Home runs from J.T. Realmuto and Kyle Schwarber backed six solid innings from Aaron Nola as the Philadelphia Phillies clinched their first National League East title since 2011 with Monday's 6-2 win over the Chicago Cubs.

The Phillies also received a run-scoring single from Nick Castellanos to enhance their chances of earning one of the NL's top two seeds and a first-round bye for the upcoming playoffs. Philadelphia (93-64) now trails the Los Angeles Dodgers by a half-game for the majors' best record with less than a week remaining in the regular season.

Nola (13-8) scattered seven hits and struck out seven while allowing just two runs. The steady veteran pitcher held the Cubs scoreless through the first six innings of play as the Phillies gradually built a 6-0 lead.

Realmuto opened the scoring with his 14th homer of the season, a two-run shot off Caleb Kilian in the second inning. Schwarber made it 3-0 an inning later with a lead-off homer that gave him 100 runs batted in for a second straight season.

The Phillies added another run off Kilian in the third when Trea Turner followed Schwarber's blast with a double and later scored on Castellanos' single.

Bryce Harper led off the bottom of the fifth with a double and eventually crossed the plate on an error by Chicago second baseman Nico Hoerner to increase the margin to 5-0. The Phillies scored again in the sixth when Brandon Marsh drew a walk, advanced to third on Johan Rojas' single and came home on a double-play grounder off the bat of Schwarber.

Nola was removed after surrendering back-to-back doubles by Isaac Paredes and Hoerner that got the Cubs on the board. Hoerner later scored on a groundout for the game's final run.

Kilian (0-1) allowed all six Philadelphia runs - five earned - and eight hits across 5 2/3 innings. 

Mariners put Astros' AL West title plans on hold

The Seattle Mariners got seven scoreless innings from Bryce Miller and two runs batted in from Julio Rodriguez to prevent the Houston Astros from clinching the American League West with Monday's 6-1 win.

Rodriguez went 3 for 5 to lead a 13-hit attack that closed Seattle within 1 1/2 games of the co-holders of the AL's final two wild-card spots, the Kansas City Royals and Detroit Tigers.

The Mariners still have a faint chance of winning the AL West, though Houston needs to win just one of this series' two remaining games to claim its fourth straight division title.

Miller (12-8) continued a strong finish to his season by yielding just two hits and a pair of walks. The right-hander is now 2-0 with a 0.72 ERA over his last four starts.

Hunter Brown (11-9) allowed just one run while striking out eight over six innings for Houston, but issued two walks in the third inning that led to Seattle taking a 1-0 lead on Cal Raleigh's single that plated Victor Robles.

The Mariners added on in the seventh after loading the bases on singles by Justin Turner and J.P. Crawford and a walk to Dylan Moore. Two batters later, Rodriguez singled to center to drive in Turner for a 2-0 advantage.

Seattle loaded the bases again in the eighth on three consecutive singles before Turner brought in Raleigh with a sacrifice fly. Jorge Polanco followed with a run-scoring double to stretch the margin to 4-0.

Jason Heyward finally got Houston on the board with a solo home run in the eighth, but the Mariners scored twice more in the ninth to put the game out of reach. 

Back-to-back doubles by Robles and Rodriguez increased the lead to 5-1 before Rodriguez scored on Randy Arozarena's double.

Giants drop Diamondbacks back in NL wild card standings

The San Francisco Giants hit three home runs, including an inside-the-park shot from Matt Chapman, to come through with a 6-3 win over Arizona that knocked the Diamondbacks out of a tie for the NL's second wild card.

Casey Schmitt and Michael Conforto also homered to help the Giants to a fourth straight win. Chapman finished 2 for 3 and drove in three runs, while San Francisco starter Hayden Birdsong (5-5) struck out six while holding the Diamondbacks to two runs in five innings.

Arizona fell a half-game behind the New York Mets in the standings and now holds a 1 1/2-game lead on the Atlanta Braves for the final NL wild card. The Braves and Mets begin a pivotal three-game series in Atlanta on Tuesday.

The Diamondbacks had an early 1-0 lead after consecutive doubles by Geraldo Perdomo and Joc Pederson in the first inning, but the Giants went ahead with three runs in the third off Eduardo Rodriguez.

After Heliot Ramos singled and scored on Jerar Encarnacion's double, Chapman drove a pitch off the center field wall and sprinted around the bases for the first inside-the-park homer by a Giants' player since Denard Span in 2017.

Christian Walker drove in Corbin Carroll with a double in the bottom of the third to pull Arizona within 3-2, but Schmitt's solo homer in the fourth restored the Giants' two-run advantage.

Conforto went deep an inning later to increase the lead to 5-2, then doubled in the seventh before crossing the plate on a Chapman triple.

Arizona got a run back in its half of the seventh when Jose Herrera doubled and scored on Perdomo's single. The Diamondbacks failed to score thereafter, though, with Ryan Walker throwing a perfect ninth for San Francisco to record his 10th save.

Rodriguez (3-4) struck out eight in 4 2/3 innings but was tagged for five runs on seven hits.
