ST. LOUIS -- The St. Louis Cardinals are finding new ways to get walk-off wins.
The walk-off victory was the second in two nights for the Cardinals, who won for the fifth time in six games and remained 2 1/2 games behind Milwaukee in the NL Central.
Jhonny Peralta's RBI single in the 10th inning Monday provided St. Louis with a thrilling last-at-bat triumph.
Matt Holliday drew a leadoff walk to start Tuesday's winning rally. He advanced to third on Matt Adams' single. After Peter Bourjos ran for Holliday, Peralta walked to load the bases. Hoover (1-10) then plunked Jay to force in Bourjos with the winning run.
"It's not like you hope to get hit by a pitch every time," Jay said. "But I'll take it."
St. Louis got its sixth walk-off win of the season. The Cardinals also posted consecutive wins in such fashion July 7-8 against Pittsburgh.
The Reds lost in walk-off fashion for the third time in the last four games. They are a season-high 10 games out of first place.
"(Two walk-offs) in a row isn't fun," Cincinnati third baseman Todd Frazier said. "It's crazy, I've never been around something like that. I never want to see it again."
"Call it whatever you want to call it, but we're just playing better baseball right now," Descalso said. "We've got down the last couple nights and we've come back. That's always a good sign."
Reliever Pat Neshek (6-0) pitched a scoreless ninth inning.
Frazier put the Reds in front 2-1, with a two-run homer in the fourth. It was his 21st home run of the season, but first since July 20.
Cincinnati starter Alfredo Simon gave up three runs and eight hits over 5 1/3 innings. He struck out two and walked one.
St. Louis starter John Lackey gave up four runs, two earned, in six innings. He struck out seven and walked one.
Cincinnati scored twice in the sixth on a bases-loaded double by former Cardinals outfielder Ryan Ludwick. Errors by Holliday and Matt Carpenter and a walk set the stage for Ludwick's hit, which pushed the lead to 4-1.
But the Reds' taxed bullpen was unable to hold the lead.
"Short starts have bit us on the tail this road trip," Cincinnati manager Bryan Price said. "It blows up the bullpen."
Peralta homered in the sixth to cut the deficit to 4-2. It was Peralta's 17th home run of the season, setting the single-season mark for a St. Louis shortstop. Jay and Oscar Taveras followed with hits before pinch-hitter Shane Robinson singled off reliever Sam LeCure to bring the Cardinals to 4-3.
"I feel like the last two nights have felt like playoff games," Adams said.
St. Louis took a 1-0 lead on a run-scoring single by Holliday in the third.
Reds: Closer Aroldis Chapman was unavailable Tuesday for the second night in a row with what manager Bryan Price called an, "achy," shoulder. The reliever is listed as day to day by the Reds training staff. Chapman has 26 saves in 28 chances. He walked four successive batters on Sunday in Colorado.
Cardinals: INF Mark Ellis was put on the 15-day disabled list with a left oblique strain. Ellis, who is hitting .192 with 12 RBI, last played on Tuesday. INF Greg Garcia was recalled from Triple-A Memphis in time for Tuesday's contest. Garcia was hitting .273 with 40 RBI in 103 games for the Redbirds.
JAY KEEPS ROLLING
Jay extended his hitting streak to 11 games with a single in the second, the first of two hits. He is 15 for 31 during the run and reached base four times Tuesday.
Reds: RHP Johnny Cueto (15-6, 2.06) will start the final game of the three-game set. Cueto is 7-0 with a 2.24 ERA over his last eight starts. His seven-game winning streak is a career high.
Cardinals: RHP Lance Lynn (13-8, 2.91) will make his team-leading 26th start of the season. He is 5-1 lifetime against the Reds
