According to his Facebook page, Rhyne Hughes has been called up from AAA and will join the club in Boston. Corresponding roster move not yet known, and no corroboration from the club at this point.
In 14 games with Norfolk this season, Ryan's batting line is:
BA / OBP / SLG / OPS
.375 / .434 / .708 / 1.142
In case you're curious, Garrett Atkins' batting line in 15 games with the parent club is:
.241 / .268 / .315 / .583
....although the smart money is on RP Alberto Castillo returning to Norfolk.
