In what could be the first of several trades on deadline day, the Orioles sent right-handed pitcher Shawn Armstrong to the Tampa Bay Rays for cash considerations.
Less than two hours before the deadline, they acquired left-hander Ryan Hartman on waivers from Houston. He pitched in one game for the Astros this season, allowing one run on three hits in 2 1/3 innings to the Orioles on June 30th at Minute Maid Park.
Armstrong, who had an 8.55 ERA in 20 games with the Orioles before being outrighted to Triple-A Norfolk, was 1-3 with a 3.18 ERA in 15 games with the Tides.
In three seasons with the Orioles, the 30-year-old Armstrong was 3-0 with a 5.34 ERA and four saves.
Armstrong is 4-2 with a 4.65 ERA in seven seasons with the Orioles, Cleveland and Seattle.
Hartman, who was drafted by Orioles executive vice president/general manager Mike Elias in the ninth round of the 2016 draft, is 27 and started 12 games this season for Triple-A Sugar Land. He was 3-3 with a 5.03 ERA in 13 games this season.
The Orioles will see if there’s interest in some of their other relievers, principally left-handers Paul Fry and Tanner Scott. Right-handers Cole Sulser and Dillon Tate also could draw interest. The trade deadline is at 4 p.m.
