FORT MYERS – We’re four games into spring training, and Michael Chavis has three three-run home runs.

It’s early, but it’s also fair to say the 23-year-old who hit 31 homers two years ago between Single and Double A has some serious pop.

“I think it will be a major part of my game,” said Chavis, who homered over the Green Monster in the fourth inning of the Red Sox’ 7-6, split-squad loss to Baltimore. “When I was at the lower levels still learning how to play professional baseball, the power thing wasn’t my main approach, and it’s not even that now. I was trying to learn my swing, learn how a baseball swing itself worked.”

The lessons have sunk in.

“In regards to the power coming last, I wasn’t sitting there in Greenville like, ‘My power’s going to come, guys, don’t worry,'” Chavis said. “I know what I’m capable of doing. I’m not out there trying to hit for power or anything like that. It’s just one of those things that shows up.”

Manager Alex Cora enjoyed the show. He had heard plenty of good things about the club’s first pick of the 2014 draft, but because of an injury last spring and then his performance-enhancing drug suspension, had not laid eyes on him.

“I heard a lot of stuff, I saw some videos, but that’s just videos,” Cora said. “He has a very good idea what he’s doing. He prepares, he’s paying attention to the game, you can see he works on his moves. In batting practice, he understands what he wants to do.

“He can hit, he can hit.

Mookie Betts added: “It’s been great, great to watch, great to actually see him play, and we’ll just see how things go.”

E-ROD SHAKY

Eduardo Rodriguez started and pitched two innings, allowing two runs on three hits, one the first of two home runs hit by Chance Sisco.

“OK, velocity was good,” Cora said. “The 0-2 breaking ball to Cisco, usually he doesn’t make those mistakes against lefties in-season, so he gave up some hits with two strikes. Obviously for his first outing, he’s in one piece, so we’re good.”

Expectations are high for Rodriguez.

“We have a lot for Eddie. He expects a lot of himself as well, so it’s fun,” Jackie Bradley Jr. said. “I love to hear him come in here and talking smack to everybody. That shows that he has a lot of confidence and he’s ready.”

EARLY SIGN

Bradley, batting first, connected for a leadoff home run to center. It was his second home run of the spring. Rather than dismiss it as too early, Bradley thought it was a telling sign.

“I’m reading into everything this spring training just because I’ve been working on a lot of things this offseason, so I’ve just been trying to focus on making sure I’m doing everything mechanically the right way,” Bradley said. He seemed just as pleased as the single he hooked into right field in the fourth.

“My last at-bat today I feel like was a prime example. Normally that’s a ball I would roll over, and I was able to get the path correctly and was able to get it over the infielder’s head,” he said. “So far, so good. Been able to get my feet wet a little bit and work on some things and kind of stick with that.”

BETTS DEBUTS

Betts’ first game this spring was a quiet one. He didn’t catch a ball and was 0-for-3 with a pair of groundouts and a strikeout.

“It was Day 1, nothing to it, first game,” said Betts, who is not worried about expectations as he comes off his AL MVP campaign.

“I’m sure (expectations are) pretty big, but I can only do what I can do. We have a great team, we have a lot of great players here, so it’s not all on one guy.” …

In his debut, reliever Tyler Thornburg gave up the other home run to Sisco. Thornburg allowed two runs on two hits with one strikeout and no walks.

“He knows his stuff, not going to make a big deal out of this, it was only one inning,” Cora said. “When he’s ready, mechanical-wise, he can get people out.” …

In the split-squad game against the Rays in Port Charlotte, the Red Sox lost, 5-4. Rafael Devers hit a home run, as did Tony Renda. Andrew Benintendi was1-for-3 with a double. …

The Nationals will start perennial Cy Young candidate Max Scherzer here today, with Hector Velazquez starting for the Red Sox.
