MILWAUKEE -- The Brewers unveiled a 34-game Spring Training schedule on Wednesday that ends with a pair of exhibitions against the Diamondbacks at Chase Field.

Sixteen of the games are at Maryvale Baseball Park, where the Brewers face an uncertain future. Their 15-year lease runs through the end of the 2012 Cactus League season, and club officials have left open the possibility of leaving unless the city of Phoenix, which owns and operates the complex, makes improvements to some of the training facilities.

The Arizona Republic reported earlier this year that the Brewers have the option to sign as many as three two-year lease extensions.

Key games on this spring's "home" slate include a Sunday, March 4 Cactus League opener against the Giants, March 8 and March 29 matchups with the Reds and against the rival Cubs on March 10.

All games at Maryvale Baseball Park are scheduled for 1:05 p.m. Arizona Time.

The team has four split-squad games scheduled during the spring, including April 3, when the Brewers play the Cubs in Mesa, Ariz., in the afternoon and against the D-backs at Chase Field at 6:40 p.m. local time. The Brewers will again play the D-backs at Chase Field to close out the 2012 Spring Training schedule on April 4 at 12:40 p.m. local time.

Tickets for Brewers home Spring Training games will go on sale at 10 a.m. CT on Dec. 5 via the internet at brewers.com and by phone at 1-800-933-7890.
