Marshall has a 1.01 ERA in 32 games since May 20, with 20 hits, five walks and 27 strikeouts over 26 2/3 innings. Opponents have hit .198 in that stretch. Overall, he is 4-3 with a 2.41 ERA in 48 games.
"I feel good," Marshall said. "I feel comfortable, confident and it makes it easier when the rest of the guys in the bullpen are pitching just as well. We've had a pretty good run. This is probably the most fun I've had playing baseball. It makes it more fun when you're winning. It's a great group of guys, especially down in the bullpen."
In the previous two games against the Padres, Marshall has worked two perfect innings for a win on Tuesday, and one perfect inning in Wednesday's Reds win. His curveball has been particularly effective, and he's been able to get his sinker in the strike zone on both sides of the plate.
Marshall has been pleased with his role on the team since moving out of the closer spot.
"I just love pitching in games that are close and in games that I can give the team a chance to win," Marshall said. "Hopefully I have a chance to put up a zero in the inning I pitch and give us a chance to take a lead back. All of us are really happy with how [manager] Dusty [Baker] has managed our bullpen and the moves the front office made to get Jonathan Broxton here. It's a nice complement for guys that are doing pretty well."
