It's not an earth-moving trade, by any means. Jackson is only hitting .238 with one homer and 11 RBIs in his first season back from Valley Fever and his acting talent won't be needed in the American League West race.
Demel, meanwhile, won't fix Arizona's well-documented bullpen problems by himself when he reports straight to the big leagues.
But the move primes the pump for what could be a busy trading season in Phoenix over the next seven weeks. Arizona is thought to be one of the league's biggest sellers with pitcher Dan Haren(notes) serving as one of the most coveted arms on the market. Justin Upton(notes), Ian Kennedy(notes) and Mark Reynolds(notes) should be untouchable since they'll serve as the rebuilding project's core, but pieces like Kelly Johnson(notes), Adam LaRoche(notes) and Brandon Webb(notes) (if he somehow proves healthy) might not be around long to endure the four-hour wait for a pie at Pizzeria Bianco.
With the D'Backs already 11 games out of first and the other NL West division teams set up for a good run of success the next few years, retooling is the smartest decision for general manager Josh Byrnes. Unfortunately for D'Backs fans, that likely means seeing a lot more of the recently acquired Dontrelle Willis(notes) than they would have liked. The desert trading season is now open.
