Again, with my limited information it seems we have had a lot of injuries and are relying on some very young players. No college baseball team at our level is full of depth or experienced depth.
I would be much more concerned if this team were getting beaten 12-0 or 14-2 or 9-1 but it seems our guys are right there in most every game. By right there, I mean a hit or a pitch or a defensive play away from securing victory. To me, that shows that this team with these coaches are very close.
Yes, I have seen where many games have been lost in the late innings and they're always going to be those who question why did he OR why did he not make that pitching change? - Unless a coach has Mariano Rivera or Craig Kimbrel down there in the pen then my experience tells me that this decision is the hardest decision to make in baseball - (Believe I made as many bad ones as good ones)

Baseball is a really tough game to coach in regards to holding a lead - You can't run out the clock by running the QB up the middle OR milk time as the shot clock counts down - You must continue to pitch, thus giving every opponent full advantage of making a comeback - and you can hit the ball as hard as possible and it goes right to a fielder and they can barely get the bat on the ball and it falls in down the right-field line for a double - that, or similar, happens all the time in baseball and rarely in other sports ---
My take is to give these guys some time to build some depth, nurture our player's experience, and hit the recruiting trail ---
