Martinez picked up the save Sunday against Boston, allowing a solo home run and no walks with one strikeout during the ninth inning.
Martinez inherited a three-run lead in the ninth frame and offered up a solo home run to Tyler O'Neill to start the inning. Martinez was able to shake off the long ball and retired Masataka Yoshida, Connor Wong and Romy Gonzalez in order to secure his sixth save of the season. Martinez emerged as the Diamondbacks' closer in August, and he's 6-for-6 in save opportunities this month. While manager Torey Lovullo said Friday that he wants to get Paul Sewald back to being a closer, the team opted for Martinez in the ninth Sunday. The 22-year-old has been outstanding this season, posting a 2.02 ERA in 58 innings, and, for now, is the favorite to see save opportunities.
