Kodai Senga had a throwback performance Saturday, but not in a positive sense.

In a reversion to the second half of last season, when the right-hander became easy work for opponents, Senga got jumped early by the A’s and couldn’t even last three innings.

Sloppy defense didn’t help and Luke Weaver imploded late, but this one was mostly on Senga in his team’s 11-6 loss at Citi Field amid plenty of boos that gave the Mets a four-game losing streak.

The Mets awoke offensively after three straight dormant games but never caught the A’s following Senga’s ugly abbreviated outing. Senga smacked his right leg in disgust with his glove as he walked toward the dugout after his removal in the third inning.

“The biggest thing was I wasn’t able to control very many pitches near the strike zone or over the plate,” Senga said through his interpreter.

Senga lasted only 2 ¹/₃ innings, surrendering seven earned runs on eight hits and two walks with three strikeouts before being removed at 72 pitches. It was a reversal from what the Mets had seen from Senga in his first two starts this season, when he was effective against the Cardinals and Giants.

“He didn’t have much, especially fastball command,” manager Carlos Mendoza said. “He kept going to that sinker, just to see if he could get back in counts or get strikes, but he just didn’t have a feel for his pitches.”

Bo Bichette ended the Mets’ scoreless drought at 17 innings with an RBI single in the first against lefty Jacob Lopez, giving the Mets a 1-0 lead.

Senga walked Denzel Clarke with the bases loaded in the second to give the A’s their first run. Lawrence Butler’s RBI fielder’s choice extended the lead to 2-1. Senga’s troubles started with consecutive singles by Jacob Wilson and Jeff McNeil to begin the inning before Carlos Cortes walked with one out to load the bases. Francisco Lindor had a defensive lapse in the inning — he was caught out of position on a grounder to Marcus Semien, costing the Mets a shot at a double play on Butler’s grounder that could have ended the inning. Semien instead ran to the base after fielding the grounder.

“I went after the ball and Marcus was there and didn’t make it to second base and we didn’t turn the double play,” Lindor said.

It continued a rough stretch for Lindor in all facets of the game – he’s batting only .167 following a 1-for-5 performance. He’s also had lapses on the bases, most recently Friday when he got caught off third base on a grounder.

“I feel like I’m locked in,” Lindor said. “I feel like I’m in the game and it just happens. I have got to be better.”

Tyler Soderstrom smashed a two-run homer against Senga in the third, following Shea Langeliers’ leadoff double. The blast was the first Senga had allowed this season. The A’s started a second rally in the inning. Wilson singled — a ball that Semien missed with a bare hand — and McNeil hit a grounder off Mark Vientos’ glove for a single. Cortes delivered the knockout blow to Senga with a three-run homer that buried the Mets in a 7-1 hole.

“It’s tough having back-to-back innings with high pitch counts,” Senga said. “But not every outing is going to be smooth sailing. Some outings are going to be tough. In a long season stuff like this is going to happen, so I want to reflect on this over the time before I go back out there, to make sure it doesn’t happen again or it’s better next time.”

Bichette’s first Mets homer cut the deficit. With Lindor aboard, Bichette hit a shot to right that just cleared the right-field fence. The two-run homer gave Bichette a team-leading nine RBIs.

Francisco Alvarez’s blast leading off the bottom of the sixth sliced the Mets’ deficit to 7-4. The homer was Alvarez’s team-leading fourth this season. Before the inning was complete, Carson Benge scored the Mets’ fifth run. Benge walked and scored on Brett Baty’s sacrifice fly following Semien’s single.

Jorge Polanco homered an inning later to pull the Mets within one run. The Mets put the tying and go-ahead runs on base before the inning was complete, but Benge and Semien were retired in succession to end the threat.

Weaver’s second straight rough performance sank the Mets in the eighth. Weaver surrendered a three-run blast to Soderstrom after Langeliers’ RBI single gave the A’s a two-run lead.
