Domingo Santana Is the Player to Be Named Later in Hunter Pence Deal

Add another top-10 prospect to the Hunter Pence deal. In a deal that didn't have to be made, the Phillies shelled out a heap for the 28-year-old outfielder. With the addition of Domingo Santana, the overall package is now roughly close to the package the Phillies sent to the Blue Jays for Roy Halladay.

Domingo Santana, 19, is a very young, toolsy outfielder with lots of upside. Standing 6'5, 200 pounds, his best tool is his power potential, which he began displaying more this year, hitting a career-high seven homers and a .166 isolated slugging percentage, up from .115 last year at the same level.

While he's demonstrated a very good walk-rate in the minors entering this year, he's struck out much too often. His strikeout rate has been a career best this year but remains a very poor 30.7 percent of plate appearances. If he would continue showing marked improvement, while maintaining his walk rate, he'd have the potential to be another top 50 prospect.

Like many of the prospects in the Phillies system, Santana was a boom or bust prospect. He could have been another Ryan Howard or could have been another Anthony Hewitt. Sooner or later, giving up all these top prospects will come back to haunt the team.
