Hall (knee) threw 35 pitches over two simulated innings Tuesday, Adam McCalvy of MLB.com reports.

Brewers manager Pat Murphy said April 28 that Hall (knee) has started playing catch and is "progressing," but the left-hander remains without a clear timeline for a return from the 15-day injured list, MLB.com reports.

The Brewers placed Hall on the 15-day injured list Sunday due to a left knee sprain.

Hall escaped with a no-decision in Saturday's 11-5 win over the Orioles, coughing up five runs on eight hits -- including three home runs -- and a walk over 3.1 innings. He struck out four.

Hall didn't factor into the decision Saturday, giving up two runs on six hits and a walk over four innings in a 7-6 win over the Mets. He struck out one.

Hall started Friday's exhibition contest and gave up two earned runs over 2.0 innings while allowing five hits and posting a 3:1 K:BB.

Orioles general manager Mike Elias said Thursday that the team still views Hall as a starter long term, Andy Kostka of TheBaltimoreBanner.com reports.

Hall (3-0) allowed an unearned run and struck out one over two-thirds of an inning to earn the win Tuesday over the Astros.

Hall was recalled by the Orioles on Saturday, Andy Kostka of TheBaltimoreBanner.com reports.

Hall, who was building up arm strength at the Orioles' spring training facility in Florida, is back with Triple-A Norfolk and will work out of the bullpen initially, Danielle Allentuck of TheBaltimoreBanner.com reports.
