Josh Fields expressed his desire on Friday to compete for the Astros ninth-inning gig, but understands why a pair of veteran hurlers were brought in as well. Jesse Crain and Chad Qualls were acquired via free agency this offseason, with Crain the leading candidate for saves in the Astros bullpen provided he's healthy to begin the season. Fields, who finished the season in that capacity, posted a 4.97 ERA, 1.29 WHIP and 40/18 K/BB ratio over 38 innings of work in his rookie campaign.
