Jansen saved Saturday's 5-2 win against Colorado, pitching a 1-2-3 ninth with a strikeout.
Jansen entered in the ninth with a three-run lead and made quick work of the heart of Colorado's order for his 29th save of the season. The 33-year-old has now surrendered just one run across his last 12 innings and has saves in six of his last seven appearances.
