Regular season and spring training game times for all Major League Baseball teams were announced Thursday, including the start times for all Arizona Diamondbacks games at Chase Field.

The Diamondbacks open the spring slate on Feb. 21 against their Salt River Fields training partners, the Colorado Rockies. Game time is at 1:10 p.m. MST.

Most Diamondbacks spring training games will start at 1:10 p.m. or 1:05 p.m., though there are a few night games that start in the 6 p.m. hour.

They will close out spring training with two games at Chase Field — 6:40 p.m. on March 24 and 12:40 p.m. on March 25.

Opening Day for the Diamondbacks' regular season is a night game at Chase Field on March 27 at 7:10 p.m., against the Chicago Cubs. Arizona's opening series is four games against the Cubs from March 27 to March 30, all starting at different times.

The Cubs will have already played two regular season games by March 27, as they face the 2024 World Series champion Los Angeles Dodgers in Tokyo, Japan, on March 18 and 19 at 4:10 a.m. MST.

The Dodgers will visit Phoenix for the first time from May 8-11 and won't be back until Sept. 23-25, the final regular season home series of 2025 for the Diamondbacks.

The earliest start time for a game this season will be 9:10 a.m. MST on April 17 against the Miami Marlins on the road. A three-game series in Chicago against the White Sox June 23-25 is the only one on the schedule without confirmed game times.

Arizona closes the regular season in San Diego against the Padres Sept. 26-28. Game times are 6:40 p.m., 5:40 p.m. and 12:10 p.m.

Most home game start times are 6:40 p.m. on weeknights, 5:10 p.m. on Saturdays, and 1:10 p.m. on Sundays.
