Welcome to Santa Rosa County - S6-E10
Other mistake: When Roy and Johnny begin their ascent, the injured rock climbers are shown in a closeup, which then zooms out so we can see the entire area to the left, and the only rope up there is the boys' red rope. When Johnny reaches the boys, he's pulling himself up with the help of a blue rope, which has already been anchored in place near the injured boys. So who put it up there and anchored it? Not the injured boys. Not Johnny. Not Roy, who is still down below.
Answer: I was rewatching a few first season episodes of Charlie's Angels (1976), and in S1xE6 "The Killing Kind," I recognized the same actor. So, to finally fully answer your question, the two baseball players in School Days are played by Rod Perry and Sean Fallon Walsh.
