Pirates are promoting RHP Thomas Harrington from Triple-A Indianapolis, according to Noah Hiles of the Pittsburgh Post-Gazette.
The Pirates decided last week to keep Cameron Mlodzinski over Harrington for the final spot in the rotation, but Mlodzinski allowed four runs on seven hits in 3 2/3 innings, and it appears the Pirates will now turn to Harrington, who will start on Tuesday against the Rays. The 23-year-old has yet to make a start in the minors this season, but he posted a 2.61 ERA, 0.96 WHIP, and 115/19 K/BB ratio in 117 1/2 innings last year split between Double-A and Triple-A. Harrington does not have the swing-and-miss upside of Paul Skenes or Jared Jones, but he has elite command and a deep five-pitch mix. His four-seam fastball is just around 92 mph, so he will need to rely on that command and sequencing to help him against MLB hitters, but he should be added in deeper formats and can be treated as a streamer right now in shallower leagues.
