The Orioles top prospect is here. After a solid, if not noteworthy, campaign for Norfolk this year the Birds have added Chance Sisco to the September roster. This could be more than a cup of coffee to reward a prospect. If the Orioles are prepared to take a leap and bench Mark Trumbo, replacing him with Wellington Castillo, they would improve the team offensively and defensively.
When the Birds were carrying just two catchers this wasn't really an option. Yes, Ryan Flaherty is technically the emergency catcher, but obviously there was no real flexibility there. But with the addition of Sisco, the Birds can now safely have both Caleb Joseph and Wellington Castillo in the lineup at the same time.
This is crucial. Mark Trumbo has been completely unproductive since returning from the DL (.253/.286/.430) and in fact has the lowest OPS of all qualified hitters on the Orioles this season. Even Caleb Joseph, who hasn't accumulated enough AB to qualify, has a higher OPS than the man filling the position that is literally just supposed to hit.
Believe it or not, Wellington Castillo has a higher OPS than Manny Machado, Adam Jones, Chris Davis, and Seth Smith. The Orioles need him to be in the lineup daily as the Orioles push to scrape into the Wild Card game. Depending on who you ask Castillo is not a great catcher, hence why the team would be better served having him DH most of the time and Joseph catch the majority of the remaining games.
A rotation between catcher and DH would allow Joseph and Castillo to be in the lineup together nearly every day. Spelling them with occasional starts by both Trumbo and Sisco would keep them fresh. Pedro Alvarez has also joined the team, but his season at AAA hasn't been much better than Trumbo's so I don't consider him a factor.
Buck Showalter is notorious for his loyalty to his starters. Mark Trumbo has been afforded a tremendous amount of rope which he has done very little to justify. With the season on the line its time for the team's success to come before personal loyalties. The Orioles now have the man power to make the appropriate changes to the lineup, but we will have to see if they do it.
