The Washington Nationals and Arizona Diamondbacks open a three-game series Friday at Chase Field with first pitch scheduled for 9:40 p.m. ET, and Merrill Kelly is lined up to start for Arizona while Foster Griffin is expected to take the mound for Washington.
Kelly enters with a 5-3 record and a 5.06 ERA; Griffin is 6-2 with a 3.76 ERA. Arizona (33-29) sits second in the NL West, and Washington (31-32) is third in the NL East, leaving both clubs within reach of divisional positioning as the weekend begins.
The matchup matters now because it sets the tone for a three-game set that both teams can use to climb toward.500 or to protect their standing in competitive divisions. The Diamondbacks carry the better record into Phoenix, but their starting numbers are mixed: Kelly has been durable enough to collect decisions but his ERA suggests Washington’s lineup could find traction if he doesn’t tighten command.
Availability is an immediate concern. Arizona lists several players on the injured list, including Corbin Burnes on the 60-day IL and Lourdes Gurriel Jr. on the 10-day IL, among others. Washington is dealing with its own absences, most notably Jake Irvin on the 15-day IL and Josiah Gray on the 60-day IL, leaving both pitching staffs to work around missing depth in advance of the series.
What to watch when the game starts: the simple contrast between the starters. Griffin’s 3.76 ERA and 6-2 record indicate he has managed to limit damage this season; Kelly’s 5.06 ERA and 5-3 line show results that are uneven but serviceable. How each manager balances injured-list losses against bullpen usage and lineup construction will matter immediately — both teams could be playing their most available lineups, or making short-term shifts to compensate for key absences.
Practical details for fans: the first of three is at Chase Field, 9:40 p.m. ET Friday; the series continues Saturday and Sunday. Beyond the box score, the series will offer a midseason read on depth — whether Arizona can absorb multiple long-term IL entries while holding pace in the NL West, and whether Washington can navigate its own sidelined pitchers and stay competitive in the NL East.
The unresolved question heading into first pitch is straightforward: will either club make last-minute roster or lineup changes that alter the matchup before 9:40 p.m. ET? Managers must set and submit their lineups and any roster moves prior to the opener, and those decisions will show how seriously the injuries listed are shaping on-field strategy for this Nationals vs Diamondbacks meeting.
