BOSTON -- The window is getting smaller and smaller for Rick Porcello to be able to salvage something from the most trying season of his life.

The latest opportunity for the veteran righty was on Sunday night against the Yankees. Instead, it was a reprisal of events that have happened far too often this season.

In a 10-5 defeat, Porcello gave up a steady stream of runs -- two in three straight innings. Over four innings, Porcello was tagged for seven hits and six runs as his ERA rose to 5.83.

The American League’s Cy Young Award winner in 2016, Porcello is having a rough go of it in what could be his final weeks in a Boston uniform.

“I don’t know what else to tell you guys,” Porcello said. “I’m grinding, trying to figure it out. I don’t know what else to say. I’m doing everything I can and it’s not there. It sucks, man. This has been the toughest year of my career by far; it’s been the most disappointing, most emotional.

“I don’t have any other words to describe it besides I’m sorry for Red Sox fans that have got to watch it, I’m sorry for my teammates, the guys have been playing their [butts] off all year. It’s embarrassing to go out there every fifth day and not get it done and the only thing I can say is it’s not for a lack of effort. It sucks. I’ve been terrible and I’m sorry for that.”

The free-agent walk year has not been pretty for Porcello, who has been one of several members of the pitching staff to underperform for the defending World Series champions.

And the ramifications of the struggles of the team were felt immediately after the game, when the club revealed that it parted ways with president of baseball operations Dave Dombrowski.

With 19 games left in their season, the Red Sox are eight games back for the second Wild Card spot.

Porcello has given up five runs or more in 12 of his 29 starts.

What was the issue on Sunday?

“Fastball to Torres he tries to come in and left it inner third, Gleyber put a good swing on it,” said Red Sox manager Alex Cora. “Fourth inning, fastball in, kind of cut and stayed inner third and [Mike Tauchman] hit it out of the ballpark. Got some bad luck in certain hits but [Aaron] Judge hit the ball hard, Torres hit the ball hard. Fastball command with him. He didn’t have it.”
