Cuban third baseman among several offseason acquisitions with high expectations in 2015

Tomas headlines new additions for D-backs

PHOENIX -- Once the longest-tenured player on the D-backs, catcher Miguel Montero was dealt to the Cubs in December. Veteran pitcher Wade Miley followed shortly thereafter as new general manager Dave Stewart went about putting his stamp on the roster.

With pitchers and catchers set to report to Salt River Fields in just over a week, here's a look at some of the new faces for the D-backs in 2015:

RHP Rubby De La Rosa: De La Rosa came over from the Red Sox in the Miley deal and the D-backs are excited about his live arm. He has made an impression on his new teammates by being at Salt River Fields quite often over the past month.

RHP Jeremy Hellickson: Hellickson was the first piece that Stewart acquired during the offseason, nabbing him from the Rays in exchange for a pair of prospects. The D-backs are counting on Hellickson to be a part of their rotation.

Outlook: Hellickson, SP, ARI

C Oscar Hernandez: The trade of Montero left the D-backs with Tuffy Gosewisch as their only catcher on the 40-man roster. Hernandez was selected out of the Rays organization during the Rule 5 Draft and will have to spend the entire season in the big leagues or be offered back to Tampa Bay.

RHP Yoan Lopez: The D-backs shelled out a little more than $8 million for the Cuban free agent -- plus a 100 percent tax on the signing for going over their international pool allotment. Lopez might need some Minor League seasoning, but the team will give him a long look this spring.

Top Prospects: Lopez, ARI

LHP Robbie Ray: The D-backs acquired Ray from the Tigers in a three-team deal that sent shortstop Didi Gregorius to the Yankees. Ray will compete for a spot in the starting rotation this spring.

3B Yasmany Tomas: Tomas was signed to the largest contract in franchise history -- $68.5 million over six years. Though he played a lot of outfield in Cuba, the D-backs believe he can play third base and will give him every opportunity to win the starting job there this spring.

Outlook: Tomas, 3B, ARI

RHP Allen Webster: Webster was also acquired from the Red Sox in the Miley deal. Though he has had limited success in parts of two big league seasons with Boston, the D-backs believe that Webster can become a key part of their rotation.
