The Red Sox had been searching for a right-handed hitting outfielder with the ability to play center field for a while, in part because of concerns top prospect Ceddanne Rafaela — already a pristine defender in center — still has a ways to go with his offensive development, especially when it comes to plate discipline. The O’Neill move makes it more likely, but not certain, that Rafaela begins the year at Triple-A, though his versatility may win him a spot coming out of spring training. Adding O’Neill, who has dealt with numerous injuries over the past five seasons, gives the Sox some insurance when it comes to Rafaela but will still give the top prospect a serious chance to contribute in 2024....
They are now less likely to pursue a big right-handed outfield bat (like Lourdes Gurriel Jr., Teoscar Hernández or Jorge Soler on the free agent market) but could still try to add a righty who can DH while mixing in at first base (with second base another hole to fill). If the Sox believe Adam Duvall can cover some first base (a position he played early in his career), he makes a lot of sense as another option to join the mix. At first glance, adding someone like O’Neill for a year made more sense for the Sox than signing someone like Gurriel or Hernández who will command a three or four-year contract. With Abreu, Duran, Rafaela and Yoshida all under control for a while and top prospect Roman Anthony on the way, it doesn’t appear Breslow wanted to block any of his young players with a long-term deal. The only chance something like that goes back on the table is if a major trade for starting pitching requires someone like Abreu, Duran or Rafaela to be dealt.
