Just adding here...rbirules wrote: ↑18 Jul 2025 08:46 amAs others have said, it's not the 321 TBs that needs to be negated, it's a fraction of them. The Coors effect (i.e. adjusting to a league average environment) takes away a lot of them. That should be self explanatory I would think.Goldfan wrote: ↑18 Jul 2025 08:02 amRBI dig into this Bichette discussion. He had 1.86CH per GAME and somehow his D negates 321 TB according to WAR. And this seems logical?rbirules wrote: ↑18 Jul 2025 07:54 amThis. It's the relativity to other positions that matters. They could have designed it with DH having a 0 positional adjustment and C having a +30 adjustment, but then they'd have to lower the baseline later, like they do when they go from RAA (runs above average) to RAR (runs above replacement), so instead they just centered all positions around 0 (some above, some below).
Next replacement level isn't 0 TB, it's a number well north of there. Dave Martinez had 0.1 fWAR that year. He was also an OF. His league adjusted batting was a little worse than Bichette's (93 wRC+ vs. 100 for Bichette). Martinez had 199 TB, he also had 65 fewer PAs, or about 10% less playing time than Bichette, so his TBs would be closer to 220 if he had the same playing time.
So that gap is now 100 TB due to park factors and bases given up defensively.
I found another near replacement level player that had a wRC+ closer to Bichette's 100 (Greg Norton, 101 wRC+ played for the White Sox). His total bases if you give him the same number of ABs as Bichette would be 251, or 70 less than Bichette. So was Coors responsible for 70 of those total bases? That doesn't seem crazy to me.
Bichette made 13 errors in 1999. For an OF how many bases do you think an average error is worth? Some might only be one, but I'd guess a fair number are two bases, or letting a runner advance an extra base or two with a throwing error. 1.5 bases per error gives us 20 TBs from that alone, and those are on balls he got to and could make a play on. Balls an OF doesn't even get to usually end up as extra base hits.
Bichette made 239 Putouts in 1233 innings in 1999. In 1998 he made 288 Putouts in 1316 innings, or a rate of 269 in 1233 innings. In 1997 he made 225 Putouts in 1090 innings, or a rate of 254 Putouts in 1233 innings. So that's 15-30 Putouts worse than the two previous years if you adjust for playing time differences. I would assume most of those missed Putouts go for extra bases especially with half your games in Coors. Using 1.5 bases per missed PO would give you 20-45 TBs.
Along with being the worst defensive player in the league in 1999, he was also one of the worst baserunners...
3rd in the league in outs on the bases with 11
XBT rate of just 34% (league average 43%)
6 SB and 6 CS
He excelled hitting with runners in scoring position. Everything else he was mostly terrible at.
