MILWAUKEE -- The A's road woes continued in Milwaukee on Wednesday night, a less-than-inspiring lineup that was missing three of the club's best hitters mustering only three hits in a 4-0 loss to the Brewers, their fifth straight defeat on what's been a mostly disheartening trip.
Sonny Gray's return in Houston on Sunday offered hope, only for the A's to learn Wednesday afternoon that lefty Rich Hill, he of a 2.25 ERA, is likely disabled-list bound with a groin strain.
Piecing together a rotation has been no easy task for this club, magnifying the ongoing struggles of several of its members -- Jesse Hahn included.
Hahn, who was tagged for seven runs while recording just two outs in Houston on Friday night, again didn't stick around as long as the A's would've liked, lasting only 3 2/3 innings with four runs and eight hits allowed against Milwaukee.
The right-hander, reliable for the A's last season before suffering a season-ending arm injury, gave them only 4 1/3 innings in two starts on this road trip, having yielded a combined 11 runs and 14 hits. Three times on Wednesday he allowed a lead-off single -- all of which scored.
"I'm just putting myself in jams," Hahn said. "I have to do a better job of being more efficient, getting ahead of hitters, and limiting the damage in some of these innings. These last two starts, I've let these innings blow up on me, and I can't do that.
"As a whole, as a team, we're not playing the baseball we want to be playing in the last week or so. We're capable of a lot better ball. Obviously, we'd like to have a guy like Rich in our rotation because he's been getting it done for us all year. The rest of us have to step up and do our jobs."

Hahn's ERA sits at 6.49. Kendall Graveman sports a 5.49 mark, rookie Sean Manaea is pitching to a 6.20 ERA, and even Gray's is at 5.77 for the last-place A's.
The offense, at least of late, hasn't been able to produce enough to offset these shortcomings, though it's been a tough order without right fielder Josh Reddick, on the disabled list with a fractured thumb. Khris Davis (elbow) and Danny Valencia (flu) were also absent in the Milwaukee series, though both are expected back Friday in Cincinnati.
"When you don't have your 3-4-5 hitters, sometimes it's a little tough to get anything going up and down the lineup when you're relying on those guys to do some damage," A's manager Bob Melvin said.
"Reddick doesn't get spoken about enough, him being out," Vogt said, "but I think we're all guilty of that at times, trying to do more than we're capable of. I think we have the people in here to do it, just a matter of everybody clicking on all cylinders at the same time.
"We don't quit, we still feel good about this team in here, it's just been a frustrating five days so far."
