Right-hander Jamie Callahan will follow Johnson in the first game. Manager John Farrell plans to have "as many pitchers as possible" throw one inning each over the first three games.
Henry Owens will start the team's Grapefruit League opener on Friday against the Mets. Roenis Elias will get the ball on Saturday, facing the Twins.
Rain, but no worries
It wasn't unexpected that the Red Sox would have to deal with the fickle South Florida weather at some point this spring. It is, however, unfortunate that it had to happen on the last full day of workouts before games begin on Thursday.
Tarps covered the infield of JetBlue Park on Wednesday as a steady rain put a damper on the day's workout schedule. Hitters were confined to the indoor batting cages at Fenway South, and all fieldwork was canceled. Pitchers who were scheduled to throw their regular bullpen sessions also used the indoor cages.
"The priority at this point in camp is getting our repetition for our pitchers and get them on the mound for the appropriate number of pitches for a bullpen session," Farrell said. "The only thing we were unable to accomplish today was the live hitting."
Like all Major League teams, the Red Sox were already dealing with an accelerated workout schedule to accommodate the World Baseball Classic tournament this spring.
So far, so good for Pablo
Sandoval is excited to get back into game action on Thursday, as it's something he hasn't been able to do in nearly 11 months. He'll bat fifth against Northeastern.
"When you get up to home plate, especially having lost a year, just to get to home plate and facing a live pitcher and having a good result against them is going to feel great," Sandoval said.
