The Orioles added six players to their 40-man roster on Friday. Four were expected and two weren’t. By selecting the contracts of the six, the Orioles have protected them from the Rule 5 draft.

The ones who were expected were left-handed pitchers DL Hall and Kevin Smith, right-handed pitcher Kyle Bradish and infielder Terrin Vavra. The two who weren’t were right-handers Félix Bautista and Logan Gillaspie.

They also acquired infielder Lucius Fox on waivers from Kansas City. He’s a 24-year-old native of the Bahamas and hit .245 with five home runs and 24 RBIs in 62 games, 57 with Triple-A Omaha. He stole 19 bases in 21 attempts.

The Orioles’ 40-man roster is at 39.

Hall, a 23-year-old left-hander, was the Orioles’ No. 1 draft choice in 2017. He began the season at Double-A Bowie but was limited to seven starts because of an injury to his left elbow. Hall was 2-0 with a 3.13 ERA. He struck out 56 and walked 16 in 31 2/3 innings.

Bradish, a 25-year-old right-hander, was one of four pitchers acquired from the Los Angeles Angels in December 2019 for starting pitcher Dylan Bundy. In 24 games, 22 starts at Triple-A Norfolk and Bowie, Bradish was 6-5 with a 3.68 ERA. He struck out 131  and walked 44 in 100 1/3 innings.

Smith, a 24-year-old left-hander, was picked up from the New York Mets in the August 2020 deal for relief pitcher Miguel Castro. In 22 games, 20 starts at Norfolk and Bowie, he was 3-7 with 4.59 ERA. Smith struck out 105 and walked 59 in 82 1/3 innings.

Vavra, a 24-year-old infielder, was acquired from the Colorado Rockies in an August 2020 trade for reliever Mychal Givens. He missed much of the season because of a back injury and hit .275 with five home runs and 21 RBIs in 48 games, 40 with Bowie.

Bautista, a 26-year-old right-hander, was 1-6 with 11 saves and a 1.54 ERA in 40 games for High-A Aberdeen, Double-A Bowie and Triple-A Norfolk. He struck out 77 and walked 30 while allowing just two home runs in 46 2/3 innings.

Gillaspie, a 24-year-old right-hander, was signed this spring after pitching in the Milwaukee Brewers organization in 2019. He was 1-3 with four saves and a 4.97 ERA in 26 games with Aberdeen and Bowie. He struck out 52 and walked 11 in 41 2/3 innings. He’s 0-1 with a 9.00 earned-run average in five games in the Arizona Fall League.

Among those who were left unprotected were right-handed pitcher Cody Sedlock, the Orioles’ top pick in 2016, left-handed reliever Nick Vespi, infielders Patrick Dorrian, Cadyn Grenier and Adam Hall, and outfielder Robert Neustrom.
