If Santana is truly back and ready to pitch at a high level, I hate to say this but the odd man out is... Fernando Romero. If the team flounders over the next six weeks, you offload Santana, Lynn, and a few others and recall Fernando. But right now, Romero is not helping the team win many baseball games. And right now, the front office has about five weeks to decide whether to buy or sell at the deadline. You need as many wins as possible during that time and letting Romero work through some struggles isn't aligned with that goal. And if Santana doesn't move the needle, then you sell a bunch of players and let Romero pitch through the second half of the season.
