Mat Latos went seven shutout innings to earn his first win of the season.

He allowed four hits, walked one and struck out four. His ERA stands at 2.14. It was 5.79 last year in April.

Jonathan Broxton bailed Latos out of trouble in the eighth. Aroldis Chapman pitched the ninth for his fourth save.

The sum total of the Reds' offense was Todd Frazier’s mammoth home run in the sixth. It landed on the deck of the steamboat in center field. The last Reds player to homer in a 1-0 victory was Sean Casey on Aug. 26, 2004, against St. Louis off Chris Carpenter.

The Reds closed the homestand 8-2. They open a four-game series in Washington tomorrow night.

The Reds got outstanding defensive plays from Shin-Soo Choo, Brandon Phillips and Zack Cozart.

Latos retired the first 10 batters he faced before Julio Borbon doubled with one out in the fourth. After Latos struck out Starlin Castro, Anthony Rizzo lined one to center. Choo ran it down just in front of the wall.

The Reds put runners on in each of the first five innings against Jeff Samardzija. The first inning was particularly frustrating. Choo led off with a single, extending his on-base streak to 21 games. With the hit-and-run on, Cozart popped up into a 4-3 double play. Joey Votto then singled, but he was thrown out stealing.

Devin Mesoraco and Latos started the third with singles. But Choo, Cozart and Votto struck out.
