Nick Gonzales' single in the eighth inning drove in the go-ahead run as the Pittsburgh Pirates continued their mid-season surge with Monday's 2-1 victory over the St. Louis Cardinals.

Gonzales hit that scored All-Star Bryan Reynolds snapped a 1-1 tie and helped give Pittsburgh its seventh win in eight games as it pushes for a play-off spot in the National League. The Pirates, who last reached the post-season in 2015, sit a half-game behind the New York Mets for the NL's final wild card spot.

Pittsburgh also moved within a game of St. Louis for the second wild card. 

Reynolds led off the bottom of the eighth with a single and advanced to second on a wild pitch by St. Louis reliever John King. Two batters later, Gonzales hit a slow grounder that got through the infield to score Reynolds for a 2-1 Pittsburgh lead.

David Bednar then held the Cardinals scoreless in the ninth to earn his 18th save of the season. Aroldis Chapman received the win with one scoreless inning in relief of Mitch Keller, who allowed just one run on six hits in a seven-inning no-decision.

The Cardinals also got a solid outing from their starter, as Andre Pallante yielded just one run and three hits through six innings.

Nolan Gorman accounted for St. Louis' lone run by hitting a solo homer off Keller in the fifth inning that tied the score at 1-1. The Pirates had gone ahead in the third when Andrew McCutchen doubled and later scored on Oneil Cruz's single. 

Witt just misses cycle in Royals' rout of Diamondbacks

Bobby Witt Jr. finished a single short of hitting for the cycle and had one of three Kansas City home runs as the Royals rolled to a 10-4 victory over the Arizona Diamondbacks to extend their winning streak to four games.

Witt tripled in the first inning, doubled in the third and delivered a three-run homer in the fourth that gave the Royals an 8-3 lead. The All-Star shortstop was hit by a pitch and flied out in his final two at-bats, though, to narrowly miss becoming the first Kansas City player to record a cycle since Hall of Famer George Brett in 1990.

Salvador Perez had a go-ahead two-run homer in the third inning and Hunter Renfroe later added a solo shot as part of the Royals' 15-hit attack. Vinnie Pasquantino and Kyle Isbel each collected three hits, with Isbel driving in two runs and Perez three.

Arizona had taken a 3-1 lead when Ketel Marte followed Alek Thomas' RBI double in the top of the third with a two-run homer off Cole Ragans. The Royals countered with three runs in their half of the inning, however, to quickly move back ahead.

Witt started the rally with a lead-off double and scored on Pasquantino's single before Perez launched Arizona starter Yilber Diaz's pitch over the center field wall for a 4-3 Kansas City edge.

The Royals then extended the margin with four runs in the fourth.

Isbel doubled in Maikel Garcia and Adam Frazier followed with an infield single to chase Diaz. Witt then greeted Miguel Castro with a home run on the reliever's first pitch to put Arizona at a five-run deficit.

Renfroe's solo homer in the fifth increased the lead to 9-3.  Perez drove in Witt with the Royals' final run with a sacrifice fly in the sixth.

Ragans (7-6) shook off his early troubles to work six innings while allowing three runs on five hits and striking out six.

Diaz (1-1), making his third MLB start, was tagged for seven runs in three-plus innings.

Isbel previously knocked in Kansas City's first run with a second-inning single. The Diamondbacks managed a late run in the eighth when Christian Walker doubled and later scored on Eugenio Suarez's sac fly.

Ober pitches Twins past struggling Phillies

Bailey Ober bounced back strongly after allowing an early home run to Bryce Harper to lead the Minnesota Twins to a 7-2 win over the struggling Philadelphia Phillies in the opener of a three-game series.

After giving up hits to three of the game's first four batters, including Harper's two-run homer, Ober (9-5) yielded just one more hit over the remainder of his seven-inning stint to improve to 4-1 over his last six starts. The right-hander retired 17 of the final 18 batters he faced.

Manuel Margot led Minnesota offensively with two hits, including a two-run single that gave the Twins a 3-2 lead in the fifth inning. Willi Castro also knocked in two runs to help Minnesota snap a three-game losing streak, while Carlos Santana and Max Kepler each had two hits and an RBI.

The Phillies still own the majors' best record at 63-37 but have now lost four of their last five games.

After Castro's third-inning single plated Diego Castillo to trim Philadelphia's lead to 2-1, the Twins struck twice more in the fifth to forge ahead.

Kepler led off the bottom of the fifth with a single and Castillo followed with a ground-rule double to put two on for Margot, who sent both runners home with a go-ahead single to right off Philadelphia All-Star Ranger Suarez.

Suarez (10-5) lost his third straight start after surrendering three runs and seven hits over 5 1/3 innings.

The Twins extended their lead in the seventh when Ryan Jeffers doubled and later crossed the plate on a Santana double, then put the game out of reach with three runs in the eighth.

Kepler followed a Trevor Larnach double with a run-scoring single to put Minnesota up 5-2, and the Twins later loaded the bases before scoring twice more on a walk to Castro and a wild pitch from reliever Yunior Marte.

Cole Sands worked the final two innings for Minnesota to notch his third save of the season.
