From 2018 to 2024, there were three things certain in Houston: Death, taxes, and Ryan Pressly coming in late in an Astros game to preserve a lead. He is fourth all-time in saves with 111 among Astros relievers behind Billy Wagner, Dave Smith, and Brad Lidge. In one stretch from August 15, 2018, until the end of that season, Pressly had 21 straight appearances without allowing a run.
In his heyday with Houston from 2018 to 2022, his ERA was sub-3.00 for four out of five years, with peripherals to match. However, in 2022-23 there was a noticeable decline: ERAs in the mid 3s, decline in velocity, K/9 down from about 12.
