While true, I think even you would have to say Rafaela has exceeded expectations on offense, this year. (maybe not on D.)
He had serious issues with high K rates and high chase rates all through the minors, and we knew they must have been working with him to improve in that area.
I also think we have to take into account his awful start to the season, at the plate.
.463 on APR 26
.597 as late as JUN 5!
Here is one way to breakdown his season:
.463 in 97 PAs to start the season
.710 from 4/27 to 6/5 (125 PAs) & Under .600 at the 222 PA mark of the season is a significant sample size
.824 in his last 197 PAs, which is a bigger sample size than the two above. It's not definitive, but it is pretty good and growing longer.
Another view:
.586 first 203 PAs
.814 last 216 PAs
We don't know what he will do, going forward, and he will have to make adjustments to the adjustments league pitchers make on approaching him.
It's easy to say, "He needs to learn to be disciplined and not chase so many bad pitches," but I'm not so sure that is the solutions. For one thing, we are not sure he can do that without messing up his swing and mindset. I'm not comparing him to Devers, here, but many wanted him to change his approach, too, and of course all batters have made adjustments over their careers, but do not think he has made any major adjustments to his approach. He still swings at some pitches outside the zone, and some go for homers. I'm just not sure "change" is always a solution.
That being said, I wish he could/would be more selective, but if that changes his approach, radically, it might not be for the good.
I'd be happy with .700 and fewer unforced errors from Rafaela, going forward. .725 to .750 is now above the mean in MLB, and would be very nice from him. .750+ would be great.
