Martinez gave up a hit and struck out one in a scoreless ninth inning Tuesday to record his 18th save of the season in a 1-0 win over the Giants.
The right-hander has now strung together seven straight scoreless appearances, posting an 11:3 K:BB through 7.1 innings over that stretch, and he hasn't blown a save in almost a month. Martinez now sports a 3.15 ERA and 44:15 K:BB through 40 innings on the year, and he'll need to stay locked in down the stretch if the Cards are going to secure another NL Central crown.
