Chad Qualls RP HOU 2 Days

Qualls (hip) earned his 18th save of the season Monday with a scoreless ninth inning against Cleveland.

Making his first relief appearance for the Astros since September 6 after a nagging hip injury, Qualls permitted a single and struck out a batter in the scoreless frame. The veteran reliever figures to close out the season as Houston's closer, or at least share the role with Josh Fields, who filled in during Qualls' recent absence.

Qualls (hip) is available to pitch Monday if needed, Howard Chen of CSN Houston reports.

Because of the injury, Qualls has not appeared in a game since September 6. Josh Fields has been filling in as the team's closer in Qualls' absence, leaving the veteran's role as an uncertainty for the final two weeks of the season.

Qualls was unavailable again Wednesday due to a nagging hip injury, MLB.com reports. "I don't know if it's a tight hip that's putting pressure on a nerve back there," Qualls said. "I get a warm feeling like in a 6-inch [region] down the side of my leg. When I sit down or lay down, it really doesn't hurt, and if I walk around, it gets irritated or something."

With Qualls' discomfort failing to subside over the course of five days, the training staff went ahead and prescribed rest for the 36-year-old right-hander. Josh Fields has collected a pair of saves since Qualls' last appearance and is the clear favorite for opportunities until Qualls returns, but lefty Tony Sipp nailed down a save Wednesday and could see chances depending on the matchups.

Qualls took the loss in relief Wednesday, allowing three runs on four hits over two-thirds of an inning against the Athletics.

Qualls will remain with the Astros for the rest of the season, MLB.com reports.

Qualls was claimed off waivers by the Tigers earlier in the week, but Wednesday's deadline for the teams to complete a trade passed without Qualls switching teams, and he can no longer be traded to any other squad. Qualls will continue working as the Astros' closer.

Qualls earned his 15th save of the season Tuesday with a scoreless frame against the A's.

Qualls was claimed off revocable waivers by the Tigers on Tuesday, but the veteran reliever did not let the news affect him in preserving a 4-2 win over Oakland. The Astros and Tigers have until Wednesday to work out a trade, but there's a strong likelihood Houston will pull Qualls off waivers rather than trade him.

Qualls has been claimed off of revocable waivers by the Tigers, MLive's James Schmehl reports.

With this development, Qualls could soon join the Tigers' bullpen. However, there is no guarantee that a deal will materialize, as the Astros do have the option of hanging on to their veteran closer. The two teams have until Wednesday to come to an agreement. Qualls has turned in a solid campaign in Houston to this point, converting 14-of-17 save chances while posting a 3.07 ERA and 38:5 K:BB ratio across 44 innings.

Qualls (back) pitched a scoreless ninth inning in a non-save situation Friday.

Qualls was unavailable for the final two games of the Yankees series due to back discomfort, but he got back on the hill Friday and retired the side on 14 pitches. After struggling in July (7.71 ERA), Qualls has now given up just one earned run in seven August appearances, thus further cementing himself into the closer role for Houston.

Qualls (back) said he's "probably unavailable" Thursday against the Rays, MLB.com reports.

Qualls did not pitch Wednesday due to discomfort in his back stemming from Friday's game. While it doesn't appear to be anything serious, Qualls could miss a few games in the short-term.

Qualls was not used in a save situation Wednesday due to minor back discomfort, Evan Drellich of the Houston Chronicle reports.

The sore back cost Qualls a potential save Wednesday night, but it appears to be just a short-term issue, as manager Bo Porter said Qualls would likely be available Thursday if needed. However, consider Qualls day-to-day until he is summoned from the bullpen next.
