SEATTLE -- Outfielder Braden Bishop, the Mariners' No. 5 ranked prospect per MLB Pipeline, was promoted to the team's 40-man roster on Friday in a move that will prevent him from being exposed to other teams in next month's Rule 5 Draft.
With Bishop's addition, the Mariners' 40-man roster is now at 34 players. The deadline to protect eligible players from being exposed to the Rule 5 Draft is Tuesday.
Bishop, 25, posted a .284/.361/.412 line with eight home runs, 33 RBIs and five stolen bases in 84 games for Double-A Arkansas last season before being hit by a pitch that broke his right forearm in mid-July.
Bishop has recovered from season-ending surgery to repair his arm and is expected to be fully healthy for the start of Spring Training.
Bishop, who was a third-round Draft pick out of the University of Washington in 2015, has impressed the Mariners with his offensive development as well as his speed and ability to play center field.
Bishop was given the Dan Wilson Community Service Award at the end of the 2018 season for his off-field efforts, both in the Little Rock, Ark., community and with the 4MOM charity he has led to raise money and awareness to find a cure for Alzheimer's disease.
