Revealing mistake: After Station 51 reaches the burning house, when Engine 210 rolls up and lays out a supply line, as the camera zooms in to the back of Engine 210, we can see the large, red, rectangular material that is adhered to the engine with the number 210 printed on it.
Continuity mistake: When Roy and Johnny are with the boy who is trapped on the crane, Johnny buckles the life belt around the boy's waist, and in the following shots the belt's direction flips around to the opposite way repeatedly. Note its stitched leather and tongue buckles.
Visible crew/equipment: When Roy and Johnny are walking down the hallway at Rampart, Roy asks Dixie for some supplies, just before Johnny spots Sheila doing uncover work, the two white tape marks are visible on the floor just behind him.
Continuity mistake: At the stationhouse, when DeSoto and Gage are discussing the detective, in the shots facing Gage, DeSoto holds a cup of coffee in his hands, but in the shots facing DeSoto his cup is on the table.
Visible crew/equipment: After John and Roy rescue the elderly man from the burning house, while Roy gets the man's vitals in the closeups, the large 12-light par bank rig is visible behind Roy at the left of the screen.
Continuity mistake: When Johnny and Roy are with the elderly man in the burning house, the window is pushed up fully when Mike climbs the ladder in the exterior shot, but when Mike breaks the window with the axe, the window is halfway down in the interior shot.
Other mistake: When the tones drop and Station 51 is dispatched to the "structure fire", there's a closeup of all the guys running from the kitchen and the back heading to the squad and engine, and none of them are actually 51's guys.
Continuity mistake: When Gage sees Sheila in the hallway at Rampart while she's undercover, he stops her midway between treatment room three and four and they are standing face to face. In the wide shots of both of them and in Sheila's close-ups, she's standing right in front of the emergency fire hose glass cabinet, but in Gage's close-ups, he's standing directly in front of the door to treatment room four, farther up the hallway.
Continuity mistake: At the park, when the attendants load the mugger into the ambulance, and also when the ambulance backs up to Rampart's ER receiving, just as Squad 51 turns and starts backing up, the type of ambulance that parked is a station wagon, but in the next shot while Squad 51 is still backing up, that ambulance has suddenly become the truck type.
Continuity mistake: When Roy and Johnny are rescuing the elderly man from the burning house, in the interior shot Roy exits the window by placing his left leg out the window onto the ladder, but when it cuts to the exterior shot Roy has his right leg out the window on the ladder.
Audio problem: When Johnny and Roy send down the boy who was trapped on the crane, once he's carried by Chet and the others, we hear Captain Stanley say, "Alright, let's get him into the Stokes, and get him outta here as fast as we can," but his mouth is not saying those words (though Chet's helmet blocks Cap's mouth for part, it applies to the rest). Additionally, it doesn't make any sense that he would even say that, because they're loading him straight onto the ambulance stretcher, not a Stokes.
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.
