MIAMI -- Martin Prado went 3-for-3 with a walk and two RBIs as the Miami Marlins defeated the Cincinnati Reds 4-2 on Saturday afternoon at Marlins Park.

Adam Conley (6-5) picked up the win, allowing two runs in 5 2/3 innings for the Marlins (46-41). A.J. Ramos posted his 27th save of the season by pitching a scoreless ninth.

John Lamb (1-6), who struck out a career-high nine batters, many of them with curveballs in the range of 67 mph, took the loss for the Reds (32-56).

The Marlins will try for a three-game sweep on Sunday, the last action before the All-Star break.

Miami scored in the first inning. Leadoff batter J.T. Realmuto singled and advanced to third when Prado doubled off the glove of third baseman Eugenio Suarez. Realmuto scored when Reds catcher Ramon Cabrera, who was expecting a fastball, was crossed up by a Lamb breaking pitch. It was ruled a passed ball.

Cincinnati tied the score 1-1 in the second on Adam Duvall's 23rd homer of the season. Hitting the ball on a line, Duvall crushed an 83 mph breaking pitch from Conley that was left up and over the plate.

The Reds took a 2-1 lead in the fourth. Newly named All-Star Jay Bruce doubled to right and scored on a two-out, opposite-field single by Brandon Phillips, who is playing with a fracture in his left hand.

Miami regained the lead at 3-2 in the fifth. Conley got a hit off Lamb's glove, Realmuto singled and Prado doubled to the warning track in right on a fly ball that was overrun by Bruce.

The Marlins increased their lead to 4-2 in the eighth on a broken-bat single to center by Giancarlo Stanton.

Miami outfielder Ichiro Suzuki, who owns 2,990 major-league hits, grounded out to the pitcher later in the eighth as a pinch-hitter.
