BOSTON — Monday night was Ian Seymour’s chance to celebrate.

All of his hard work, and the help and support he got from family and friends along the way, as he made his major-league debut, throwing two scoreless and hitless innings at Fenway Park, where he used to attend games as a kid, to lead the Rays to a hard-fought win.

This,” he said in the clubhouse afterward, “is probably the best day of my whole life.”

But Tuesday morning was a reminder of reality.

Seymour, 26, had joined the Rays on Sunday to provide a fresh arm capable of covering multiple innings to help a bullpen taxed by heavy use.

Having thrown 28 pitches Monday, and being on a starter’s once-every-sixth-day or so throwing schedule, Seymour wasn’t going to be of further help to the Rays for at least several days.

So he was optioned back to Triple-A Durham.

“Look, it’s tough anytime you send somebody down. And certainly with Ian, for his debut up here,” manager Kevin Cash said. “I think this morning, when I talked to him, he’s probably still deservedly so on cloud nine and really excited.

“I just expressed the appreciation and just how impressed we were with the way that he controlled the environment and controlled his own head space. Because that can be pretty daunting.”

The Rays recalled Mason Englert, who had won the final bullpen spot out of spring training, then was sent down in early May

In 11 games for the Rays, Englert had a 6.00 ERA, allowing 12 earned runs over 18 innings, with a concerning 23 hits. He struck out 18 and walked only four.

“(He) did some good things before he was on option,” Cash said. “I think it’s obvious we probably needed some coverage after the way we’ve used the bullpen the last few days.”

Rehab report

Infielder/outfielder Richie Palacios, who has played just one game between a spring broken finger and a right knee sprain, started a rehab assignment Tuesday with the Florida Complex League team, going 1-for-4 and playing leftfield. … Infielder Ha-Seong Kim (right shoulder surgery recovery) went into play for Triple-A Durham on Tuesday hitting .206 overall through 10 games, though 5-for-his-last 11. His 20-day rehab assignment is slated to end Saturday.

About Monday night

While there was plenty of drama and excitement in Monday’s 10-8, 11-inning win that took nearly four hours, there were also some ugly numbers: 23 men left on base, 15 walks, four errors, three batters hit by pitches and a botched pop fly that led to a weird infield fly ruling. … It was the Rays’ first time scoring 10 or more runs with two or fewer extra-base hits since Aug. 12, 2019, at San Diego.
