PORT CHARLOTTE, Fla. — Red Sox right-hander Rick Porcello was hit hard in Boston’s 13-5 loss to a Tampa Bay Rays split-squad on Sunday.

Porcello was charged with eight runs and 10 hits in three innings.

Porcello, who went 9-15 with a 4.92 ERA last year in his first season with Boston, struck out two and walked none.

“The results weren’t very good, but I was throwing strikes,” Porcello said. “I don’t like the line, for sure. I don’t like giving up eight runs on 10 hits. … It’s a work in progress and it’s getting there.”

Porcello allowed seven straight hits after retiring the first two batters in the second. Manager John Farrell said pulling Porcello wasn’t an option.

“If we’re talking about it when it’s the regular season, sure that’s a different story,” Farrell said, “but we’re trying to get his pitch count built up.”

Hank Conger hit a two-run homer for Tampa Bay and finished with three RBI.

Rays second baseman Logan Forsythe had his third multihit game of the spring, collecting two singles. Erasmo Ramirez allowed one run and five hits in four innings.

“(Ramirez) looks good,” Rays Manager Kevin Cash said. “He got into some jams, and they kind of singled him to death there. Sometimes you want that to happen to see how a guy responds in a spring training setting. He got out of it both times.”

Red Sox prospect Yoan Moncada made his second start of the spring and went 1 for 3 with a strikeout.

The 20-year-old Cuban infielder, who signed with Boston last March, said he is grateful the Red Sox gave him chance to play at the major league level in camp.

“It felt good to play in my second big league game and play at this level,” Moncada said through a translator.

Farrell said he has been pleased with Moncada’s maturation.

“The defensive side is a clear area of development for him,” he added, “but being in the setting and in the speed of (this) game, that’s helpful for him. There is work to be done defensively.”

NOTES: Porcello threw 52 pitches, 38 for strikes. He also threw a wild pitch that allowed a run to score. … Red Sox catcher Blake Swihart left in the fourth inning with a jaw contusion after Rays first baseman Patrick Leonard hit a foul ball into Swihart’s head gear. Farrell said Swihart passed concussion protocol testing and is day to day. … Red Sox left-hander Eduardo Rodriguez threw a long-toss session from 120 feet, and Farrell added that Rodriguez is “progressing nicely” from his knee injury. “It was another productive day for him,” Farrell said, “and we’ll get him on the mound when he’s ready for the next step.”
