News on four Nationals pitchers from Arizona Fall League

MLBPipeline.com's Jim Callis believes the three left-handers the Nationals sent to the Arizona Fall League could all be useful out of the bullpen going forward. Ben Braymer, Taylor Guilbeau and Jordan Mills pitched well in Arizona, playing a part in the Salt River Rafters reaching the title game.

"Guilbeau has the best velocity out of any of them and probably the least control," Callis said. "Braymer had a great year, (being named) Minor League Pitcher of the Year in the organization. I think he is probably more of a reliever. He predicts as more of a reliever than a starter or back-of-the-rotation type of guy. Mills has the best control and probably the best fastball out of all of them.

"I think they are all potentially useful relievers. I don't think any of them is a super key component of a pitching staff, but they could all be useful."

Braymer, 24, went 9-3 with a 2.28 ERA in 28 games (11 starts) this summer. He went 1-0 with a 5.40 ERA in nine games with Salt River.

Guilbeau, 25, went 1-0 with a 2.52 ERA in 28 games for high Single-A Potomac. He recorded 35 strikeouts in 35 2/3 innings.

Mills, 26, went 2-1 with a 2.29 ERA in 15 appearances for Double-A Harrisburg.

The Nats' lone right-hander in the AFL, Luis Reyes, made four starts with the Rafters. His last start was Oct. 27.

He was later diagnosed with right shoulder tightness, according to a club source, so Reyes didn't pitch in November at all.

But Reyes is expected to be fully recovered and ready to go in time for spring training.

Reyes, 24, started 12 games for Double-A Harrisburg, going 5-6 with a 5.18 ERA over 64 1/3 innings.
