Harper went 4-for-5 with his 21st double of the season, and the Nationals beat the Mets, 5-3.
Harper has reached base safely 174 times this season (122 hits, 50 walks, two hit by pitches), which is the seventh most in the modern era for a player in his age-19 or younger season.
Harper's double gave him 46 extra-base hits, one shy of tying Conigliaro (1964) for the third most in history for any player in his age-19 or younger season. Ott (48 in '28) and Cavarretta (48 in '35) are tied for the most.
At 19 years and 331 days, Harper is the youngest player to have a four-hit game since Andruw Jones (19 years and 152 days) on Sept. 22, 1996.
Miami's Stanton hit his 34th home run of the season, matching his total from 2011. With the career-tying blast, Stanton joined Eddie Mathews, Alex Rodriguez and Albert Pujols as the only players in history to have a pair of seasons with at least 34 homers through their age-22 season. Stanton has 90 home runs in his career, and he is one shy of tying Ted Williams and Bob Horner for the sixth most for a player through his age-22 season.
Celebrating his 29th birthday, Ellsbury went 4-for-5 and ended the game with an RBI single in the bottom of the ninth, as the Red Sox defeated the Yankees, 4-3. The last Red Sox player to have at least four hits on his birthday was Carl Yastrzemski, who went 4-for-5 when he turned 37 on Aug. 22, 1976.
Lester struck out five to push his career total to 1,044, giving him the most strikeouts in Red Sox history for a southpaw. Bruce Hurst had been the franchise's previous leader with 1,043.
In the Orioles' 9-2 victory over the Rays, shortstop J.J. Hardy hit a pair of homers to reach 21 for the season. Hardy, who hit 30 home runs in 2011, is the fourth shortstop in Browns/Orioles history with back-to-back 20-homer seasons. Cal Ripken had nine straight, from 1983-91, Vern Stephens had three straight from '43-45 and Miguel Tejada hit 20 in three straight seasons from 2004-06.
The Orioles' victory over the Rays -- coupled with the Yankees loss to the Red Sox -- moved Baltimore back into a tie with New York for first place in the American League East. Tampa Bay is two games back in the division.
The A's beat the Angels, 6-5, to capture their 11th consecutive victory on the road and stay within three games of the Rangers in the AL West. The road winning streak is the longest for any team this season, the longest for any team since the 2003 Mariners won 13 games in a row, and the longest for the franchise since the 1981 A's won 11 in a row. The Major League record for consecutive road wins in a season is 17, shared by the '16 Giants and '84 Tigers.
Oakland's Brandon Moss went 1-for-3 with a home run, giving him 18 bombs in 221 plate appearances this season. His home run percentage is 8.14. Two A's players with at least 200 plate appearances have ended a season with a percentage that robust: Mark McGwire (twice) and Foxx (once).
Washington's Zimmerman extended his streak of games with at least one RBI to eight, with a first-inning sac fly. Zimmerman's streak is tied for the longest in franchise history. Other players with eight-game RBI streaks for the Expos/Nats are Moises Alou (1993), Larry Walker ('93), Alou again ('94) and Vladimir Guerrero ('98).
Fister (seven innings, two hits, two runs) improved to 7-2 with a 2.49 ERA since the All-Star break as the Tigers defeated the White Sox, 5-3. With the victory, Detroit moved to within two games of Chicago for first place in the AL Central.
Weeks tripled and homered in a 2-for-4 night at the plate, and the Brewers defeated the Braves, 5-0. In 57 games in the second half of the season, Weeks has 24 extra-base hits. In the first half, he had 25 extra-base hits in 81 contests.
San Francisco Giants
Despite being outhit, 17-12, the Giants defeated the Rockies, 9-8. Before this victory, the Giants hadn't won a nine-inning game while allowing that many hits since Aug. 21, 1996, when they surrendered 17 hits to the Mets but still won, 12-11.
Ian Kennedy (7 1/3 innings, four hits) and two relievers combined on a five-hit shutout and the Diamondbacks defeated the Dodgers, 1-0. Kennedy was relieved by Brad Ziegler, who faced one batter and induced a double play. In 58 2/3 innings this season, Ziegler has allowed six doubles, a triple and no home runs, and has coaxed 17 double plays.
Ziegler last allowed a home run on June 30, 2010, giving him a streak of 159 consecutive appearances without allowing a homer. The streak, which has covered 140 2/3 innings, is the longest since Greg Minton went 178 appearances without allowing one from June 1, 1979, through May 1, 1982.
Ziegler's 17 double plays are the most for a full-time relief pitcher since Jeremy Affeldt produced 18 of them in 2009.
National League Wild Card
Victories by the Phillies and Brewers -- in combination with losses by the Braves, Cardinals, Dodgers and Pirates -- tightened things up in the NL Wild Card race. The Braves (81-62) and Cardinals (75-67) still occupy the two slots, with the four other teams all within four games of that second position. Los Angeles is a game behind, the Pirates are 2 1/2 back, and the Brewers and Phillies are four games out. The Braves are 11-9 in their past 20 games, the Cardinals are 9-11, the Dodgers are 7-13, the Pirates are 5-15, the Phillies are 14-6 and the Brewers are 15-5.
