Scuffling right-hander Josh Fields will not be used in late-inning pressure situations for the Astros for the time being, Bo Porter announced on Friday.

Fields has been miserable lately. He has given up nine earned runs on eight hits in his last 1 1/3 innings as his ERA has skyrockted to 9.58. He has struggled in particular against left-handed batters.

The job of holding opponents down late in close games will fall on Chad Qualls and Anthony Bass until further notice.
