"Josh Johnson closed out the winningest April in Marlins history Saturday night with another one of his typical, dominating pitching performances.

He threw 117 pitches over seven scoreless innings, gave up five hits, struck out six and walked two along the way, shrinking his major league-best ERA to 0.88.

But it wasn't enough.

For the second start in a row, the Marlins bullpen let a lead handed over to them by Johnson wilt away. Four outs away from a second consecutive loss, the Reds rallied from a three-run deficit to pullout a 4-3 win in front of a loud, sellout crowd of 40,286 at Great American Ball Park.

And it stung.

"[Johnson] pitched his butt off [Saturday]," said Mike Dunn, who gave up the game-winning hit to former Marlins World Series hero Edgar Renteria with two outs and the bases loaded in the 10th. "He was amazing. He went out there like he has been every start. We blew it for him."

The Marlins, who scored a first-inning run on an Omar Infante RBI single and two more in the eighth on a Wes Helms bases-loaded double off Aroldis Chapman, came in with the best bullpen ERA in the majors (2.10).

But up 3-0 with two outs in the eighth, they couldn't avoid blowing their fourth save in 14 chances this season.

After left-handed specialist Randy Choate struck out Jay Bruce and Joey Votto to start the inning, manager Edwin Rodriguez elected to bring in right-hander Edward Mujica to pitch to Brandon Phillips.

The Reds jumped all over Mujica. Philips doubled, then Jonny Gomes, Miguel Cairo and Ramon Hernandez all singled to make it 3-2.

Ryan Webb came on in relief. But he couldn't protect the lead either. Paul Janish's hard roller through the hole into left was bobbled by Scott Cousins and his throw home was too late to get Cairo."
