The Nationals perceive the organizational depth beyond the 25-man big league roster as an under-the-radar success. In recent years, the Nationals’ best minor leaguers developed in the lower rungs. Those players have ascended, and now many of them have reached Class AA or AAA, ready to be plucked by the big club if needed.

“That’s part of the organizational strength that we have,” Manager Matt Williams said. “There’s only so many spots on the roster. But there’s a lot of very qualified folks here. That’s a good thing.”

The quality and quantity of serviceable-at-worst players in the upper levels of their system, especially pitchers, stands out. This year, Class AAA Syracuse’s opening day bullpen will include Ryan Mattheus, Xavier Cedeno, Christian Garcia and Manny Delcarmen. Their outfield includes Tyler Moore, Steven Souza and Brian Goodwin. As one minor league coach put it: “We’re going to have to say, ‘Okay, which guy do we take?’ It used to be, ‘We got to take him?’ ”

The Nationals’ depth in the lower rungs of their system has been helped by an improved pipeline from Latin America. The Nationals are starting to spend more on individual players, but under Johnny DiPuglia’s watch, the Nationals’ staff in the Dominican Republic sends more and better prospects to the States. Pedro Severino, a 20-year-old catcher starting the year in Class A Potomac, is a prime example. See also Hagerstown outfielder Rafael Bautista, a star on last year’s Gulf Coast League juggernaut.

Another interesting nugget: When Mike Rizzo was talking about the Nationals’ youngest wave of pitchers, he lumped right-hander Austin Voth in with top prospect Lucas Giolito and Jake Johansen, the Nationals’ first draft pick last year.

Voth, 21, was a strikeout-to-walk beast in college at Washington, and the Nationals chose him in the fifth round. In 45 1/3 innings last year at three levels, Voth struck out 55, walked six and punched up a 1.75 ERA. He throws a sinker in the low 90s, and Nationals officials rave about his feel for pitching. He’s a pitcher you may not know much about that could rise quickly through the system.

One last note: Left-handed pitching prospect Sammy Solis will start the year at extended spring training in Florida with a back injury. The issue first surfaced in March and is expected to be a minor setback.

Likewise, veteran lefty reliever Michael Gonzalez will start the year at extended spring training to build up innings.
