The 24-year-old Ross will look to continue a trend where Nats starters Max Scherzer and Stephen Strasburg dominated San Diego on Friday and Saturday, respectively. In the last six games, Nats starters have allowed six earned runs in 43 2/3 innings for a 1.24 ERA. In that span, they have struck out 61 and walked only eight.
The Padres have not scored a run against the Nats since the fourth inning Friday night.
Ross is 2-0 with a 5.32 ERA in four starts. He has 20 strikeouts in 23 2/3 innings. He struck out eight and allowed one run in eight innings in a 10-1 win over Seattle on May 23.
San Diego counters with right-hander Jhoulys Chacin (4-4, 5.74 ERA). Ryan Zimmerman swings at a .313 clip with two homers against the veteran.
