Other mistake: When Brackett asks Early to see the patient (Jaime Farr) who claims he can't move his arm because of a curse, Early walks into treatment 5, but in the shot from inside the room we can see that they're in treatment 2.
Other mistake: When Roy and Johnny are with the woman whose hand is caught in the mixer, we can see tape on the side of the stand mixer (Sunbeam) as well on the food containers, covering all their brand names.
Other mistake: Jamie Farr appears in 2x19 "Boot" as Alan Austen, the guy who claims that he can't move his arm because of a curse, but he's mistakenly listed in the credits at the end of this episode.
School Days - S2-E14
Continuity mistake: Before the housekeeper leaves the library to open the door for 51's guys, we see Dr. Temple pinned under the bookcase and two red armchairs in front of the fireplace, but when she returns to the room with everyone following her one of those armchairs has vanished.
Other mistake: When Johnny and Roy are with the baby who's sleeping in the back seat of the locked car John says, "The roof is hot, I think the heat might have built up inside," and the bystander says, "Lord knows how long he's been lying in there broiling in the sun," but what's funny is that they're all wearing winter coats and jackets.
Continuity mistake: After 51's guys rescue the man from under the fallen engine, when the ambulance leaves we can see only the name Mayfair is printed on its side, but en route to Rampart and when Roy has the ambulance stop and then go, there's a red cross printed on the surface above Mayfair.
Continuity mistake: During the structure fire, after the parents realize their son ran back into the burning house to get the dog, when the father tries to go after the boy we can see the man's wearing a striped T-shirt under his robe, but when Roy rescues both the boy and the dog, the father is now wearing a white T-shirt under the robe.
Other mistake: After rescuing the boy and his dog from the structure fire, when both of 51's rigs are backing up the driveway, the office door opens and we can see through the glass door that someone is standing there, even though they're all on the rigs. Next shot, that phantom individual has vanished.
Visible crew/equipment: During the structure fire, after Roy finds the boy and his dog under the bed, when Roy heads down the stairs and then rushes back up, as he gets to the top of the stairs when the camera pans to the left we can see the barndoor set lighting, at the top left side of the screen.
Audio problem: When Squad 51 is dispatched to the hotel fire, Roy's holding the bullhorn in one hand to instruct everyone, and the HT in his other hand. After Johnny catches the baby, just before Truck 8 rolls in, when Roy says over the HT, "All right, set up the Truck...," he moves his hand with the HT away from his face and directs Truck 8, yet his voice is still booming as if speaking into it.
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.
Visible crew/equipment: While en route to the structure fire, Mike is driving Engine 51, and seated backwards in the jumpseat behind Mike is Marco, who's wearing a helmet and his turnout, but in the shot from the POV behind Mike, we see the reflection in the rear-view mirror of the grey haired crew member, who is seated facing forward behind Mike.
Audio problem: When Roy and Johnny are tending to the actor with possible MI, Brackett asks for an EKG strip, and after Johnny hooks the scope up to the Biophone, we hear him say, "Lead 2," but his mouth is closed and doesn't move.
Other mistake: While the guys are in the kitchen, deciding whether or not to keep the dog and then what to name him, when Chet is drinking the milk, we can see the red tape covering one side of the container to hide the brand name and logo.
Other mistake: When Squad 51 is dispatched to the movie studio, while en route in the interior shot, in the rear-view mirror we see the reflection of the driver's helmet, and it has an 18 on it, instead of 51.
Continuity mistake: When Mrs. Epps begs Dr. Morton to tell her the truth about her son's condition, the stethoscope is hanging around Morton's neck with the headset on his left side and the chestpiece on his right side, but then it flips to the opposite way, and then back again, between shots.
Continuity mistake: When Roy and Johnny are at the construction site with the guy who wants to jump, before Roy walks over to him we see the pompier belt around Johnny's waist has the carabiner hook to his left and the double tongue buckles to his right. Then when Captain Stanley tells Johnny to try and get to the guy from the other side, Johnny's belt is now around his waist the opposite way. In the following shots his life belt flips around a couple more times. Note that their pompier belts have at one side double leather straps which are the two tongue buckles, and the other side has a single strap of leather for the attached carabiner hook.
School Days - S2-E14
Visible crew/equipment: When Squad 51 gets pulled over to help the guy with a snake on his stomach, just as Johnny reaches over to take the broom from Billy, the outline of the lav mic transmitter is visible on the back of Johnny's shirt.
School Days - S2-E14
Character mistake: When Dixie tells Gail to set up in treatment 1, Brackett tells them they can't use treatment 1 because they have a skull fracture coming in, then Brackett and Early head down the hallway to treatment 1, and that skull fracture, Skyle Tyler, has already been lying there being examined by Morton.
Other mistake: During the structure fire at the Atlas Hotel, when Roy and John are with the unconscious man being given proper CPR by civilians, it is too painfully apparent that the man giving rescue breaths is just leaning over the man's face, nowhere near the victim's mouth, particularly after Marco and Chet drop off the 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.
