Surpassing CC Sabathia’s legendary mark, the 24-year-old left-hander posted a 1.57 ERA through 10 starts to silence doubters.

It's hard to explain just how good Kyle Harrison has been for the Milwaukee Brewers, but breaking this franchise record helps prove it.

Harrison just surpassed CC Sabathia for the lowest ERA from a starting pitcher in their first 10 games with the Brewers.

After another stellar start, Harrison's ERA has fallen to 1.57, which just so happens to top the 1.59 ERA mark that Sabathia set 18 years ago.

Harrison, 24, allowed just four hits in six shutout innings against the St. Louis Cardinals. He only struck out two batters, nine fewer than he did against the Chicago Cubs, but he's now made three straight starts without allowing a run and more impressively picked up his sixth win of the year.

Kyle Harrison's Dominant Start

Harrison now sports a 6-1 record and 1.03 WHIP in his first 10 starts with the team. Keep in mind, he only made 11 starts last year but went 7-7 with a 4.56 ERA in 2024.

Brewers pitching coach Chris Hook and Co. have struck gold once again as Harrison has allowed just 11 hits in his last three scoreless starts. Not only that, but he's struck out 20 batters and walked just one in that span. He's picked up a win in three straight games and has allowed only three runs in the month of May.

Sure, Sabathia was throwing complete games and has a larger sample size in that regard through 10 games. Still, this is an incredible accomplishment for Harrison, a player that Brewers fans questioned about when he came over in the Boston Red Sox trade.

It's safe to say that Harrison has proved the doubters wrong, and once again proved that pitchers go to Milwaukee when their career needs saving.

Harrison's Advanced Stats

Brewers beat reporter Adam McCalvy of MLB.com broke down some of the advanced numbers for the lefty.

Harrison’s ERA ranks third among Major Leaguers who have pitched at least 50 innings. His 4.7% barrel rate, per Statcast, ranks seventh. Harrison's 10.63 strikeouts per nine innings and 22.8 strikeout-to-walk percentage are in the top 10. His 29.6% strikeout rate is seventh. His .206 opponents’ average and 1.03 WHIP are in the top 20.

In a world where Quinn Priester is still recovering, Brandon Woodruff has been dealing with issues, and now Logan Henderson went back on the Injured List, Harrison has been everything this team has needed, and more.

Should Milwaukee keep up at this pace, there's no doubt he'll be the team's game two starter in any playoff series, right behind Jacob Misiorowski.
