Arizona Diamondbacks

There's a new star duo in town in Arizona. Determined to upgrade their starting pitching, the Diamondbacks aggressively added ace right-handers Zack Greinke and Shelby Miller to their rotation earlier this winter.

The San Francisco Giants traded right-handed pitcher Cody Hall to the Arizona Diamondbacks on Wednesday in exchange for cash considerations or a player to be named later, announced Arizona. 

After shocking the baseball world by agreeing to sign with the Arizona Diamondbacks last week, superstar pitcher Zack Greinke was introduced as part of a highly anticipated press conference Friday.

Former Washington Nationals manager Matt Williams has accepted his former job as the third-base coach with the Arizona Diamondbacks, according to John Gambadoro of Arizona Sports.

On Saturday, the Diamondbacks retired his No. 51, and they made the Big Unit a 51-inch corndog. That's a lot of calories, but he deserves it after an epic career. Eat up, Randy!

Last season, the Arizona Diamondbacks finished with the worst record in baseball at 64-98. There were many glaring weaknesses with the team, but it was the 8-22 start that likely buried the D-backs' playoff hopes before the month of May even began.

The Arizona Diamondbacks had a relatively busy offseason entering 2015. Besides cleaning house in several areas of management, they made a number of acquisitions via signings and trades that have had an impact thus far.

The D-backs sit at 8-8 entering Saturday and have showed signs of improvement from their abysmal 2014 campaign. Some of the new players have assisted in that regard.

Here are the early grades for Arizona's offseason acquisitions.

First base is one of the deepest positions in all of baseball, possessing an eclectic crop of talent including power hitters such as Edwin Encarnacion and Anthony Rizzo, high-average hitters like Joey Votto and Jose Abreu and some who are just pure hitters—Miguel Cabrera and Paul
