Dodgers relief pitcher Kenley Jansen worked a perfect ninth inning in Los Angeles' 1-0 win over the Rockies on Sunday.
Jansen needed 12 pitches to get through the inning, including a 3-pitch strikeout of Wilin Rosario to end the game.
"I felt pumped up, both times out," Jansen said to MLB.com. "Today, it was my first time in the ninth, with a one-run lead, when you can't make a mistake. I felt great, felt pumped up, and did my job."
Jansen, who was named the team's closer by manager Don Mattingly earlier in the week, maintained his perfect 0.00 ERA in two innings of work.
"It's nice to have Kenley [for the ninth]. He's established, one of the tops in the league. You have that rock at the end of the game," Mattingly said.
