CINCINNATI (AP) This was one really bad bounce for the St. Louis Cardinals.
Adam Duvall's drive to right for Cincinnati in the eighth inning bounced off the top of the wall and went over for a tiebreaking two-run homer, sending the Cardinals to a 4-2 loss to the Reds on Saturday in the completion of a game suspended Friday by rain.
Eugenio Suarez singled with one out before Duvall connected on a 1-0 pitch from former Reds reliever Jonathan Broxton (2-5). Duvall's third homer since joining the Reds on Aug. 31 and sent the NL Central-leading Cardinals to their fifth loss in six games.
''There are times when every decision is right and times when you have to work harder,'' St. Louis manager Mike Matheny said. ''This is one of those times when we have to work harder.''
All three of Duvall's hits since joining Cincinnati have been homers.
''It was down,'' Broxton said of the pitch. ''When I was playing here, I didn't see any balls go out like that. It kept going and going and going. It was weird.''
Duvall's strength impressed manager Bryan Price.
''Wow, think of the kind of strength that takes to hit one like that that carries out that way,'' he said.
J.J. Hoover (8-1) pitched the eighth for the win. Aroldis Chapman struck out the side to earn his 30th save.
Heavy rain forced Friday's game to be suspended in the top of the eighth inning. Pinch-runner Pete Kozma was on first base after Suarez dropped a routine popup to shortstop on the last play before umpires called for the tarp.
The teams waited out the 17th rain delay at Great American Ball Park for an hour and seven minutes before it was suspended. It was Cincinnati's second suspended game this season and first at home. Three home games have been rained out.
Reds first baseman Joey Votto struck out and walked three times. He received a two-game suspension on Friday for an altercation with umpire Bill Welke, but will keep playing until his appeal is heard.
Michael Lorenzen gave up two runs in five innings in the 42nd consecutive start by a rookie for the Reds, passing the 1902 Cardinals for the major league record. The Reds have gone with an all-rookie rotation since trading Johnny Cueto and Mike Leake in July.
Billy Hamilton got the Reds off to a nice start in the first. He reached on a bunt single, swiped second and advanced to third on catcher Yadier Molina's wild throw for an error. Hamilton then scored on Brandon Phillips' infield single.
Cincinnati catcher Ramon Cabrera added his first major league homer in the second.
The Cardinals repeatedly wasted scoring opportunities, stranding runners in scoring position during the first three innings. Also, Jon Jay was thrown out at third base while trying to stretch a double with no outs in the fourth.
Pitcher John Lackey had an RBI groundout in the second, and Greg Garcia homered in the fourth. Lackey allowed seven hits in seven innings and matched his season high with 10 strikeouts.
Cincinnati Vice Mayor David Mann presented career hits leader Pete Rose with a key to the city and proclaimed Saturday ''Pete Rose Day.'' Friday was the 30th anniversary of Rose's record-setting hit. A Rose bobblehead helped attract a sellout crowd.
Cardinals C Cody Stanley was suspended for 80 games for testing positive for a performance-enhancing substance.
Stanley, 26, spent most of this season at Triple-A Memphis, but was promoted to St. Louis when major league rosters expanded on Sept. 1. It is the seventh suspension announced this year under the big league program.
Major League Baseball said Stanley tested positive for dehydrochlormethyltestosterone. The suspension is effective immediately.

Reds: Hamilton's two stolen bases were his first since Aug. 18. He was activated from the disabled list on Tuesday after missing 19 games with a sprained right shoulder.
Cardinals: Lance Lynn (11-9) is coming off one of his worst starts. He lasted only 2 1-3 innings and gave up six runs - matching his season high - during a 9-0 loss to the Cubs. He Is 7-3 career against the Reds with a 3.51 ERA.
