NEW YORK (AP) โ€” Rookie slugger Ryan Mountcastle hit a two-run homer, Rio Ruiz added a three-run shot and the Baltimore Orioles hit four homers and cruised to an 11-2 victory over the New York Mets on Tuesday night.

The Orioles won their fourth straight and improved to 20-21, moving within a half-game of the slumping Yankees for the second wild-card spot.

โ€œThe energy throughout the day has been good,โ€ Ruiz said. โ€œWe hope to continue that the last few weeks in September.โ€

D.J. Stewart also homered for the third straight game after hitting three homers in Baltimoreโ€™s weekend series over the Yankees. Cedric Mullins had an RBI triple as the Orioles won for the sixth time in eight games.

Pat Valaika hit a solo homer and had an RBI infield single that the Mets challenged and could not get overturned in the fifth. Valaikaโ€™s hit occurred just before Ruiz lined a 3-1 sinker from Robert Gsellman into the right field seats to turn the game into a rout.

Jose Iglesias capped the scoring with an RBI single in the eighth.

Baltimore tied season highs for homers and runs and scored double-digit runs for the third time this season.

โ€œUnselfish, battle type of at-bats,โ€ Orioles manager Brandon Hyde said. โ€œNext guy up mentality. Nice for these guys to see thatโ€™s winning baseball. Iโ€™m just really happy with everybodyโ€™s effort tonight.โ€

Jake Marisnick and Jeff McNeil homered for the Mets, who lost for the eighth time in 12 games and absorbed one of their most lopsided losses of the season.

โ€œWe got to play better than we did tonight and take care of business,โ€ Marisnick said.

Baltimore left-hander John Means (1-3) rebounded nicely from one of his worst starts of the season, allowing one run on three hits in a season-high six innings. Means struck out five, walked one and threw a season-high 97 pitches.

Means faced the Mets for the second straight time but was significantly better six days after allowing four runs and eight hits last week in Baltimore.

โ€œHonestly this is the first time I felt like myself,โ€ Means said. โ€œA slight mentality change is what caused me to have really everything going tonight. Yeah, this is the best Iโ€™ve felt all year. Itโ€™s nice to get back there.โ€

Michael Wacha (1-3) allowed five runs (four earned) on seven hits in four innings. He has allowed 11 runs in three starts since returning from a three-week injured list stint due to right shoulder inflammation and the Mets have a 6.34 ERA from their starting pitchers in games not started by Jacob deGrom.

โ€œI got to be better with my pitches, pitch selection and executing pitches where they need to be,โ€ Wacha said. โ€œYou look back at the start tonight, a couple of changeups got left over the middle of the plate, elevated and they didnโ€™t miss them."

The Orioles took a 2-0 lead on Stewartโ€™s drive into the second deck in right field in the second inning and went up 4-1 an inning later when Mountcastle hit his fourth homer since being called up.

Valaika opened the fourth by reaching on Marisnickโ€™s fielding error in center. After Marisnickโ€™s misplay, the Orioles went up 5-1 on Mullinsโ€™ third career triple.
