Cook's Tour - S1-E4
Visible crew/equipment: At Rampart, after the baby's birth, when Gage and DeSoto walk over to Dixie, the first actor's T-mark is visible on the floor just before Gage stands there, and a second actor's mark is visible under the stool, where DeSoto will be seated in a moment.
Visible crew/equipment: Station 51 responds to a building collapse with the trapped boy, and when they enter the building with Tommy's friend, the actor's white T-mark is visible on the floor.
Continuity mistake: Just as Gage and DeSoto walk into Rampart's staff lounge, while discussing practical jokes, DeSoto is holding the handy-talkie in his right hand, but in the next shot the handy-talkie has vanished.
Visible crew/equipment: When Dr. Bracket leaves the treatment room with Jenny, who's being wheeled in the wheelchair, he tells her to see her family doctor just as Dixie exits the door, and the shadow of the moving boom mic is visible on the wall, at the top to the left.

The Wedsworth-Townsend Act - S1-E1

Visible crew/equipment: At Rampart, when Dixie walks over to Dr. Brackett, who stands behind the station, the tape mark is visible on the floor, just before she steps precisely on it.
Continuity mistake: When Gage plays the new game of poker with Kelly, the entire left side of the table is visible as the two begin. Next shot, DeSoto is suddenly sitting at that end, with an additional cup and saucer, opposite Kelly and Gage.
Continuity mistake: When John first explains how to rescue the little girl in the hole, he wraps his left hand around his right wrist, but in the next shot it's his right hand that's around his left wrist.
The Wedsworth-Townsend Act - S1-E1
Visible crew/equipment: When 127's snorkel is raised to rescue the man who was electrocuted atop a utility pole, as he's being loaded, in the first closeup within the snorkel, we can notice two things. We can see someone wearing denim at the left of the screen between 127's guy and Johnny, and we also see the ground past Johnny's head. Then as the snorkel is still being lowered, in the shot from the same POV, once again at the left we see that crew member wearing denim, who is outside the snorkel basket, and also see the ground, but the ground has not changed. This reveals that these two closeups were shot at ground level.
Other mistake: When the tones drop and the lights come on, waking up 51's guys in the middle of the night for the industrial fire, there are two closeups of the guys putting their feet into the boots and pulling up their turnout trousers. The problem is that the closeups are not Station 51's guys - note the beds, linens, walls, floor are all different. The two closeup shots are from the first episode "The Wedsworth-Townsend Act", and the guys are from Station 10.
Visible crew/equipment: When Johnny and Roy are back at the command post and hand over the looter (Tony Dow) to the deputy, the four actors' marks are visible on the ground where they stand.
Visible crew/equipment: At Rampart, when Gage and DeSoto walk into the staff lounge, where Dixie and Dr. Brackett are seated at the table, there is an actor's T-mark on the floor behind Dixie, where DeSoto stands.
Continuity mistake: When Frankie lands the Cessna, the red seatbelt is in place behind him. When Gage and DeSoto reach the plane that seatbelt has been pulled across the side wall, over the door, with its end pushed between the windshield and ceiling. Done deliberately so Gage can enter that door unhindered.
Deliberate mistake: At the station, Gage is washing dishes and talking about his idea for a new poker game. In this shot the camera is positioned behind the kitchen's top/lower cabinets and sink, facing Gage. The fact that we can see the back side of the cabinetry (paper towel dispenser which hangs over sink is gone) ruins the illusion of this POV from the wall that should be there.
Other mistake: When Station 51 is dispatched in the middle of the night to the industrial fire, the dispatcher says "Time out 1:07," but later at Rampart after Brackett tells Johnny to stay the rest of the night because of the exposure to the radiation, we hear the voice on the PA announce, "Visiting hours are over" even though it's supposed to be at least 3:00 AM.
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.
