The Red Sox's upside in VonScio's trade idea could be acquiring prospects from San Diego's farm system, which has highly rated players like catcher Ethan Salas and shortstop Leo De Vries. However, would San Diego be willing to part with either of them to wait patiently for Casas to improve at the plate?

Red Sox manager Alex Cora called Triston Casas' defense "inconsistent." He added, "We believe he can be much better."

Triston Casas hit a three-run home run that helped propel the Boston Red Sox to an 8-3 victory over the visiting Seattle Mariners on Tuesday in the first matchup of a three-game series.
