Revealing mistake: After Station 51 is dispatched to "traffic accident with injuries," when they're on scene at the plant with the injured tanker driver, pay particular attention to the background behind Engine 51 while Roy is on the Biophone with Rampart. When Brackett says, "51, can you give me any more information," we can actually see Station 51 aka 127, directly behind Roy.
Visible crew/equipment: When Roy and Johnny are with the teenage girl who OD'd, Roy walks over to the bystanders, and when he speaks to the mother and daughter, the perpendicular actors' marks are visible on the ground where they stand.
Continuity mistake: When Roy and Johnny get to the airport and start talking to the boy flying the plane, the clock reads 11:55, but when Frankie puts the oxygen mask on his father it's 12:15, then when Roy reassures the boy about flying straight and level, it's 12:40, and so on, even though it's really supposed to be only a few minutes between these shots.
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 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.
Continuity mistake: When Squad 51 is dispatched to the attempted suicide, the dispatcher states that he's in apartment 2A, and when Roy and John arrive at the scene the police officer also says he's in apartment 2A, but when they get to the second floor they pass apt 2A and go to the apartment at the end of the hall.
Continuity mistake: When dispatch calls on a possible overdose, Gage puts on his turnout coat and gets into the squad, but as they drive away from the station house Gage is not wearing that jacket, and when they reach their destination he is once again.
Continuity mistake: When the firemen cover the tanker in foam, the paramedics and ambulance drivers extract the tanker driver and place the patient on the stretcher they all get covered in foam, including the stretcher. Next shot, the stretcher, the patient and the men are all clean.
Continuity mistake: When Frankie flies the Cessna, he places an oxygen mask on his father. The style of the mask changes from either a round, large type, to a smaller, square type.
Continuity mistake: At the airport, when Roy is being told about young Frankie flying the airplane because his father had a heart attack, we see that Roy's wearing his uniform shoes, but in the shot of Roy following the airport employee while they're running into the building, Roy (perhaps his double) is wearing tan work boots. The uniform shoes are back when Roy uses the grounded plane's radio mic.
Continuity mistake: At the scene of the traffic accident, after removing the injured driver from the overturned tanker, when Roy gets the Biophone from the squad and John runs over to the ambulance stretcher, notice the red rectangular material adhered to the front of Engine 51's cab. We know that Engine 51 does not have a license plate on the front of its cab, and during this scene Engine 51 is being played by the real Engine 127, whose license plate is at the front of its cab.
Continuity mistake: When Roy brings the injured tanker driver into the ER, the attendants wheel the stretcher down the hallway passing treatment 3, and after Roy asks Brackett and Early a pointed question about the trucker's condition, the doctors also walk down the hallway passing treatment 3, in the direction of the nurses' station. But then we see that Early and Brackett are with the patient in treatment 3, which is right beside the ER's receiving entrance.
Continuity mistake: When 127 hoses down the underside of the overturned trailer, we should be able to see the water spray while John and Roy try to get to the trapped driver in the cab, but we don't even though we hear the audio of the hosing.
Visible crew/equipment: When the truck driver who felt like his head exploded is in the treatment room with Early, Brackett and Dix, as the camera passes behind Brackett it casts a moving shadow along the two walls.
Visible crew/equipment: When Roy walks into the ER with the man who attempted suicide three ways, due to the low angle of the camera we can see part of the unfinished ceiling of the ER set, near the nurses' station.
Nurse's Wild - S1-E7
Visible crew/equipment: After rescuing the man trapped at the chemical plant, DeSoto and Gage walk into Rampart and when Gage walks up the hallway with Ellen, the actor's black tape mark is visible on the floor, where Gage stops to flirt with the nurse.
Nurse's Wild - S1-E7
Continuity mistake: When Gage rides in the ambulance with the cardiac and gunshot patients, the windows between him and the drivers are opaque glass. In the next exterior shot, as they drive down the street, those interior windows are transparent.
Nurse's Wild - S1-E7
Continuity mistake: While Early, Dixie, and Brackett are talking in the hallway about going to lunch, Ellen comes out of the treatment room (opposite receiving) next door to treatment 2 and calls to Dr. Early, but when Early and Ellen walk back into that room, they are now in treatment 3, which is directly opposite from treatment 2.
Nurse's Wild - S1-E7
Revealing mistake: When Gage and DeSoto are on scene with the unconscious woman and a dog, they break the front window of the house. In the interior shot as DeSoto climbs through the window, there is a white wall beside the window outside, which blocks the view of the "outside." That wall does not exist in the exterior shots. The same thing happens when Gage opens the front door.
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.
