The Arizona Diamondbacks have had plenty of good seasons, but their successes always seem to be fleeting. An NL West title in 1999 was followed by a mediocre 2000, the team that won the World Series in 2001 was a bottom dweller by 2003, the run to the 2007 NLCS was followed by three seasons of mediocrity, and the team that won the division in 2011 fell to third in 2012. None of this is an indictment of the franchise, but it provides a valuable lesson for Diamondbacks fans: enjoy it while it lasts.

There’s no telling what next year holds for the D-Backs, but they appear to be having another good season this year. You can catch the Diamondbacks at Chase Field, 401 East Jefferson Street. Friday, June 21, when they open a series against the reigning NL Central champion Cincinnati Reds. First pitch will be at 6:40 p.m. Tickets start at $5. Visit or call 602-462-6500.
