of his concussions. The A's are interested in him as a DH, however.

Jaso (concussion) won't play again this season, John Hickey of the Bay Area News Group reports.

Jaso has been out of action since late-August, and he doesn't appear to be ready to return to the field anytime soon. In the meantime, look for Derek Norris and Geovany Soto to see the majority of the reps behind the plate.

Jaso will meet with a concussion specialist before the end of the week, John Hickey of the Bay Area News Group reports.

If Jaso checks out OK, he could be cleared to resume hitting at some point next week, though there remains a distinct possibility he does not play again this season. The 30-year-old's symptoms recently resurfaced, resulting in what's now been more than a week-long shutdown period.

Jaso (concussion) has not been cleared to resume baseball activities, Susan Slusser of the San Francisco Chronicle reports.

Jaso appeared close to a return earlier this month, but the team ended up shutting him down after his symptoms resurfaced. He's been shut down from all baseball-related activities for close to a week now, and at this point, appears unlikely to play again this season.

Jaso (concussion) has not yet been cleared to play, and will cease baseball activities for the time being, the San Francisco Chronicle's Susan Slusser reports.

He will travel back to the Bay Area, and his timetable for return is unknown. Manager Doug Melvin says it's too soon to say Jaso is done for the season, but that doctors want to get him into a different routine away from the field for now. In single-season leagues, it's probably time to start looking for other options.

Jaso (concussion) will visit a concussion specialist in Pittsburgh on Wednesday, after which he could be cleared to return to the Athletics, John Hickey of the Bay Area News Group reports.

The exam will clear Jaso to be activated this week, as expected, but his amount of immediate playing time will be unknown until his status is more clear. He likely won't be afforded much time at DH due to the acquisition of Adam Dunn on Aug. 31, while he may not be available as a backstop right off the bat, either.
