With Ryan Feltner still sidelined with back spasms, the Rockies needed a new starting pitcher to kick off their series in Arizona last week. They turned to tricky left-handed pitcher Carson Palmquist (no. 9 PuRP) to make his big league debut. Palmquist—a 2022 third-round pick out of Miami—had been pitching very well in the hitter friendly PCL this season with the Triple-A Albuquerque Isotopes. In seven starts and 35 1⁄3 innings he posted a 3.82 ERA with 45 strikeouts.
Palmquist’s debut did not go as planned. In four innings, he gave up five earned runs on six hits while also walking a batter and failing to notch his first big league strikeout.
