Other mistake: When Roy and John are examining the boy who jumped from the ledge, they're standing at the back of Engine 85 while the boy's sitting on the tailboard, and we can see behind his head the vinyl material with the imprinted 85, covering the attached plate with the real company number.
Other mistake: Over the phone the bookie tells Sidney, "I'm having them pains again. I don't feel so good. Would you call some...," then collapses onto the floor. Then Station 51 is dispatched to "Possible heart attack," and the address is given, along with the apartment number 23. After 51 breaks into the bookie's apartment, soon one of the phones ring and Captain Stanley says, "Let me get this straight. Your name's Sidney, and you phoned in the heart attack, right? Now we're getting somewhere. How come you didn't have the address? What's your last name Sidney?" However, 51 was dispatched to the proper address and even the apartment number. Nobody else knew of the heart attack, and the victim did not phone it in.
Loose Ends - S6-E12
Other mistake: While Brackett is a patient at Rampart, he phones to inquire about Tina, and when he rips off his hospital ID bracelet we can see the wood grain bathroom door as he heads for Tina's room. When he's in Tina's room, the wood grain bathroom door in her room is identical to the door in Brackett's room, revealing the same room is used for both patients.
Other mistake: When the woman from the car accident is in the ER, Morton uses the laryngoscope to intubate her, and hooks her up to the respirator, but then she goes into V-fib, and when the defibrillation and epinephrin are unsuccessful and she flatlines, even if the respirator hose came loose she would still have the intubation tube in her mouth, but she doesn't.
Paper Work - S6-E11
Other mistake: After 51 rescues the boy who was stuck in the storm drain and is brought to the ER, Brackett uses the laryngoscope for endotracheal intubation, but the problem is we can see when Brackett cups his left hand, he merely places the distal end of the laryngoscope over the top of his hand, not actually down into the boy's mouth.
Paper Work - S6-E11
Other mistake: When the foreman and secretary are rescued at the warehouse fire, two shots after we see the foreman climbing down the ladder, there's a shot of the grey steel drums marked 'acetone' with two lying on their sides on a wood pallet, while the guys hose down the fire. What's funny is that in the next shot there's a disposable plastic cup that has suddenly appeared on that pallet. Obviously while shooting the different takes one of the actors or crew members left their cup on the pallet before they resumed filming.
Other mistake: When Station 51 is dispatched to the "freeway accident," as the engine and squad roll out of the apparatus bay, we can see the real 127's vehicle still parked in the bay, near the rear door.
Other mistake: When the self defense instructor tries to use Mrs. Pestone to demonstrate the flip, he puts his arm around her and covers her mouth, then it cuts to a shot of Squad 51 rushing down a street. This particular shot is from 5x8, "The Lighter-Than-Air Man," when Roy drives past the school kids and crossing guard.
Other mistake: During the singles club fire, after Johnny and Roy check the men's room upstairs, there's a shot of firemen in full turnout gear with hoses, and this footage is from the first season's pilot episode, "The Wedsworth-Townsend Act."
Other mistake: During the actual cliff rescue of the hang gliding accident victims, Roy and John are wearing hiking-type shoes with ridges on the soles, not their uniform shoes.
It's How You Play the Game - S4-E19
Other mistake: After Chet says that he doesn't like when people expect too much of him, Squad 51 is dispatched to "man bit by an animal," and when Roy gets into the squad the highly reflective chrome spotlight has been sprayed with a dulling spray, to temporarily dull the surface.
Other mistake: When Squad 51 is dispatched to an 'unknown type rescue', as the squad rolls out we can see the Crown engine from the show's first two seasons parked in the apparatus bay, instead of 51's current Ward LaFrance.
Other mistake: When Station 51 is dispatched to the landslide, the engine company get into their turnouts and roll out, but in the next exterior shot as the engine drives past the camera, not only are the guys not in their turnouts, it's too obvious that none are 51's guys, and the one in Chet's jumpseat even leans forward. Presumably they're 127's guys. Also the light bar on the squad and the rotating light on the truck are not on.
Other mistake: When Station 51 is on scene at the landslide, there's a dresser on the grass in front of the house, and when the explosion occurs due to the broken gas main, in the closeups as Johnny dives to the ground there's what looks like a can of gasoline (used for the stunt perhaps) atop that dresser that wasn't there before, and it's also not in the wide shots as Johnny dives down.
Other mistake: After Brackett tries unsuccessfully to get O'Brien on the line to ask about the fish tank, it cuts to an exterior shot of Station 51, and we hear the dispatcher say, "All units responding with Engine 3 cancel," but subtitles read, "Four units with Engine 3 cancelled." Subtitles from Universal Studios 2010 DVD.
Other mistake: When the man injured in the manhole is brought to treatment 6, Early tells Roy to patch him up for an EKG, but the subtitles read, "Patch one from the EKG," and then Early tells the x-ray technician to do a skull and chest series, but the subtitles read, "Skull and chest searches." Subtitles from Universal Studios 2010 DVD.
Other mistake: During the fire at Hammond Chemical, when Engine 7 rolls up and lays duals, we can see the vinyl material adhered to the top of the cab covering the engine company's real number.
Paper Work - S6-E11
Other mistake: When Marco is taking inventory of what's in the refrigerator, the containers on the door have their brand names covered.
Other mistake: After Station 51 is dispatched to the structure fire, just as Roy and Johnny start heading upstairs we see footage from 4x3, "Gossip," when Johnny brings the hose to the stairs at the chemical fire, but the line doesn't reach so he leaves the hose at the bottom step, and they continue up.
Camera Bug - S4-E10
Other mistake: While Roy and John are at 68's, Roy goes to the stove to see what Bob was cooking when he started having pain, and the closeup footage we see of the pot of bubbling chilli is the same as some of the footage of Chet's chilli in 4x1, "The Screenwriter," when 'Miss October' stops by the station.
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.
