Janssen had a stretch of converting 15 consecutive save opportunities until Chicago's Adam Dunn led off the ninth inning of Monday night's game with a solo homer to left.
That tied the game at 2, but Janssen was able to salvage the inning by retiring the next three batters to help set up an eventual 3-2 victory in 11 innings.
"The big thing right there was we wanted to give the team a chance to win it and keep it tied as best I could," Janssen said. "Quick memory because [Alex] Rios can do some damage as well and every guy in that lineup can, so to get out of there with I guess just giving up one was what I was trying to do."
During Janssen's streak of consecutive saves, he allowed a total of just seven baserunners over 15 2/3 innings. He faced the minimum and 11 of those outings and the 15 straight saves is the sixth-longest stretch in club history.
Not a bad start to Janssen's career as a closer, but it will be his ability to bounce back from a bad outing that will be most telling. That's something Janssen feels he'll be equipped to do because of his long tenure as a setup man.
"I think in your younger days you would have been a little more frustrated but with this job, you have to have a quick memory," Janssen said. "It's pitch to pitch, it's hitter to hitter.
"You hate to blow a game ever but on the bright side, it didn't cost the team a loss and we were able to come back. All in all, it's still a good day, not personally, but for the team."
