No. 4: Ranger Suárez
As fun as it would be to add another top-end free agent starter to the fold, that'd be completely unrealistic. Plus, you really can't go wrong with Ranger Suárez as a fourth starter. Since being inserted into the rotation full-time at the end of the 2021 season, the southpaw has emerged as a legitimate mid-rotation arm.
This past season, he dealt with injuries, but when healthy was mainly effective. He had a 4.18 ERA in 22 starts and 125 innings pitched. He went at least five innings in all but four of his starts and allowed three runs or fewer in 15 of the 22 outings. Most of the time, he was good for at least five innings allowing three runs or fewer, which, in other words, gives this team a chance to win.
As he did last season, Suárez took his game to another level in the postseason, posting a 1.93 ERA in his four starts as the Phillies third starter. He's shown value both in the rotation and out of the bullpen in the postseason, which helps a lot.
Having Suárez as a fourth starter would be a luxury not many teams in the league have. While he'll likely be the team's third starter, it's always fun to dream.
