If I could only utilize one term to describe the Astros bullpen in 2020, it was fool’s gold. Although there were some promising performances — particularly late in the season into the postseason — the relief corps in Houston had some major flaws. For example, a 12.4 percent walk rate in the regular season, which tied the Mariners for the second-highest mark in baseball. Only the Mets at 12.6 percent had a higher “free pass” rate. That’s not good no matter how you’d try to analyze it.
To be fair, the unit did mainly consist of rookies for the majority of the season.
