I haven’t played the outfield in a while I was just converted to a 1st baseman.
Anyways here’s what I have for you. If you’re playing LF or RF the ball will slice towards the line when hit towards the line and in the gaps it’ll be a little straighter. Make sure you always start back because you don’t want that ball sailing over your head for extra bases. Try to get to everything, if you don’t get to a ball then make sure you keep it in front of you.
Learn a crows hop, that will really help your arm strength and always be sure to hit your cutoff in the head, you want to throw it to where it will get a one hop or no hop to the bag but make sure your cutoff man can get to it if he needs to. Remember no extra bases.
Hitting wise, if you’re struggling with soft toss odds are you’re pulling your head, try to go oppo and watch the ball into your bat, practice it a lot so that it becomes natural to do so and you can do it without thinking about it.
Keep working and best of luck to ya.
