Pittsburgh Pirates: Huge Ke'Bryan Hayes Series, Poor SP, More Takeaways From Split With Atlanta

New relievers impress

Thomas Hatch made his Pirate debut out of the bullpen in this series while Colin Selby made his MLB debut. After making his Pirate debut against the Brewers, Andre Jackson was once again called upon in this series to give an extended relief outing.

All three of the bullpen newbies would put together impressive series.

It started with Jackson. In Monday night's victory, Jackson pitched 2 perfect innings of relief while stirking out 4. He has pitched 5 perfect innings of relief since joining the Pirate bullpen, stirking out 7 batters.

Selby pitched 1.2 scoreless innings in his MLB debut on Wednesday. He allowed two hits, walked a batter, and struck out three. Selby's stuff is what was most impressive, as his great spin rates and movements had Brave hitters looking silly.

The most impressive outing of them all was Thomas Hatch. Hatch, who just joined the organization as a waiver claim on Sunday, took over after Falter lasted just 4 innings on Thursday. While getting some help from his defense, Hatch needed just 42 pitches to pitch 4 scoreless innings. He allowed just two hits, did not walk a batter, and struck out a pair.
