The Los Angeles Dodgers revamped their roster this offseason with a flurry of moves during the winter meetings, trading away several popular players in an effort to improve the team's defense and chemistry.

New president of baseball operations Andrew Friedman and general manager Farhan Zaidi also acquired some starting pitchers to shore up the back end of an already promising rotation for 2015.

The Arizona Diamondbacks needed to be active this offseason after an MLB-worst 64-98 record in 2014.

The Los Angeles Dodgers have won 92 and 94 games the past two seasons, as well as the National League West both times, and are once again considered by many (if not most) to be the favorites in that division in 2015.

The Arizona Diamondbacks have spent a hefty sum of money to bring aboard a young Cuban talent with lots of upside.

No, this is not a delayed reaction to their signing of right-handed slugger Yasmany Tomas. The Diamondbacks have bagged another one: Yoan Lopez.

The Arizona Diamondbacks are feeling optimistic after an active offseason. Change was certainly expected following a season in which the D-Backs finished 64-98—worst in MLB.

With the addition of young pitching and Cuban slugger Yasmany Tomas, the 2015 team has a new feel to it. 

Andre Ethier was once a pillar of the storied Los Angeles Dodgers organization, so stable a contributor that the previous ownership/front-office regime gave him a heavy eight-figure contract.

There's less than three months remaining until Opening Day, and the Los Angeles Dodgers look decidedly different than they did at the beginning of the offseason.

For starters, the front office was stripped down and replaced with a new regime headed by president of baseball operations Andrew Friedman and general manager Farhan Zaidi.

The Los Angeles Dodgers’ rotation is undoubtedly the strength of the team. It is loaded.

Two Cy Young winners head the staff, and the back half is talented as well. Legitimate arguments can be made that Clayton Kershaw, Zack Greinke and Hyun-jin Ryu are each among the top 20 pitchers in all of baseball, and new acquisitions Brandon McCarthy and Brett Anderson have question marks but are talented.

The Arizona Diamondbacks enter 2015 with much uncertainty regarding their starting rotation.

According to the depth chart, Josh Collmenter is listed as the team's top starting pitcher. He is followed by Rubby De La Rosa, Jeremy Hellickson, Allen Webster and Vidal Nuno.

One of the Los Angeles Dodgers' biggest weaknesses last season was their bullpen.

It was no secret, and the numbers didn't lie. Los Angeles relievers in 2014 surrendered more earned runs than 18 other bullpens in the majors, and only four other relief corps finished the year with a higher walk rate.
