Of the three people on this list, I think Braden Bishop is the safest as if an outfielder is signed I think Bishop is second in line to get cut, but I was not expecting Jerry Dipoto to cut Phillip Ervin and Tim Lopes.
Bishop is in a different situation compared to Ervin and Lopes, as he has had limited opportunities in the majors, but he has not done anything with the chances he’s got. Over the past two seasons, Bishop has almost 100 at-bats and has just 11 hits, two of them being for extra bases leading to a .336 OPS.
Bishop might be safe from getting DFA’d since he is still considered a prospect ranking 18th in the Mariners system on MLB.com, and he has also had to deal with multiple injuries which have kept him from receiving regular at-bats which he could have had in 2018, 2019, and last season.
Bishop is now 27 and that title of “prospect” might soon be gone with his age, but because of his defense and potential if he can get some regular at-bats, he should be safer than the two previously mentioned, and if a pitcher is signed a depth reliever might be cut over him.
