• 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.
