Cal Raleigh homered twice and drove in a career-high six runs to lead a 15-hit outburst by the scorching Seattle Mariners, who rolled to a 14-2 rout of the Chicago White Sox on Monday to extend their winning streak to seven games.
Raleigh went 3 for 5 with three runs scored and accounted for half of the Mariners' four homers as Seattle won for the 15th time in 18 games. Teoscar Hernandez and Dominic Canzone added solo shots with Hernandez finishing with two hits and three RBIs.
The Mariners' surge has moved them past the Toronto Blue Jays for the AL's final wild card and within two games of slumping Texas for first place in the American League West. The Rangers twice blew late leads in a 4-3, 11-inning loss to the Arizona Diamondbacks on Monday.
Seattle also received strong pitching from ace Luis Castillo, who struck out nine while holding the White Sox to one run in seven innings to win his third consecutive start.
Chicago starter Touki Toussaint was tagged for five first-inning runs and seven overall before being removed with none out in the fifth.
Diamondbacks rally twice late to stun struggling Rangers
Tommy Pham's walkoff two-run double in the 11th inning capped a second late rally that catapulted the resurgent Arizona Diamondbacks to a stunning 4-3 win over the reeling Texas Rangers to open a key two-game series.
After forcing extra innings on Ketel Marte's solo homer in the ninth inning, the Diamondbacks trailed 3-2 with two outs in the 11th when Pham drove Rangers closer Will Smith's pitch into the gap in right-center field to plate Marte and Geraldo Perdomo and give Arizona an improbable eighth win in 10 games.
The Diamondbacks closed within a half-game of the San Francisco Giants for the National League's final wild card spot.
Texas, meanwhile, was dealt a season-high fifth straight loss and saw its lead over second-place Houston in the AL West reduced to 1 1/2 games after the Astros recorded a 9-4 win over the Boston Red Sox on Monday.
The Rangers got eight shutout innings from Jordan Montgomery and a solo homer from Adolis Garcia to carry a 1-0 lead into the bottom of the ninth, but couldn't hold it as Marte homered off reliever Aroldis Chapman with one out.
Texas regained the upper hand on Nathaniel Lowe's two-run double in the top of the 11th, but Smith intentionally walked Marte to put two on in the bottom of the frame before Perdomo delivered an RBI double to trim the lead to 3-2.
Montgomery yielded just four hits and a walk while striking out six in a tough-luck no-decision.
Harper's inside-the-park home run highlights Phillies' rout of Giants
The Philadelphia Phillies hit four home runs, including an inside-the-park shot from Bryce Harper, in a 10-4 victory over the San Francisco Giants that opened a three-game series between National League playoff contenders.
Edmundo Sosa, Alec Bohm and Kyle Schwarber also went deep to back seven strong innings from Aaron Nola as the Phillies strengthened their hold on the NL's top wild card spot. The defending NL champions now own a 2 1/2-game advantage on the Chicago Cubs, who moved past San Francisco by a half-game for the No. 2 wild card with Monday's 7-6 win over the Detroit Tigers.
Sosa gave Philadelphia a 3-1 lead with a two-run homer off Sean Manaea in the second inning, and the Phillies increased the margin with a two-run fifth highlighted by Harper's second career inside-the-park homer. The two-time NL MVP raced around the bases to extend the advantage to 5-2 before Bryson Stott doubled home Bohm for a four-run cushion.
Schwarber's 33rd homer of the season followed Johan Rojas' two-run triple in the seventh to give Philadelphia a commanding 10-2 lead.
Nola surrendered solo homers to Joc Pederson and Lamonte Wade Jr. over his first three innings before shutting out the Gians over the remainder of his stint. The standout right-hander scattered seven hits and one walk while striking out five.
