Game 97 lineups: Nats at Diamondbacks (with roster moves)

PHOENIX - It's another scorcher outside Chase Field, but thankfully the roof is closed inside and it'll be another comfortable day inside the big hangar for a ballgame as the Nationals and Diamondbacks wrap up their weekend series.

There's plenty of intrigue to this one, with the Nats scrambling to get enough healthy outfielders on site to field a starting lineup. No official word yet on the moves, but Ryan Raburn is heading to the bereavement list following his grandfather's death and Chris Heisey probably is heading to the disabled list after tweaking his groin last night.

Whoever ends up in the lineup will face a stiff challenge in Robbie Ray, the All-Star left-hander and former Nationals prospect (sent to Detroit in the Doug Fister deal back in 2013). The Diamondbacks also will face a challenge, though, with Stephen Strasburg on the mound for the Nats. Strasburg has been outstanding in four of his starts at Chase Field (3-0, 2.42 ERA) but terrible in one other start in 2015 (eight runs in 3 1/3 innings).

Update: The Nationals have recalled catcher Pedro Severino and selected the contract of outfielder Andrew Stevenson from Triple-A Syracuse. Heisey has been placed on the 10-day DL, Raburn has been placed on the bereavement list and outfielder Jayson Werth has been transferred to the 60-day DL to open a spot on the 40-man roster for Stevenson.
