3) Angels internal option to replace Shohei Ohtani: Luis Rengifo
If Ohtani does leave and the Angels choose to focus on bringing in pitching this offseason, they won't have a solidified DH. Guys like Mike Trout and Anthony Rendon figure to get much more time there, and hopefully that'd help keep them healthy, or at least healthier.
The player I believe will replace Ohtani's spot in the lineup is Luis Rengifo who finished as strongly as any Angels player has in a long time this past season and deserves a look in an everyday role. Rengifo was one of the best players in baseball in the second half and was one of very few bright spots for the Angels in an abysmal August before he went down with a season-ending injury.
Rengifo figures to play a key role in 2024, but he doesn't have a solidified everyday role. He can play three of the four infield spots, but they're taken up by Anthony Rendon, Zach Neto, and Brandon Drury. He can play the outfield as well but that's full with Taylor Ward, Mike Trout, and Mickey Moniak there with Jo Adell vying for at-bats as well.
Rengifo as of now is the Anthony Rendon replacement at third base who will earn spot starts everywhere else that he can, but if Ohtani comes back or the Angels sign someone to take Ohtani's spot, he simply doesn't have that everyday role. Ohtani leaving opens that up. I'd expect him to play mostly the field with Rendon getting a lot of DH at-bats in an attempt to keep him on the field in some capacity.
