His pro career is off to a fine start for the High-A Frederick Keys.

Lefty Joseph Dzierwa is 3-1 with a 2.33 ERA for Frederick. Over 27 innings he’s allowed just 15 hits with seven walks to 29 strikeouts. Showing a low-to-mid 90s heater and plus changeup, he has an 0.81 WHIP and opponents are hitting just .160 with a .497 OPS off Dzierwa.

O’s fans likely first saw him when he had a dominant outing in the March 20 Spring Breakout game versus Boston. He threw three scoreless and fanned eight Red Sox prospects that night.

Dzierwa is the highest-drafted pitcher by the Mike Elias front office, taken in Round 2 last year, No. 58 overall.

He is rated as the O’s No. 12 prospect via MLBPipeline.com and No. 17 by Baseball America.

We had a wonderful conversation taped on Friday when he and the Keys were in Brooklyn to play the Cyclones.

In this podcast Dzierwa told us about the tall lefty big league pitcher that has already given him some pointers. He explained how this Ohio kid went to college at Michigan State and how he has worked with the O’s pitching coaches thus far. We went over that, his repertoire and more.

He is quickly making a name for himself on the O’s watch.

Take some time to get to know lefty pitching prospect Joseph Dzierwa.

Yesterday in New York: Last year at this time, right-hander Trey Gibson was pitching for the High-A Aberdeen IronBirds. Right now Dzierwa is pitching in High-A ball. Could he move as fast as Gibson did and pitch at three levels this year? Well, he’s got a shot and is off to a great start this year. Enjoy today’s podcast.

Here is last night’s story on Gibson pitching well in his MLB debut, yet the O’s losing again in the Bronx. Game four of the series is tonight at Yankee Stadium.
