Earlier this week I posted a video of Jameson Taillon pitching against the New York Yankees’ farm system in a Spring Training game at Pirate City. After Taillon pitched three innings, Zack Von Rosenberg came on to pitch the next four innings. Von Rosenberg mostly sat in the 88-90 MPH range with his fastball, and got hit hard at times, as he mostly worked on fastball command. He did display a nice curveball, getting a few strikeouts and swinging strikes with the pitch.
In the first, Von Rosenberg sat at 88 MPH, with a 78 MPH curve. He allowed a double and a single to start off, then got a double play and another ground out to get out of the inning. In the second inning he was sitting around 89 MPH, and had a nice strikeout on a 74 MPH curveball. He topped out at 90 MPH in the third, but dropped to 85 MPH towards the end of the inning. He allowed a bases loaded triple during the frame. In the fourth he was again at 85 MPH, but again topped out at 90 MPH. He was affected by two errors from his defense.
Here is the video of Von Rosenberg pitching during the outing.
Tim started Pirates Prospects in 2009 from his home in Virginia, which was 40 minutes from where Pedro Alvarez made his pro debut in Lynchburg. That year, the Lynchburg Hillcats won the Carolina League championship, and Pirates Prospects was born from Tim's reporting along the way. The site has grown over the years to include many more writers, and Tim has gone on to become a credentialed MLB reporter, producing Pirates Prospects each year, and will publish his 11th Prospect Guide this offseason. He has also served as the Pittsburgh Pirates correspondent for Baseball America since 2019. Behind the scenes, Tim is an avid music lover, and most of the money he gets paid to run this site goes to vinyl records.
That is a very nice curve. Not too loopy and had guys way out in front of it.
Any chance that some of his low 80’s pitches were rudimentary changeups?
Is it just me, or does it look like he throws harder out of the stretch?
