Jansen struck out one in a perfect ninth inning during Friday's 5-4 extra-innings loss to the Diamondbacks.
With the score tied 4-4 and a save situation off the table at home, Jansen worked the top of the ninth and rang up Alex Avila for his first strikeout of the season. The right-hander looked healthy this spring and, assuming his heart issues are behind him, Jansen should once again be one of the top closers in baseball.
