The first somewhat significant trade of the 2010 season took place yesterday between the Arizona Diamondbacks and Oakland A’s.

I say somewhat because no major names were involved, but I think it was a trade that could help both teams.

Yesterday, the Diamondbacks traded OF/1B Conor Jackson to the A’s for minor league RHP Sam Demel. Here is what both teams got.

As you probably have heard me say throughout the years here, Conor Jackson sounds and looks like a guy who should hit .300 with 30 HRs and 110 RBI every year. Unfortunately, he was never that guy and more so now after suffering from valley fever last year.

In his first three full years in the majors, Jackson averaged .292/.371/.451 with 14 home runs, which is pretty respectable. However, last year Jackson suffered from a rare case of valley fever and saw his hitting line dip to .182/.264/.253 with one HR in 30 games.

Things haven’t been that much better for Jackson in 2010, as he has gotten off to a .238/.326/.331 with one HR start. Jackson has done well against lefties, however, as he has hit .300 with an .833 OPS against southpaws this year.

Jackson does represent an upgrade for the A’s over Eric Patterson in left. Patterson was hitting only .210 with a .262 OBP in 42 games. The A’s could use any upgrade they can find on offense, as they rank 12th in the American League in runs scored and 11th in OPS.

As for the Diamondbacks, I believe this is the first of many moves to come. It wouldn’t shock me to see them unload Kelly Johnson or Adam LaRoche in the near future.

What they get in this trade is a 24-year-old right-handed reliever who posted a 1.26 ERA and 28 K’s in 28.2 IP for Triple-A Sacramento this year. The Diamondbacks’ bullpen is the worst in baseball this year, so any sort of fresh arm is greatly welcomed. If Demel proves himself at the major league level, he could find himself as the Diamondbacks’ closer of the future.

Good trade for both teams.
