Little side note on the Braves:
Since September 1st, 2010 the Braves have played 2,473 games* and two people have been their starting 1B-man in 93.2% of them (2,304). As you might have guessed, 9/1/10 is the day of FFF's ML debut**, he was 11 days shy of turning 21. Now Frederick did get his days off, particularly early on, and appeared often as a PH only that September. He also was the starting 3rd baseman 16 times in his career and had his share of missed time due to injuries (118 games played in '15, 117 games played in '17, etc.). So all of the missed 1B games are his since his direct replacement, Matt Olson, quite famously has a consecutive games played streak which started before he ever got to Atlanta and continues to date. Tonight will be his 767th consecutive game as a Brave, all of them starts at 1B (played a few innings in RF).
It would be tough, particularly in today's game, to find two guys covering that high a percentage of starts at one position with no gap in between them. And it would be especially tough to top their combined (just w/Atlanta) 451 HRs and 645 doubles. Olson is 32 (turns 33 in March) and is signed through 2029 with a team option for 2030 so the legacy of this tandem has a ways to go yet.
* actually, I calculated this a couple days ago and I'm not going to do it again ... and, besides, it changes the math just a minuscule amount and the point not at all
** Against the Mets!!! He went 0/3 with a GiDP and was PH'd for late in the game. Braves won 4 - 1. Not a single other person who played in that game is still active although it was Craig Kimbrel's rookie season so he pitched both that year and this one just not in that game. One from that game is in the HoF (Billy Wagner, Chipper was injured and didn't play), one has managed (David Ross), and at least one is deceased (Pedro Feliciano). The pitching matchup was Mike Pelfrey vs Tommy Hanson
