BALTIMORE -- Orioles right-hander Jason Hammel said on Tuesday afternoon that he didn't experience any overnight discomfort in his right knee after Monday's start, and the 29-year-old righty is on track to make his scheduled start on Saturday against the Nationals.

Hammel, whose most recent start was pushed back from Thursday to Monday due to right knee soreness -- an injury that had gotten progressively worse in his previous few outings -- turned in his worst start of the season against the Yankees on Monday night, allowing five earned runs and exiting without recording an out in the sixth. The right-hander said afterward that his knee didn't bother him on the hill, but he did tire down the stretch because he hadn't conditioned as he typically would between starts.

"I felt fatigue from just not being on my feet," said Hammel, who has been receiving daily treatment on his knee. "But other than that, no pain, no soreness or stiffness."

Hammel said he will try to work in more conditioning later this week, although he didn't anticipate being cleared to run any time soon.

"I'm doing some pool work, so it's less impact on the knee to make sure we are going to get over the hump and there's not any setbacks," Hammel said. "I'll probably do that for at least the next couple starts."

Hammel is 4-1 with a 2.68 ERA this season.

O's lean toward second injection for Reimold

BALTIMORE -- Orioles outfielder Nolan Reimold isn't showing signs of improvement from Friday's epidural injection in his sore neck, and manager Buck Showalter acknowledged on Tuesday that administering a second shot -- which would further delay Reimold's timetable -- is becoming increasingly likely.

"Every day, you are hoping he takes that step," Showalter said of Reimold, who was placed on the disabled list on May 1 with a herniated disc. "I'd be less than forthcoming if I didn't think that the possibility of a second injection isn't a probability."

Reimold, who was put on an anti-inflammatory steroid medication earlier in his recovery, was given the epidural in the hope of speeding up the recovery process. So far, that hasn't been the case, as he's still dealing with some tingling in his left thumb and discomfort in the left forearm/shoulder area, which is very weak.

While the team hasn't made an official decision on a second epidural, it's hard to imagine a scenario that would involve Reimold, who last played on April 30, returning from the DL before June.

"It's pretty slow," Reimold said of his recovery. "So, it's pretty frustrating just sitting around. And I don't know if there's some magic cure where I wake up and feel better or if it's going to be slow and gradual, where I feel better every day. ... I was hoping with the shot I would just wake up and it'd be gone. But that hasn't been the case."

"There's a progression you have to do where he just doesn't walk in here and feels great and heads to [Double-A] Bowie," Showalter said. "That's not going to happen. There's some in between here."

Tidbits

• Left-hander Zach Britton threw 47 pitches across four scoreless innings in his second extended spring start against the Boston Red Sox. Britton allowed two hits and struck out four, then finished up with 20 more pitches in the bullpen. He said his arm felt great, and the plan is for Britton to throw around 80 pitches on Monday. If all goes well there, Britton would head out on a rehab assignment with one of the O's Minor League affiliates.

Tuesday's game, which was played at the O's spring complex in Sarasota, Fla., featured Red Sox veterans Ryan Kalish and Jason Repko. It's not known how many rehab starts Britton would need to make, but Showalter has said previously that the organization is targeting an early-June return for Britton.

• Right-handed reliever Matt Lindstrom has been diagnosed with a partial tear of the ligament in his right middle finger, and he will remain in Baltimore for the next few days because there's nothing he can do for the pain at this point. Lindstrom, who was placed on the DL on Friday, said on Monday night that his MRI exam actually showed good results because it's not a full tear -- which would require a much longer recovery -- although it's too early in his recovery stage to start predicting timetables.

• Taylor Teagarden is back on a stabilization program for his back in extended spring camp, and Showalter said the catcher has been feeling much better. Third baseman Mark Reynolds and outfielder Endy Chavez also headed down to extended spring camp on Tuesday.

• The O's Triple-A affiliate, the Norfolk Tides, announced on its Twitter page that left-handed pitcher Dontrelle Willis has been removed from the restricted list and assigned to Class A Aberdeen's roster.
