 Starting Pitcher Felipe Rivero: Felipe played at three different levels in the Nats farm system in 2014. He began the season at the Rookie level, and finished the season with Harrisburg in Double-A. He spent most of his season in Harrisburg making 10 starts for the Senators, compiling a record of 2-7 with a 4.12 ERA.

He allowed 30 runs on 45 hits in 43 and two-thirds innings. He was able to strike out 38, while only walking 18.

He is the 16th ranked prospect by in the Nationals chain.’s scouting report on Rivero is as follows.

"Rivero throws his fastball in the low-90s with tailing action. His curveball flashes good potential, though his changeup is the more consistent of his two secondary offerings. Rivero throws a lot of strikes, but he doesn’t always repeat his delivery well and gets hit when he leaves the ball up in the zone. There’s is a lot of potential in his lithe frame if he can harness it." also added that he can command his fastball to both sides of the plate getting him a lot of groundball outs. He has raced through the Nationals system and is in great shape for a player in his developmental stage.
