Every Astros fan who pays attention knows that having Tony Sipp as the Astros LOOGY (left-handed one-out guy) is not ideal. In the past two years, he has struggled greatly. If his production does not drastically improve, I do not think he will last thirty days on the roster.
Sipp had a 4.95 ERA in 2016, and an even worse 5.79 ERA in 2017. That kind of STATS does not belong on a World Series Championship caliber roster.
The Astros have other pitchers cemented into the Astros roster who has proven to be able to get outs against lefties.
