Pitching has carried the Mariners much of the way this season in their push for the playoffs, but Seattle went on the offensive with three solo home runs Friday night in a 4-2 victory over the free-falling A’s. The series-opening win puts the Mariners in a tie for the second AL Wild Card berth with 16 games to go.

On Friday, for the first time in more than 14 months, the Mets beat the Nationals at Citi Field with a 4-3 win. Two hits — a bases-clearing double by Travis d’Arnaud and an RBI double by Juan Lagares — drove in all four Mets runs.

Lyle Overbay delivered a walk-off single in the ninth inning following a pair of intentional walks to give the Brewers a 3-2 victory over Cincinnati on Friday night, keeping Milwaukee a game and a half out of the second National League Wild Card spot and four games back in the NL Central.

Rookie Allen Webster logged six quality innings, while Mookie Betts’ RBI single fueled a three-run third to help the Red Sox earn a 4-2 win over the Royals on Friday night at Kauffman Stadium.

Six different players knocked in runs for the Padres, including Rene Rivera, who hit his 10th home run on Friday night, as the Padres defeated the D-backs, 6-5, at Chase Field.

With Friday’s 7-2 win over the Indians, led by J.D. Martinez’s four RBIs and David Price’s brilliant start, the Tigers took a half-game lead in the American League Central.

Gerrit Cole went six strong innings and the Bucs got three hits apiece from Josh Harrison and Jordy Mercer en route to a 7-3 win over the Cubs on Friday at PNC Park.

Robinson Chirinos lined a two-out single to center field in the eighth inning to drive home the winning run and give the Rangers a 2-1 win over the Braves on Friday night at Globe Life Park.

Chase Headley has rejoined the Yankees in Baltimore and been cleared to play after tests conducted by a neurologist in New York on Friday came back negative. The infielder, whose tests checked for concussion symptoms, was struck in the face by a fastball during Thursday’s 5-4 victory over the Rays at Yankee Stadium.

While the 3-1 final score Friday night would indicate a pitchers’ duel, Philadelphia’s victory over Miami was actually more a display of the two teams’ consistent prowess on the mound with danger lingering. In the end, it was a hit without a runner in scoring position — a two-run blast by Cody Asche in the 10th inning — that proved to be the difference in the game.

Dodgers pitcher Hyun-Jin Ryu left Friday night’s series opener with the Giants after one inning because of left shoulder irritation.

By the time a long Friday was over, the Orioles had two more wins against the Yankees — their first doubleheader sweep against their nemesis since 1984 — including a 5-0 victory in front of 43,727 in the nightcap, and had trimmed their magic number to five with a 10th win against New York in 13 tries.

The A’s have been on the wrong end of several one-run games this month, all of them without closer Sean Doolittle. So his return to the bullpen Friday for the start of a crucial three-game series in Seattle provided relief in more ways than one.

With a steal of second base Friday night at Miller Park, Todd Frazier became a rarity in Reds history. Frazier is only the third third baseman to become a 20-20 man — with at least 20 home runs and 20 stolen bases.

Brandon Belt was back in the Giants’ clubhouse Friday afternoon, and the first baseman was back to his usual entertaining ways. Perhaps the good mood should come as no surprise, since Belt was cleared to resume baseball activities on Thursday, after being put through a full workout by specialist Michael “Micky” Collins in Pittsburgh.

Michael Wacha, who recently returned from a right shoulder injury, will not make his scheduled start for the Cardinals against the Rockies on Sunday.

Brewers manager Ron Roenicke and pitcher Mike Fiers reiterated Friday that the pitch that hit slugger Giancarlo Stanton and caused severe facial injuries to the Marlins star was an accident, and both of them have tried to get in touch with Miami manager Mike Redmond.
