6:15pm: Topkin adds that each of Uwasawa, Brantly, and Smith have upward mobility clauses in their contracts rather than traditional opt outs, meaning that each can request to be made available to the other 29 clubs, at which point if a club agrees to give a given player an active roster spot the Rays will have the choice between adding the player to their 40-man roster or trading him to the interested team. Per Topkin, Brantly, Uwasawa and Smith have all told the Rays that they wish to use their assignment clauses.

10:57am: The Rays reassigned right-handers Naoyuki Uwasawa, Burch Smith, and Joe Record, catchers Francisco Mejia and Rob Brantly, and outfielder Jake Mangum to their minor league camp on Friday.  Manager Kevin Cash told reporters (including Marc Topkin of the Tampa Bay Times) that while none of the six players would be making the Opening Day roster, the Rays were hoping the entire group would remain as minor league depth.

Uwasawa, Smith, and Brantly have some say in their futures, as each of the trio can opt out of their minor league contracts if they aren’t included on the big league roster.  Erasmo Ramirez is another veteran in camp on a minors deal, yet Topkin reports that Ramirez will report to Triple-A and pass on exercising his opt-out clause.

Uwasawa is perhaps the most interesting name in the group, as the 30-year-old is making the jump to MLB after nine seasons in Nippon Professional Baseball with the Hokkaido Nippon-Ham Fighters.  The righty signed a split contract with the Rays that will pay him $2.5MM in the majors and $225K for his time in the minors, as well as a $25K signing bonus and $1MM worth of incentive clauses that would start to kick in if Uwasawa pitched at least 70 big league innings this season.

Though Uwasawa was offered guaranteed contracts by other MLB teams, he chose Tampa Bay “because the success and the rich history of pitching development really intrigued me,” as the right-hander said in a statement at the time of his signing.  It isn’t yet clear if Uwasawa will now stay with the Rays, as he told Topkin (X link) that he would be speaking with his agent to weigh options, including opting out if another team is willing to give him a clearer shot at pitching in the bigs.

Uwasawa didn’t help his case for a roster spot by posting a 13.03 ERA over four appearances and 9 2/3 innings in Spring Training, though he looked a lot sharper in his most recent Grapefruit League outing — he held the Orioles to one run on four hits and a walk over four innings on March 15.  As both Topkin and Cash noted, some adjustment time was inevitable for Uwasawa in his first exposure to the North American style of baseball.

With Brantly and Mejia now cut, it essentially finalizes Alex Jackson’s expected role as the Rays’ backup catcher behind Rene Pinto.  The catching position has long been both a revolving door and a question mark for the Rays, and Topkin feels another backstop might still be added if the Rays like another name who might become available as rival teams also shed players from their spring rosters.
