Chris, love the shots, I shoot with a D3s as well looking to up my glass this year, luckily the coach lets me hang out in the dugout so the 200mm is still within range, just bought a TC1.4 will try that out next week. I shoot in Seattle where as you can see they play in the rain, turf infields usually overcast, first shots of this season. These were shot, Manual, 1/500, 200mm, ISO 3200, typically I shoot baseball min 1/1000 in decent weather, but don't like to get above ISO 3200.
Your Exif says 420mm what lens were you using for these they are tack sharp! Nice Work!!
I also like #2 assume this was shot from behind/ through the fence?
