PHOENIX - Mat Latos matched his career high with 13 strikeouts and the Cincinnati Reds salvaged the finale of their three-game series in Arizona with a 4-2 victory over the Diamondbacks on Sunday.
Shin-Soo Choo hit a leadoff home run and Brandon Phillips added a two-run shot in the first inning off Randall Delgado (0-1).
That was plenty of offense for Latos (7-1), who allowed a run on six hits with one walk in 7 2-3 innings.
Latos, coming off his first loss in 21 starts, didn't strike anyone out in the first two innings, then fanned 13 over the next 5 2-3.
After blowing a save in Cincinnati's 4-3 loss on Saturday, Aroldis Chapman gave up a run in a shaky ninth but still got his 19th save.
The loss snapped Arizona's four-game winning streak.
In the ninth, Chapman got the first two batters to bounce out to shortstop before Cliff Pennington singled and went to second on defensive indifference. Pinch-hitter Wil Nieves singled in Pennington to cut it to 4-2.
A wild pitch moved Nieves to second, then Chapman hit Gerardo Parra in the right forearm with a 100 mph fastball.
Pitching coach Bryan Price went to the mound to settle down Chapman, and the left-hander got Willie Bloomquist to pop out to center to end the game.
Latos fanned six in a row in the third and fourth -- Delgado, Parra, Bloomquist, Paul Goldschmidt, Miguel Montero and Jason Kubel -- all swinging. Of Latos' season-high 110 pitches, 79 were strikes.
The Reds jumped on Delgado from the start.
Choo hit an 0-2 pitch into the swimming pool area in right field, his fourth leadoff homer of the season and ninth of his career. Zach Cozart followed with a double, then after Joey Votto struck out looking, Phillips' homer to left made it 3-0.
Choo and Phillips each have 11 home runs this season.
Cincinnati added an unearned run in the second. Xavier Paul led off with a double, then Pennington bobbled Devin Mesoraco's grounder down the third base line for an error. Latos sacrificed the runners to second and third, and after Choo walked to load the bases, Cozart brought Paul home with a sacrifice fly to the wall in left-center.
Delgado went five innings, allowing four runs -- three earned -- and six hits.
The right-hander, who came to Arizona from Atlanta as part of the Justin Upton trade, made his second start since being called up from Triple-A Reno to bolster a rotation depleted by the 10-game suspension of Ian Kennedy and a shoulder injury to Brandon McCarthy.
The Diamondbacks broke through in the eighth when Parra doubled with one out, then advanced to third on Bloomquist's groundout. Goldschmidt drew a two-out walk and Montero singled Parra home to make it 4-1, maintaining Arizona's status as the only team in the majors not to be shut out this season.
Left-hander Manny Parra relieved Latos and got Jason Kubel to ground out to first to end the inning.
The Diamondbacks had runners at first and third with one out in the fifth but Latos struck out pinch-hitter Eric Hinske and Parra to end the threat.
A.J. Pollock threw out Votto trying to advance to second on Phillips' deep fly to center, ending the Reds' fifth.
