Can you make out any relevance from the number of Ballpark FX opportunities and results as to what card a player has?

Example
Jim Gentile after 84 games has gone 5 for 21 in ballpark FX singles and 5 for 24 in ballpark FX HR chances.

Name B P GB-FB GIDP GWBI SI Opp HR Opp Hit Pit
Gentile, J. L 1B 144-126 9 4 5 21 5 24 180 185

his stats and then adjusted for getting a 50/50 ballpark FX results 11 for 21 singles and 12 for 24 HRs
Name AB R H 2B 3B HR RBI BB SO BA OBP SLG OPS
Gentile, Jim 332 47 82 9 3 18 61 26 66 .247 .302 .455 .756
Gentile adjusted 332 47 95 9 3 25 61 26 66 .286 .338 .557 .895


He has not been injured so I can't tell but I believe he is on his 1962 or 1963 card ....any thoughts??

If all the ballpark homer opportunities for said batter came off of the pitcher's card and get recorded on the stat page for both the pitcher and the hitter, then the analysis you are doing of "projecting" doesn't offer many clues. My approach would be to analyze if the ballpark homerun opportunities are unusually low for a given power hitter. If so, then, I'd be looking for a card that has pure homers and no #. If the ballpark homerun opportunities are unusually high for a non-power hitter, then, I'd rule out a card that has pure homers and no #. Either way, I haven't done much to pinpoint the right card.

So, in summary, the conclusion you have a 62 or 63 card could have been reached just as easily without examining ballpark homer results.

What is you home ballpark for lefties -- that is where he is playing 1/2 his games. Then are there a lot of pitcher parks in your division and league with low lefty homerun and single numbers. What you can maybe adjust for is 50% of the chances in your home ballpark and 50% in the rest of the league's ballparks, with double weight for the ballparks in your division.

good thought...Home park is Memorial which is 1-8 for BP HR FX vs. LHB
here are the BP HR FX vs LHB for the stadiums in my division: 1-1, 1-8, 1-1,

In the other 2 divisions it goes like this 1-4, 1-17, 1-1, 1-8, 1-17, 1-1, 1-10, 1-19

SO a large percentage of games played will be in parks that diminish a LHB's power ...

thanks for the input

Based on his relatively low walk rate, his fly ball/ground ball ratio, the number of double plays he's hit into, and R/L HR rate, I would guess he's on '62. There are two spots on that card where he can hit "natural" home runs to account for the non BP HR's he's hit, '62 is the only year where his HR rate is higher vs LHP than RHP, and the middle column is largely ground balls which might explain the gb/fb ratio.

I'm guessing the number of ballpark HR opportunities he's had has been somewhat pitcher assisted. I had him on '61 in the 2015 MT and he only had 25 BP HR opps the entire season(10/25) but still launched 51 HR's.

So that's my best guess, which is largely irrelevant as I see you dropped him, but it's still fun to speculate.

yes, I evaluated him to be on the 62 card as well so I dropped him...
