Question I have pondering for a few years now?
 

I noticed it again yesterday in the Cubs-White Sox game and have seen it often the past few years. A runner from second scores on a routine single to left field. Are the runners that much faster or have the outfield arms become so bad?

thanks.

How many outs?

Two.

You’re supposed to try and score on that, with two outs no matter the era. Runner going on contact and hopefully getting a decent lead if they’re a smart baserunner.

If it was a 3 and 2 count with a man on first, runner should be near 3rd base by the time the ball crosses the plate.

Who’s playing Left Field might certainly come into play also.

Of course you are supposed to try and score but one listened to the 3rd base coach so you don't run yourself out an inning. However, I remember lots of 3rd base coaches holding the runner because most left fielders were being able to throw the runner out, now it isn't even close. This outfielder had a short left field (meaning it wasn't a long single but a short one) and he didn't have the arm to even come close.

I haven't noticed anything unusual in either strategy or skill level, other than maybe the shifts and outfield positioning have on occasion made it more difficult to get to the ball quickly. Agree that in general you should try and score if there are two outs and that the jump you get from that scenario makes it easier. Heck I watched Max Kepler score from first on a single the other day because he was running on a 3-2 pitch with two outs.
