CINCINNATI - Just when it looked like the Reds might drag themselves out of the gutter, they fell right back in.
The hitters took another night off with Tyler Mahle on the mound and left the rookie to sink or swim on his own Saturday night. Mahle did himself in with two gopher balls in an otherwise promising start, and the Miami Marlins beat up reliever Austin Price to put the finishing touches on a 6-0 win.
The Reds (8-25) were shut out for the fifth time this season and managed just four hits, two by Joey Votto, in taking their fourth loss in the last five games. Once Mahle (2-4) gave up a two-run homer in the first inning to Starlin Carto and a solo shot in the sixth to Justin Bour, it didn't matter that the Marlins (12-20) got three runs in the eighth off Price.
"I didn't really settle in," said Mahle, who surrendered just five hits in six innings. "The one pitch they got to hit they hit well, but I continued to make just average pitches."
Castro's RBI double started a three-run rally in the eighth. Brian Anderson singled home two more.
Marlins starter Caleb Smith gave his third straight impressive performancet striking out seven Reds in 5 1/3 innings and allowing just three hits.
Miami got Smith (2-3) from the Yankees in the offseason as part of a deal for right-hander Michael King. The left-hander has been stingy in his last three starts, allowing only two runs and seven hits in 18 2/3 innings with 26 strikeouts.
"I feel like a kid," said Smith, who made two starts and seven relief appearances for New York last season. "It's awesome."
Smith had a few rough starts in April. Marlins coaches talked to him about throwing more strikes and challenging hitters, and it's made the difference.
"He was OK in spring training," manager Don Mattingly said. "We thought he deserved an opportunity to see what he could do. It was his time. We had an opportunity to find out whether he'd be a starter or a reliever. Right now, he's a starter."
Castro's RBI double started a three-run rally in the eighth. Brian Anderson singled home two more.
Miami's J.T. Realmuto went 0 for 3 and was hit by a pitch, ending a 12-game hitting streak that was the longest active in the NL.
WHAT'S UP DOC?
Mattingly received an honorary Doctor of Humane Letters degree from the University of Evansville. Evansville President Thomas A. Kazee traveled to Milwaukee when the Marlins played there last month to privately present the degree, which was announced Saturday as part of the school's commencement.
Mattingly grew up in Evansville, and two brothers attended the school. He went into the Yankees' organization after high school.
"I'm excited about it," Mattingly said. "I had two brothers go to that school, so since I was a kid I would go to their games."
CASTRO'S PLACE
Castro's first homer in the majors also came at Great American Ball Park. He homered in his first big league plate appearance off Homer Bailey on May 7, 2010, with the Cubs.
SLIGHT DELAY
The game started 10 minutes late because of rain, which fell steadily through the early innings.
SCOOTER BACK
Second baseman Scooter Gennett was back in the Reds' lineup after being limited to pinch-hitting in the previous four games because of a sore throwing shoulder. He went 0 for 3 with pair of strikeouts.
TRAINER'S ROOM
Reds: RHP Michael Lorenzen threw 40 pitches without problem at the Reds' spring training complex. He has been sidelined since the start of the season with a strained pitching shoulder. He's scheduled to throw batting practice on Monday.
UP NEXT
Marlins: Dan Straily (0-0) makes his second start since returning from an inflamed right forearm. He has lost both of his career appearances against his former team.
Reds: LHP Brandon Finnegan (0-2) has been the victim of blown saves in each of his last two starts. The Reds have lost all of his four starts this season.
