Carl Yastrzemski - 3 times
The Red Sox legends keep popping up on this list as Carl Yastrzemski was another three-time achiever here. Yaz's finest season was 1967 where he got the Triple Crown including 44 home runs and 121 RBI and, unsurprisingly, won MVP that year. The power side of the equation is what normally kept Yaz from doing this more, but three times is still incredibly impressive.
JD Martinez - 2 times
Hopefully fans years down the road appreciate all the good that JD Martinez brought in his time with Boston. Martinez posted back-to-back 35/100 seasons in 2018 and 2019 before seeing his number dip a bit the last few seasons he was with the Red Sox. The guy could just flat out hit.
Tony Armas - 2 times
Tony Armas is not exactly a household name in the game of baseball as he had a pretty short peak, bounced around a little, and turned back into a pumpkin the last third of his career or so. However, his first two years with Boston were great as he averaged 40 homers and 115 RBI in 1983 and 1984. He would never eclipse 23 homers or 64 RBI the rest of his career, but those were a couple fun seasons.
We have made it to the one-time entrants on the list starting with Dick Stuart. Stuart's 1963 season with Boston was one of the better offensive seasons in franchise history as he had 42 homers and 118 RBI in 157 games. Sadly, Stuart's career tailed off quickly after that season and he was out of baseball after the 1966 season except for one return attempt with the Angels in 1969.
As good as Fred Lynn was, it is mildly surprising that he didn't manage to pull off more 35/100 seasons, but we have to remember that he was only with the Red Sox from 1974-1980 and he never really put up big time power numbers. However, his 1979 season with Boston was astonishing as he hit 39 homers and drove in 122 runs while leading the league in batting average, on-base percentage, and slugging that year.
Next up is Vern Stephens whose 1949 season puts his name on this list. Vern hit 39 homers and drove in a whopping 159 runs that year and his three-year peak in 1948-1950 was pretty remarkable. However, he started to decline in 1951 and never came close to being the guy he was before retiring after the 1955 season.
