“Solo home runs/homers don’t/won’t beat/hurt/harm/kill you” is a baseball saying cited in print since at least 1986. A solo home run accounts for only one run, leaves no runners on base, and usually occurs only about once or twice during a game. A pitcher shouldn’t stop throwing hard just because of one solo home run.
 
The baseball adage doesn’t always apply in every situation and solo home runs can win low-scoring or extra-innings games.

Matt Garza gave up all three jacks on Saturday. They were all solo shots, and an old baseball adage says solo homers don’t beat you. Give up enough of them, though, and they will in fact do just that. And the cozy confines of Citizens Bank Park magnify that challenge.

When Lou Pinella was the Mariners manager he used to say, in his inimitable way, solo home runs don’t beat ya.
 
Tuesday night the Yakima Bears proved Pinella wrong.
 
Of course, they hit four of them.
 
All during the first four innings.

I would agree
Bert often says (and I actually agree with this one) that solo homers don’t kill you. They hurt when there are guys on base, and Joe is pretty good at that.
 
A run driven in with a single is every bit as good as a run driven in by a solo HR. Or, as Kubel showed, a 3 RBI double is pretty fun too.

“I think all the runs were on solo home runs. The old adage is that solo home runs don’t beat you. But we didn’t hit. We didn’t give him an opportunity. But I saw something in Mike today. I saw some growth in him.”
