Pirates Minor League Recap: Burrows Strikes Out Eleven, Griffin Stays Hot

In this story:
Yesterday, MLB Pipeline unveiled the most recent update to their Top 100 Prospects list. Five Pirates made the list, with one particular standout situated at the top of the list of pitchers.
After a dominant start to the season, Bubba Chandler continues to cement himself as one of baseball’s most electric pitching prospects, moving up to No. 2 on MLB Pipeline’s Top 100 Prospects list — the highest ranking by a Pirates prospect since Paul Skenes held the same spot last May. With Detroit Tigers starting pitcher Jackson Jobe's graduation to MLB, Chandler becomes the highest ranked pitching prospect on Pipeline's list.
The 22-year-old right-hander has been utterly dominant at Triple-A Indianapolis, posting a 0.93 WHIP with 41 strikeouts in 28 innings, backed by a 98.3 mph fastball with elite movement and two promising secondaries. His rapid ascent gives Pittsburgh yet another potential frontline starter in the making.
While Chandler headlines the system’s success, other prospects are making moves as well. Shortstop Konnor Griffin (No. 37, up from 44) has impressed in Low-A with a .283/.341/.504 slash line, 6 HR, 17 RBI, and 13 steals, showcasing his five-tool potential. Meanwhile, lefty Hunter Barco (No. 94, up from 100) has been nearly untouchable between Double-A and Triple-A, posting a 0.30 ERA and 0.77 WHIP with 39 strikeouts in 30 innings.
However, not all trends are positive. Former first round pick Termarr Johnson (No. 87, down from 74) apparently hasn't done enough this season to move up the list, while Thomas Harrington (No. 84, down from 71) has struggled in Triple-A with a 5.40 ERA in five starts.
Still, with Chandler leading the charge and Griffin and Barco surging, the Pirates’ farm system remains loaded with high-ceiling talent.
