CINCINNATI (AP) — The Pittsburgh Pirates overcame a nine-run deficit for the first time in their 133-season history as Luis Rivas tied a career-high with five RBIs in a 13-12 victory on Saturday night that dealt a staggering blow to the Cincinnati Reds’ playoff hopes.

Cincinnati, which dropped 2 1/2 games back for the NL’s last wild card berth, opened a 9-0 lead with three runs in the first, five in the second and one in the third, then allowed 13 unanswered runs. The Reds attempted to rally but stranded the potential tying run at third base in the ninth.

Pittsburgh had overcome eight-run deficits four times, the last when the Pirates trailed Houston 8-0 in the second inning of a an 11-8 win on July 15, 1994.

The Reds, who have lost four straight, squandered a nine-run lead for the first time since a 10-9 defeat at Milwaukee on April 28, 2004. This was the biggest blown lead in the major leagues this season, topping Seattle’s 7-0 advantage in a 14-9 loss at the Chicago Cubs on April 11.

Reds rookie Christian Encarnacion-Strand, Tyler Stephenson and TJ Friedl all homered off Bailey Fatter, who allowed eight runs and nine hits in two innings. Friedl hit a drive into the right-field corner that Joshua Palacios couldn’t come up with and wound up with the Reds’ first inside-the-park homer since Jay Bruce at the New York Mets on June 15, 2012.

Spencer Steer’s RBI double off Kyle Nicolas boosted the lead to 9-0 in the third.

Held hitless for three innings, Pittsburgh started its comeback on Rivas’ RBI single in the fourth off against Connor Phillips. Ji Hwan Bae and Palacios had run-scoring singles in a five-run sixth and Bryan Reynolds hit a three-run homer against Alex Ríos.

Rivas greeted Lucas Sims with a three-run double in the seventh that tied the score 9-9, and the Pirates opened a 13-9 lead in the eighth against Reds closer Alexis Díaz (9-6) when Jack Suwinski and Rivas hit run-scoring singles and Bae followed with a two-run double. Right fielder Stuart Fairchild saved a run when he threw out Ke’Bryan Hayes at the plate trying to score from second on Jared Triolo’s single.

Nick Martini hit into a run-scoring forceout in the eighth and Encarnacion-Strand followed with an RBI single against Colin Selby. With two on, Bae made a diving backhand stop on Stephenson’s grounder, stepped on second and threw to first for an inning-ending double play.

On a night each team had 16 hits, José Hernández (1-1) got the final out of the seventh in his first major league win.

Pinch-hitter Joey Votto singled off rookie Carmen Mlodzinski leading off the ninth on a ball that took a bad hop over Bae, Friedl doubled and pinch-hitter Jake Fraley hit an RBI groundout that cut the Reds’ deficit to one.

Rookie Elly De La Cruz struck out on an inside sweeper in an 11-pitch at-bat, and India flied out to center.
