Four pitches doomed Wade Miley and the Arizona Diamondbacks on Sunday. Malik Jefferson Jersey . All four left the ballpark -- the most home runs Miley has allowed in his career -- and the Diamondbacks lost to the Cincinnati Reds 4-3. "I need to make better pitches," he said. "Two inches more down and maybe it is not a homer to left. Who knows?" Cincinnati led 3-0 after homers by Zack Cozart and Todd Frazier in the third and by Ryan Ludwick in the fourth. Arizona tied it with a three-run fourth, then in the fifth Chris Heiseys second home run of the season put the Reds on top for good. "Were really not a home-run hitting team," Frazier said, "but when we do, we win." Converted reliever Alfredo Simon (7-3) gave up three runs in 6 1-3 innings. Aroldis Chapman hit 103 mph on the Chase Field radar gun in a perfect ninth, overpowering three batters not long ago in the minor leagues and earning his seventh save in eight opportunities. Miley struck out nine with no walks in six innings of another tough loss. He fanned a career-high 12 in his previous start, getting no decision in a 4-3 loss to San Diego. "I feel like I am throwing the ball well right now, but things arent going my way," he said. "Just got to keep grinding through it." David Peralta singled twice in his major league debut for the Diamondbacks. The Reds won their last three and four of five to finish their trip out West at 4-3. Arizona wrapped up a 3-4 homestand. "I thought we swung the bats pretty well today," Diamondbacks manager Kirk Gibson said. "We hit a lot of balls and they made some plays on us. It just wasnt meant to be and that is frustrating. "At the end they just shut us down. Chapman come in throwing 102, 103, it is pretty tough duty." Cozart hit the first pitch of the third inning into the left- field seats, his second home run of the season, to make it 1-0. After two outs, Frazier hit Mileys 1-0 pitch into the same area, his team-high 10th homer -- and the Reds led 2-0. Cincinnati made it 3-0 in the fourth when, with two outs, Ludwick homered -- also to left. Arizona broke a streak of 15 scoreless innings in the fourth. Paul Goldschmidt drew a one-out walk and when Miguel Montero lined Simons 3-0 pitch off the wall in right-centre for a double. Montero moved to third on Martin Prados single then scored on Eric Chavezs sacrifice fly to cut the lead to 3-2. Peralta, just up from Double-A Mobile to replace the injured A.J. Pollock, singled to centre, putting runners at first and third, and Ender Inciarte singled in the tying run. Peralta led off the seventh with a single and Inciarte flied out to deep right. That was it for Simon. Gerardo Parras two-out single off Sam LeCure put runners first and third but Cliff Pennington lined out to right to end the threat. Prado singled with two outs off Jonathan Broxton in the eighth and took second on a passed ball. But Chavez popped out to end the inning. Broxton has allowed one run in 18 appearances this season. Cincinnati loaded the bases with one out in the ninth on an error, single and hit batter against Oliver Perez. Addison Reed came on to get Heisey to pop out and Frazier flied out.
