CINCINNATI -- With the ball coming at nearly 100 mph, Chase Headley was merely trying to get the bat to meet it. Once that happened, the rest was automatic.
Headley hit a home run in the ninth inning off Aroldis Chapman, the first hit the hard-throwing lefty allowed since his return from being hit in the head by a line drive, and the San Diego Padres beat the Cincinnati Reds 2-1 on Tuesday night.
Headley connected on a 99 mph fastball from Chapman (0-1), who was making his second appearance since undergoing surgery after being struck in the forehead during a spring training game. He had a plate inserted above his left eye and nose.
"He's a guy that's throwing with tremendous velocity," Headley said. "So you can't try to do too much. You just try to get the barrel to it. He's one of those guys that if you're able to get the barrel to it, he really supplies some power for you."
His fourth home run made the difference and provided another indication that he has fully recovered from a strained right calf that sidelined him for much of spring training and landed him on the disabled list on April 25. He returned last Saturday and hit a three-run homer.
"I don't think he was quite hitting on all cylinders when the season started," manager Bud Black said.
Smith was the NL's most recent player of the week and extended his hitting streak to nine games, matching his career high. He's 19 for 34 during the streak.
The rest of San Diego's lowly offense didn't do much until Headley connected with two outs in the top of the ninth. The Padres came in last in the league in batting average and scoring.
Brandon Phillips had three of Cincinnati's seven hits, including an RBI single in the first inning. Cincinnati has 12 one-run losses, most in the majors.
"Those are what we're most upset about," Reds catcher Brayan Pena said. "We know we're better than that. Our starters are doing a tremendous job giving us a chance. Leake gave us more than we asked for. We couldn't hit for him today."
The Padres activated Carlos Quentin off the disabled list for the start of the series, moving their lineup closer to full strength. The outfielder missed the first 39 games with a bruised left knee. He went 3 for 18 during a minor league rehab stint and was 0 for 3 with a walk in his return.
Andrew Cashner got a no-decision despite allowing only one run over seven innings, a common theme to his season. The right-hander has pitched well, but gotten little support from his offense.
The Padres have scored only one run in the last 25 innings while he has been on the mound. They managed only one Tuesday night. Cashner gave up seven hits and one walk while striking out six.
"That changed the game," Cashner said.
Smith doubled in the fourth and scored on Jedd Gyorko's sacrifice fly that tied it at 1. The right fielder also prevented the Reds from putting together a big inning in the first.
Todd Frazier extended his hitting streak to a career-high 12 games, the longest by a Red this season.
The Padres recalled RHP Kevin Quackenbush from Triple-A El Paso. They optioned utility player Kyle Blanks to El Paso and put RHP Dale Thayer on paternity leave. ... Ian Kennedy (2-4) faces Johnny Cueto (3-2) in the second game of the series. Kennedy is 3-0 career against Cincinnati. Cueto leads the NL with a 1.43 ERA. ... C Devin Mesoraco (hamstring) and LHP Tony Cingranci (shoulder) could be activated during the Reds' upcoming trip. RHP Mat Latos, sidelined all season by knee surgery and a sore forearm, isn't expected back until the first week of June. ... The Reds haven't made an error in their past eight games, a season high. They have only 12 errors, fewest in the majors.
