DETROIT (AP) — Salvador Perez homered and drove in three runs as the Kansas City Royals beat the Detroit Tigers 5-1 Tuesday night.

The game was overshadowed by an afternoon announcement that Dave Dombrowski was being replaced as Detroit’s general manager by his top assistant, Al Avila. In 14 years with the Tigers, Dombrowski took one of the worst franchises in the game and took it to six postseason appearances including World Series losses in 2006 and 2012.

Detroit came into the season looking for a fifth straight AL Central title, but now trail the Royals by 12 1/2 games.

Danny Duffy (5-5) allowed one run on five hits and four walks in seven innings, only striking out two.

Justin Verlander (1-4) struggled in his ninth start of the season, allowing five runs on 10 hits in seven innings.

METS 5, MARLINS 1

MIAMI (AP) — Eric Campbell’s tiebreaking pinch single and Juan Lagares’ two-run triple highlighted a four-run eighth inning that helped send New York to a win over Miami.

Jonathan Niese (6-9) allowed one run and four hits in seven innings for the NL East-leading Mets, who won their fifth consecutive game.

Mets relievers Tyler Clippard and Jeurys Familia combined to pitch two scoreless innings to end the game.

Lucas Duda drove a ball over right fielder Cole Gillespie for a single leading off the eighth against Mike Dunn (1-5) and Travis d’Arnaud followed with a base hit. Campbell batted for Niese and hit a soft line drive into shallow left field over the outstretched glove of shortstop Adeiny Hechavarria.

Lagares’s tripled to make it 4-1 and scored on Curtis Granderson’s double.

The Marlins have lost six of seven.

NATIONALS 5, DIAMONDBACKS 4

WASHINGTON (AP) — Wilson Ramos blooped a two-run single to right with one out in the bottom of the eighth that helped Washington to a victory over Arizona.

Ryan Zimmerman led off the eighth with a walk off David Hernandez (0-2) and went to third on Jayson Werth’s double. One out later, Ramos sliced his single that snapped a 3-3 tie and scored both Zimmerman and Werth.

Drew Storen (2-0) earned the win thanks to a perfect eighth.

Jonathan Papelbon posted his 19th save of the season and his second with the Nationals, despite allowing an unearned run in the ninth. Washington snapped its four-game losing streak.

RANGERS 4, ASTROS 3

ARLINGTON, Texas (AP) — Relievers Sam Freeman and Shawn Tolleson pitched out of trouble and Texas held off Houston.

Freeman relieved Yovani Gallardo (8-9) in the sixth inning, and allowed a single and a walk to load the bases with one out. Freeman then retired Luis Valbuena and Marwin Gonzalez.

Tolleson earned his 20th save, all since May 20, despite giving up a walk and Valbuena’s second single before recording an out. Jason Castro and Jose Altuve struck out for the final two outs.

Texas erased a 2-1 deficit with three runs in the fifth against Dan Straily (0-1).

Houston’s Carlos Gomez drove in two runs with a double and a homer.

PHILLIES 6, DODGERS 2

PHILADELPHIA (AP) — Maikel Franco hit a tiebreaking grand slam in the seventh inning to spoil Jimmy Rollins’ return to Philadelphia and lead the Phillies to a victory over NL West-leading Los Angeles.

Rollins got a prolonged standing ovation in his first game in front of a crowd that rooted for the shortstop his first 15 seasons. The 2007 NL MVP finished 2 for 5.

Franco connected off reliever Joel Peralta to put resurgent Philadelphia ahead 5-1. The Phillies have the worst record (42-65) in the majors, but they are 13-3 since the All-Star break.

Jeanmar Gomez (1-2) allowed one run in 1 2-3 innings and Ken Giles got the final four outs for his third save since replacing Jonathan Papelbon. Giles struck out Rollins looking at a 100 mph fastball to leave runners on second and third in the eighth. Starter Jerome Williams allowed one run in five innings.
