On the walk, issued to Eric Hinske, Majewski blamed himself for rushing.
"My first game back in there, I wouldn't say nervous, but [I was] geeked up," Majewski said. "From now on, it's just fine-tuning it, getting things back in order and doing my job."
Shoulder inflammation caused Majewski to be ineffective last year following the controversial July trade that sent him from the Nationals to the Reds. He later disclosed that he was injured before the transaction was made, and Cincinnati eventually alleged that Washington didn't provide full disclosure.
The issue didn't go away in the opening days of Spring Training, when Majewski revealed that the shoulder soreness returned during his offseason throwing program. He's been playing catch-up ever since.
"I've been busting my [tail] as hard as I can since Feb. 3, trying to get out there and pitch without pain," Majewski said. "Regardless of what happens, if I stay down here [on the disabled list] or Triple-A, I'll keep fine-tuning it and I want to get at least one or two games in and prove to everybody that I still have some [stuff] in the tank."
More roster cuts:
The Reds trimmed four more from their spring roster on Monday morning. Infielders Mark Bellhorn and Anderson Machado, catcher Ryan Jorgensen and outfielder Dewayne Wise were reassigned to Minor League camp.
The most significant name was Bellhorn, who was given a couple of days to report to Triple-A Louisville or ask for his release. The veteran utility infielder batted .250 (10-for-40) with one home run and eight RBIs during Spring Training.
"I'm happy we were able to get him a lot of playing time," Narron said. "We got a chance to see him, and the other clubs have. A lot of times, non-roster guys don't get that kind of opportunity. He definitely had a lot of exposure this spring."
Cincinnati has 34 healthy players remaining in camp, meaning there are nine more cuts to make to get down to the 25-man limit by Opening Day on April 2.
A strained right forearm kept outfielder Chris Denorfia out for the third straight game. Denorfia, who is fighting for one of the final roster spots, is unable to throw, but he has taken swings the past couple of days.
"It's tough any time that you get hurt, but especially coming into the season," Denorfia said Monday. "It was a good time for me to build up some momentum to start the season off strong. It was kind of interrupted. I'll just have to play a little catch-up. I got plenty of at-bats already, so I'm pretty confident I'll be ready to go when I'm healthy."
Reliever Bill Bray still has discomfort in his bruised left index finger and did not throw, as originally scheduled.
Right elbow soreness has kept infielder Juan Castro from playing in the field. Castro can still hit, however.
Injured outfielder Norris Hopper, who is battling with Denorfia, had his bruised right heel removed from a protective boot. Hopper was scheduled to throw and hit.
Elizardo Ramirez (sore right shoulder) was expected to play catch on Monday.
The Nos. 1-8 slots of the Reds lineup vs. Boston was the likely group fans will see on Opening Day. It was Ryan Freel, Adam Dunn, Brandon Phillips, Ken Griffey Jr., Edwin Encarnacion, Scott Hatteberg, Alex Gonzalez and David Ross.
"Hopefully, they'll get a chance to play all this week," Narron said.
Missing from two of the past three starting lineups has been Josh Hamilton, who started a majority of this spring's games. Hamilton will likely come off the bench and fill in around the outfield and pinch-hit.
"If everybody stays healthy, that would be his role [in the regular season]," Narron said.
Hamilton pinch-hit for Livingston in the fifth and grounded out to first base off Red Sox pitcher Daisuke Matsuzaka. He finished the game 1-for-3 and has a .400 (24-for-60) average.
Monday's announced attendance of 7,663 fans set a new record at Ed Smith Stadium, breaking the old mark set in 1992, when the White Sox played there.
Kyle Lohse will get the start when the Reds face the Phillies on Tuesday at 7:05 p.m. ET in Clearwater. Lefty Jamie Moyer is scheduled to pitch for Philadelphia. Griffey Jr., who went 0-for-3 on Monday in his second game of spring, is on the travel roster to make the bus trip.
