On Monday night, St. Louis Cardinals Gold Glove shortstop Masyn Winn unleashed a throw in the top of the ninth inning against the San Francisco Giants that was thrown 99.8 MPH. It was the second-fastest infield assist in the Statcast Era (since 2015). Winn's bullet to first baseman Alec Burleson clinched a 2-1 victory for the Cardinals. For one former player, the throw was unnecessarily fast.

Winn's throw helped Riley O'Brien record his MLB-best 37th save of the year. The game was nearing peril, as there were runners on second and third with two outs and a one-run lead in the balance.
Christian Koss, the batter at the time, has an average sprint speed of 28.9 feet per second. On this particular play, he reached 30.3 ft/sec. For Justin Turner, a noted Masyn Winn dissident, the throw was just too fast.
According to Turner, Winn only needed to throw the ball 88-90 miles per hour to get Koss out at first. This assumes that Masyn Winn can stop play, calculate how hard he needs to throw, and then execute that play. This is preferable, according to Turner, than seeing a seed thrown across the infield in a big moment in a game.
Turner went one step further, resorting to ChatGPT to defend his thesis after a Cardinals fan called him out on it.

I watched the uploaded clip frame-by-frame. This is a much tighter calculation than I expected.
The overlay confirms Winn’s throw was 99.8 mph and the runner was moving 30.3 ft/sec. The important thing is that we don’t need to redo the runner’s entire…
Rather than just appreciating the speed and accuracy with which Winn executed the play, Turner opted to lessen the uniqueness of the play and use an AI assistant to say that Masyn Winn didn't need to throw it that hard.
"So if the question is “what’s the lowest velocity where I’d still bet on the out?” I’d call it ~86 mph. If we’re looking for the mathematical break-even point where ball and foot arrive essentially simultaneously, I’d estimate ~84–85 mph," said ChatGPT.
The AI analysis continued, reading, "And that really puts the 99.8 into perspective: he probably had ~14–15 mph of velocity to spare despite the runner going 30.3 ft/sec."
Rather than use his own thoughts and opinion, Turner opted to belittle Masyn Winn's all-time throw by using an AI chatbot.
Justin Turner continues to embarrass himself by criticizing St. Louis Cardinals Gold Glover Masyn Winn.
In 2022, when Winn threw a ball 100.5 MPH across the infield at the 2022 MLB All-Star Futures Game. This play received some criticism from Justin Turner, a former major leaguer. On a podcast appearance in 2022, Turner couldn't care less if a player could throw the ball 100 MPH across the field if it wasn't accurate.
Unfortunately for Turner, Winn has the third-best fielding percentage (.982) among shortstops since 2024. Clearly, he can throw it both hard and accurately.
Justin Turner, unfortunately, wouldn't have been able to make the play. He averaged a meager 80.63 MPH on his throws from third base. According to his (ChatGPT's) analysis, Koss would have been safe by a step and a half.
Masyn Winn continues to live rent-free in Justin Turner's head, and the more highlight-reel plays Winn makes, the angrier Turner gets.
