It's the closest the Rangers have been to first place in the division since they were one game back on April 18.
Texas has quietly been moving up the standings for over a month thanks to a 23-12 record since Aug. 1, which is the second-best mark in the AL during that span (the Blue Jays are 26-8).
Mets rally again over Nationals
For the second straight day, the Mets pulled off a comeback win over the Nationals in a critical three-game series in Washington D.C. The Mets now lead the second-place Nats by six games in the National League East.
With the Nationals holding a 7-1 lead entering the seventh inning, the Mets rallied for six runs against three relievers to tie the game. In the eighth, Kirk Nieuwenhuis belted a go-ahead homer and the Mets held on to win, 8-7.
The late-inning heroics overcame a rough start from Mets ace Matt Harvey, who allowed a career-high seven earned runs over 5 1/3 innings.
"That was so much fun to watch," Harvey said. "I was frustrated with my own performance, but overall we won the game. And that's huge."
The Pirates own a two-game lead for the top NL Wild Card over the Cubs.
• The Cardinals saw their magic number to clinch a postseason berth reduced to nine, by virtue of the Nationals' loss to the Mets. The Cards could clinch a playoff spot as early as Sunday, and would be the first team to do so.
Meanwhile, the loss dropped the Angels 4 1/2 games behind the Rangers for the second AL Wild Card.
