The Orioles added to their roster by recalling pitchers Branden Kline, Tanner Scott and outfielder Dwight Smith Jr. from Triple-A Norfolk on Sunday. They also activated pitcher Shawn Armstrong from the 10-day injured list.

Kline, a 27-year-old right-hander, has spent considerable time with the Orioles this season. He’s 1-4 with a 7.44 ERA in 25 games and was 1-1 with a 6.86 ERA in 18 games with Norfolk.

Scott, a 25-year-old left-hander, was 1-0 with a 5.29 ERA in 15 games with the Orioles and  3-4 with a 2.98 ERA and seven saves in 28 games at Norfolk. Scott has struck out 57 in 45 1/3 innings with the Tides.

Smith, who had been on the 10-day injured list with a left calf injury, was optioned to the Tides after his rehab assignment so that DJ Stewart could get more playing time.

In 84 games with the Orioles, Smith is hitting .238 with 12 homers and 48 RBIs and in 11 games, hit .311 with three home runs and 12 RBIs in 11 games at Norfolk.

Armstrong, who had a right forearm strain, has a 5.01 ERA in 39 games.

More callups are expected after Norfolk’s season concludes on Monday. Catcher Austin Wynns and designated hitter Mark Trumbo are likely additions.

Trumbo, who is on a rehab assignment, is 4-for-20 (.200) with two homers and six RBIs in his last five games. He’ll decide if his right knee is strong enough to play.

The Orioles will also make a final decision on Ryan Mountcastle, the International League Most Valuable Player.

If Trumbo or Mountcastle is activated, room must be found on the 40-rman roster.
