I'd think about it.
If and when Pedey returns, we'll need to find PAs for Nunez. If Beni is still not hitting lefties, I MAY want Nunez to play LF in some of those games.
(Also, If JBJ is still doing horribly on offense, I might try to get Nunez into the OF vs a few RHPs when JBJ sits a small percent of games vs RHPs more than his normal resting days.)
I do not want JMart in the OF, except for maybe 2 out of 3 games when in NL parks only, as we have no DH.
Other than that, I'm not pushing for any changes right now. (I might choose Lin over Holt more.)
Would you keep playing Beni forever vs LHPs, if he remains at .566 (career) or .273 (2018)?
He's no JBJ on defense, and you can "hide" poor defense in Fenway's LF to some extent. (Nunez has a small sample size, but his OF defensive metrics look good.)
