PITTSBURGH (AP) - Gregory Polanco homered, Charlie Morton continued his effective pitching at home and the Pittsburgh Pirates won for the fifth time in six games, 5-1 over the Arizona Diamondbacks on Wednesday night.
Polanco, a highly touted rookie who has reached safely in 19 of 21 major league games, had a double, a walk and his third home run for Pittsburgh, which clinched its fourth consecutive series victory.
Polanco's line-drive shot to right off Chase Anderson in the second inning gave the Pirates a 3-0 lead.

Paul Goldschmidt went 3 for 4 with a run for the Diamondbacks, who have lost three straight.
Andrew McCutchen of the Pirates, who earlier in the day was named NL player of the month for June, did not play the field in the ninth inning. He fouled a ball off his foot and winced in pain in the eighth, but continued his at-bat and singled. There was no immediate word if McCutchen was injured or if it was a precaution.
Pittsburgh (44-40) has won nine of 11 and moved a season-best four games over .500.
Morton (5-9) limited Arizona to one run, five hits and three walks in six innings to lower his ERA at PNC Park to 2.13.
Morton has worked into the sixth inning during all eight of his home starts this season and has allowed four earned runs over 33 2-3 innings in his past five starts at home.
Justin Wilson, Tony Watson and Mark Melancon each worked a scoreless inning for Pittsburgh. Run-scoring hits by Starling Marte and McCutchen in the eighth inning eliminated a save opportunity for Melancon.
Russell Martin went 2 for 3 with a walk for the Pirates.
Anderson (5-4) allowed 11 baserunners and did not get out of the fourth inning.
Last-place Arizona had three errors.
Reds 3, Padres 0
SAN DIEGO (AP) - Tyson Ross threw a three-hitter for his first career shutout and Rene Rivera hit a three-run single off big league ERA leader Johnny Cueto as the San Diego Padres beat the Cincinnati Reds for their first three-game sweep since September.
The Padres, who tied their season high with their fourth straight win, hadn't swept a series since Sept. 6-8 against Colorado.
Ross (7-8) was dominating in throwing his first complete game in 55 career starts. He struck out nine and walked none.
With the bases loaded and two outs in the first, Rivera hit a blooper to the gap that hit off the heel of the glove of diving center fielder Billy Hamilton to give San Diego a 3-0 lead.
Cueto (8-6) came in with the best ERA in the majors, 1.88. It rose to 1.99.
Nationals 4, Rockies 3
WASHINGTON (AP) - After a replay review, Ian Desmond's solo homer provided the go-ahead run and the Washington Nationals rallied from a three-run deficit for 4-3 win over the Colorado Rockies, sweeping the three-game series.
Jayson Werth also homered for Washington, which has won a season-high five straight.
Right-hander Matt Belisle (2-4) came on to face Desmond with one out in the seventh. Desmond's hit appeared to bounce off the top of the wall in right center, then off the railing in front of the first row and onto the field.
He ended up on third, but after a review that took 3:42, Desmond was given his 15th homer.
Washington's Doug Fister (7-2) allowed three runs on seven hits over seven innings.
Rafael Soriano pitched the ninth for his 20th save.
Michael McKenry hit a three-run homer for Colorado.
Braves 3, Mets 1
ATLANTA (AP) - Chris Johnson hit a three-run double, Julio Teheran pitched seven strong innings and the Atlanta Braves beat the New York Mets to complete a three-game sweep.
The Braves extended their season-best winning streak to seven games. The Mets have lost four straight and seven of their last eight games and are a season-worst 11 games below .500.
Teheran (8-5) gave up four hits and three walks while lowering his ERA to 2.29. Jordan Walden pitched a perfect ninth for his third save as closer Craig Kimbrel received a night off.
The NL East-leading Braves remain one-half game ahead of Washington.
New York rookie Jacob deGrom (1-5) was undone by his season-long control problems in a long first inning.
Marlins 5, Phillies 0
MIAMI (AP) - Casey McGehee reached base three times, doubled home a run and scored another, helping the Miami Marlins to a victory over the Philadelphia Phillies, who lost their sixth game in a row.
Tom Koehler (6-6) allowed three hits in six innings and earned his first victory since June 4. Three relievers completed a five-hitter.
Jarrod Saltalamacchia hit a two-run homer in the ninth, his eighth. The Marlins, who leads the majors in home victories, clinched the three-game series and improved to 27-21 at Marlins Park.
Cole Hamels (2-5) gave up three runs and needed 97 pitches to get through five innings, ending his career-best 10-game streak of pitching at least seven innings. Hamels, a victim of poor run support all season, remained winless since June 6.
The Phillies were shut out for the 11th time, which is tied for second-most in the majors.
