Other mistake: When Dixie's on the phone with the suicide attempt, Dixie tells her the date of her own birthday, hoping to get the caller's birthday in return. Then when the caller tells Dixie that the month of her birth is February, while Brackett's listening, they don't contact Early who's with the senior data analyst with that crucial information to help narrow down her identity faster, which was the whole point of Dixie trying to get that information from her.
Other mistake: During the fire at the horse ranch, when Engine 40 rolls up we can see that the engine company's number is covered atop the cab, and the large, red rectangular vinyl material that's adhered to the back of the engine with nothing on it. Presumably covering the real engine company's number.
How Green Was My Thumb? - S3-E17
Other mistake: When Station 51 is dispatched to the fire at the winery, just as Squad 51 rolls up, in this semi-closeup we can see that it's Roy driving and exiting the squad, and also that it's actually Randolph Mantooth's double exiting the squad and getting the drug box from the side compartment. Also fun to note the difficulty the double had just opening the squad's door.
Continuity mistake: While the judge and young lawyer are doing CPR to help, Roy's tearing off strips of tape and placing them on his pants (for IV as usual), then after he asks Johnny, "Were you able to get in touch with Rampart?," in the next shot all those strips of tape have vanished from his pant leg, only to reappear when Roy defibs the patient.
Heavyweight - S3-E5
Other mistake: When Chet is preparing the lasagna, then tells Johnny that he's preparing 'rutabaga delight' especially for him, the green container of parmesan cheese has tape covering the brand name, though it looks like it's the Kraft brand.
Heavyweight - S3-E5
Continuity mistake: At the start, after Station 51 is dispatched to the apartment fire, when a musician asks Captain Stanley for help removing instruments from the burning building, the next shot showing Truck 98 rolling up is footage from 2x13, "Drivers", during the fire at the Atlas Hotel. We can even see the smoke through the Atlas Hotel's windows, and Squad 51 parked across the street. More footage from the Atlas Hotel fire is shown when Engine 16 rolls up. Additional footage from other episodes are shown as well, when we see helmets and rigs bearing company numbers that were not called to this fire.
How Green Was My Thumb? - S3-E17
Continuity mistake: Before they bring in the young girl who fell (with a dog bite), Dixie tells Brackett that she'll set up for her in treatment 1, and after Squad 95 brings her in, when Brackett and the paramedic (Donald Mantooth) leave the room we see that she is indeed in treatment 1, which is beside receiving. However, when Brackett takes the parents to see her, they go through the door that's between the double doors and treatment 2, which are on the opposite side of the hallway from treatment 1. Then in the next shot they're back in treatment 1.
How Green Was My Thumb? - S3-E17
Revealing mistake: When Roy brings in the man with the laryngeal obstruction (partial dental plate), Morton and Early meet them at receiving, then as they rush the stretcher into treatment 1, it's amusing to note that the treatment room across the hall (treatment 2) has room number 412 on it, and even better, treatment 1 itself has number 411 on its door. Obviously the set was prepped for the following shots, when Johnny follows the nurse onto the 4th floor.
Inventions - S3-E22
Other mistake: When Station 51 responds to the incident of the man who fell through the ceiling at his mother's house, the footage of the squad and engine pulling up to the curb of the house is from episode 3x15, "Messin Around", when they rescue Old Bill after he's collapsed in his house.
Revealing mistake: When Cindy and her mother come to see the station, Cindy goes to the closet with the gear, and as she opens the door Cindy starts laughing before Johnny even gets hit by the phantom, and then she glances toward the camera grinning because of the prank.
Other mistake: After Johnny gets hit by the phantom in the apparatus bay, Station 51 is dispatched to an unknown type rescue at 617-1/2 Kimball Rd, and before the dispatcher even gives the address, Mike has already located the area on the map with his finger.
Visible crew/equipment: While the guys are at the table eating Marco's stew, when Johnny remembers that he spent $8.42, numerous set lights are reflected on the coffee pot's chrome surface.
Revealing mistake: When the guys are in the backyard with the woman who fell through the ground into an old abandoned well, in the overhead shot we can see the cuts that created the cutout hole on the flat surface around her, and that it's not really dirt or sand that she's slipping through.
Continuity mistake: When the guys are eating dinner talking about marriage, John's glass of milk is half full in the shot from behind him, but when Barbara calls the station and Captain Stanley answers the telephone, John's glass is nearly full in the shot facing him.
Character mistake: When Johnny and Roy respond to the 'possible injury at the horse ranch', after the guy who was knocked unconscious gets back on the horse, Johnny tells Roy, "Why don't we stick around for another few minutes, unless we get another call." They did not contact the dispatcher that the squad's available, so they would not even be dispatched to another call, since they're already on that run.
The Promise - S3-E11
Revealing mistake: When Richard jumps out of the 6th floor window, in the interior shot we see that he lands right at the base of the window's frame, as his body bounces back from the impact, but when Brackett looks out the window Richard is lying on the ledge, which is much farther down than the window's bottom frame.
Continuity mistake: After the paint factory fire, when Roy and John are with the lawyer in Captain Stanley's office, Roy's chair is either directly in front of the desk or off to the side, depending On Camera angles. Their body positions change between shots as well.
Other mistake: During the fire at the paint factory, just after the barrels at the back of the pickup up truck explode, in the next shot we see Marco and Chet manning a hose. In this closeup, another fireman runs up to them and he's wearing a helmet with 51 on it, but it's obvious he's not one of 51's guys, plus Roy and John are with the burn victim and Mike's at the engine. The fact that it's a closeup and we can see perfectly well that he's not actually from 51 makes this too odd.
Other mistake: After Mr. Winthrop is brought to the ER, there is a closeup of his EKG monitor as it's picking up multiple PVCs, but when Brackett asks him about the tension in his life, the monitor seen behind him is showing a flat line. This happens once again after Roy and John leave the treatment room, just before they move him to CCU.
Other mistake: After Roy and Johnny get back to the station, when Johnny takes the container of milk out of the fridge, we can see the black tape around it covering the brand name. There's another container in the fridge with red tape covering its brand name as well.
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.
