Pitchers and catchers will take the field for the first time on Feb. 13, with position players reporting Feb. 17 and the first full-squad workout slated for Feb. 18.
The Mariners will then work out daily before beginning Cactus League action with the annual Charity Game against the Padres on Feb. 27 at Peoria Stadium. Last year's game raised more than $106,000 for charities in the Peoria area.
The Mariners will play 16 spring games at Peoria Stadium, including one when the Padres are designated the home team on Feb. 28. The road schedule will include a March 20 contest against the Cubs at their new spring facility being built at the old Riverview Golf Course in Mesa.
The eight night games will be March 8 at the Dodgers in Glendale, March 10 at the D-backs in Scottsdale, March 12 vs. the Cubs in Peoria, March 14 at the Rockies in Scottsdale, March 18 and 21 vs. the Padres in Peoria, March 25 at the Royals in Surprise and March 28 vs. the Rockies in Peoria.
For the first time since 1988, the Mariners won't play outside of the Phoenix area in the final days of spring before opening the regular season. Instead, they'll stay in Arizona and play two exhibition games against the Rockies -- in Peoria on March 28 and at Scottsdale on March 29 -- before flying to Anaheim for a workout day on March 30.
They'll then open the regular season on March 31 against the Angels in Anaheim. The home opener will be April 8 at 7:10 p.m. PT against the Angels at Safeco Field.
Single-game tickets for spring games at Peoria Stadium will go on sale Jan. 4 at 8 a.m. PT on Mariners.com or by phone (800-677-1227) or at the Peoria Sports Complex box office.
