Rendon, currently hitting .163 with a .293 on-base percentage and .327 slugging percentage in 14 games with Double-A Harrisburg, was the No. 6 overall pick in the 2011 First-Year Player Draft. He'll be joined there by outfielder Brian Goodwin, infielder Jason Martinson and right-handed pitchers Paul Demny, Christian Garcia and Ryan Perry. Washington will also send a pitcher and infielder to be announced. Rendon and Perry are the only Fall Leaguers on the Nats' 40-man roster.
They will be managed by D-backs third-base coach Matt Williams, and Nationals rehab coordinator Mark Grater will serve as the Salt River Rafters' pitching coach.
Goodwin is hitting .219 in 37 games with Harrisburg after posting a .324 average and .979 OPS in 58 games with Class A Hagerstown earlier this season. Martinson, a "taxi squad" member who will only be activated Wednesdays and Saturdays in the Fall League, is a shortstop who has split his season between Hagerstown and Class A Advanced Potomac, posting a combined .254/.349/.445 line.
Demny and Perry are both pitching for Harrisburg, and Perry has posted a 2.82 ERA in 12 starts after struggling as a reliever with the Nationals and Triple-A Syracuse. Garcia has posted a 1-1 record, 0.61 ERA and 11 saves in 24 appearances for Triple-A Syracuse this season.
