BOSTON -- Nathan Eovaldi continues to look sharp in Summer Camp, and he fired four solid innings on the main diamond at Fenway Park on Tuesday. He threw another inning indoors after it rained, for a total of nearly 85 pitches.

Eovaldi will pitch one more intrasquad game on Sunday as a final tuneup for the start of the regular season. Given Rodriguez’s absence from camp, it seems all but inevitable that Eovaldi will start on Opening Day.

“I haven’t said anything to him yet,” Roenicke said. “That conversation will probably happen in the next day or two, and you guys can figure out the numbers there. But I haven’t said anything to Nate yet.”

Eovaldi doesn’t think he will need to be on any type of innings restriction when the season starts.

“I feel like I’m ready now,” Eovaldi said. “Before we came back with [Summer Camp], I was throwing a lot. I was five, six innings, around 100 pitches each time. It’s almost like a nice little break and build back up.

“With hitters in the box, we’re going to have the adrenaline and everything like that. But I’ve had my normal soreness, and nothing new has popped up. I feel like I’m ready.”

Lefties progressing
Without question, the Red Sox’s pitching staff will look a lot better when their three key left-handers recovering from COVID-19 -- Eduardo Rodriguez, Darwinzon Hernandez and Josh Taylor -- return to action.

“We're starting to see good things in the testing,” said manager Ron Roenicke. “I don't want to say exactly what that is, but there's a progression -- you start seeing some good things with the antibodies and the other testing, and we're starting to see those now.”

All three pitchers will need to test negative for COVID-19 twice more than 24 hours apart before being cleared to return to the team. In the meantime, they are all doing their best to keep their arms in shape.

“Eddie has continued to throw. He has a net in his backyard. He can actually throw innings back there -- although he doesn't have a catcher -- but he can work out there,” Roenicke said. “I know Darwinzon has been playing catch. I’m not sure what JT has been doing. Once you're stuck in a room, it’s kind of hard to get out.

“JT hasn't been able to come here; he may take a little bit longer. Hopefully Darwinzon and Eddie will be a little bit farther along, and we'll see how JT is and how soon we can ramp him up.”

Dugout and bullpen distancing
One of the unique sights of Summer Camp has been Red Sox players sitting on the suite level while watching their teammates participate in drills or games, since the lockers have all been moved from the regular clubhouse for this season.

However, Roenicke said the players won’t be able to space out in suites during regular-season games.

“I don't think they're going to be allowed up in their suites during the season. So far, that's what I've heard,” Roenicke said. “So we've got plans to spread people out.”

The Red Sox continue to get creative in making the most out of Fenway Park’s limited available space.

“There's another dugout that they wanted to build in between our dugout and home plate, along the line there. Whether it will be tents or whether it will be a structure, I know they need to get going on that,” Roenicke said. “Then in the bullpen, same thing, there's another structure that we've talked about behind bullpen that both the visiting and home team can go [to]. And some taller chairs, so we can have more guys in the bullpen.

“From what I understand, we can have nine players in our dugout [and] three coaches, which means we're probably going to have to alternate the hitting coach and the pitching coach during when we hit and when we're on defense. That's the last I've heard; that's what we plan to do.”
