Last winter’s Rule 5 draft was relatively busy, as 15 players were selected across 14 teams. Not all of those players broke camp, so we’ll check in on the class to see which draftees impressed enough in Spring Training to make their major league debuts.

A quick refresh for those unfamiliar with the process: the Rule 5 draft is a means of getting MLB opportunities to players who might be blocked with their current organization. Teams can draft certain players who are left off their original club’s 40-man roster. The drafting team needs to keep that player on the MLB roster or injured list for their entire first season. If they do so, they’d gain the player’s contractual rights permanently. A team can keep an injured Rule 5 pick on the major league IL, but they’d eventually need to carry him on the active roster for 90 days. If the player misses the entire season, the Rule 5 restriction carries over to the following year.

If the drafting team decides not to carry the player on the roster at any point during the year, they need to place him on waivers. If he goes unclaimed, the player is offered back to his original organization — which does not need to carry him on either the MLB or 40-man rosters to take him back.

On An Active Roster

Shane Smith, White Sox RHP (selected from Brewers)

Smith not only made Chicago’s roster, he cracked the Opening Day rotation for the rebuilding club. Most of the time, teams keep Rule 5 pitchers in low-leverage relief until they build enough of a regular season track record to be entrusted with more meaningful innings. The White Sox are giving Smith a rare amount of responsibility right out of the gate.

Some of that is on the team, of course. They’re coming off the worst season in modern history and expected to be one of the three worst teams in MLB this year. Their Opening Day starter, Sean Burke, entered the year with 20 days of major league service. Still, Smith has put his best foot forward in securing that rotation spot. He worked 10 2/3 innings of four-run ball during Spring Training, striking out 11 against four walks. Smith has managed a pair of quality starts within his first three regular season outings. He has only given up four runs across 17 2/3 frames, a 2.04 earned run average.

The 6’3″ righty will need to improve upon his 12:7 strikeout-to-walk ratio. He’s getting ground-balls at an excellent 52.1% clip, though, and a four-pitch mix led by a 94-95 MPH fastball is intriguing. He’s not in any danger of losing his roster spot anytime soon.

Liam Hicks, Marlins C (selected from Tigers)

Hicks, a lefty-swinging catcher, went from the Rangers to the Tigers in last summer’s Carson Kelly deal. While he reached base at a .414 clip in Double-A after the trade, Detroit opted not to add him to the 40-man roster. The rebuilding Marlins grabbed him to back up Nick Fortes, buying more time for highly-regarded prospect Agustín Ramírez to play at Triple-A.

Plate discipline has been Hicks’ calling card in the minors. He had more walks (seven) than strikeouts (six) during Spring Training, though he only hit .200 with one extra-base hit in 40 plate appearances. He broke camp and has hit .214 with two walks and six strikeouts in 35 trips to the plate. His lone extra-base knock is a double. Opponents have stolen seven bases in eight attempts over his 74 innings behind the dish.

It hasn’t been a great start, but Hicks doesn’t seem in jeopardy of getting squeezed off the roster in the near future. Fortes, who is probably better suited as a backup himself, went on the injured list with an oblique strain last week. The Fish called up journeyman Rob Brantly in his place. Hicks got the start in two of the three games over the weekend. He’s the primary catcher for now. Ramírez should get a look fairly soon, but Hicks has a bit of run to show he should stick around as the backup.

Garrett McDaniels, Angels LHP (selected from Dodgers)

McDaniels had made two appearances above A-ball — totaling three innings at Double-A — when the Angels plucked him out of the Dodgers’ system. He showed an impressive combination of strikeouts and ground-balls in the lower minors that intrigued the Halos. The grounders have remained against high-level hitters, though the whiffs have not. McDaniels got grounders on more than two-thirds of batted balls over nine Spring Training innings. He jumped a couple more experienced southpaws on the bullpen depth chart to break camp despite four strikeouts and walks apiece.

The 6’2″ lefty has been hit hard through his first few MLB appearances. McDaniels has allowed four runs (three earned) over 5 2/3 innings. He has given up seven hits and issued five walks while recording five punchouts. He’s still getting a ton of worm-burners. Twelve of the 17 batted balls he’s allowed have been grounders. They’ve mostly been hit hard, though, and one of the two fly-balls he has given up was a Yainer Diaz grand slam.

Noah Murdock, Athletics RHP (selected from Royals)

Murdock, a 6’8″ righty, has been a ground-ball machine throughout his minor league career. He got grounders at a huge 59.7% clip over 62 2/3 innings between the top two minor league levels last season. That continued into Spring Training, as he kept the ball on the ground at a 70.4% rate en route to a 3.86 ERA over 11 2/3 innings.

That earned Murdock a bullpen spot and a handful of relatively high-leverage assignments from skipper Mark Kotsay. It’s been a shaky start. Murdock has allowed eight runs through 8 2/3 frames, largely because of 10 walks. Most of the damage came in one dreadful appearance against the Cubs, where he gave up six runs in one inning. Murdock has managed scoreless appearances in four of his five other outings, but he has walked at least one hitter in all but one of those games. He’ll need to find the strike zone more consistently to stick all season.

Gage Workman, Cubs IF (selected from Tigers)

Workman had never played above Double-A, where he struck out at a lofty 27.5% rate. His combination of power, speed and defensive ability nevertheless led the Cubs to add him. Workman mashed his way onto the Opening Day roster with a .364/.420/.705 line and four homers over 20 games this spring.

The Cubs haven’t been able to find him much playing time. He has started only started two of their first 19 games, both at third base. Workman has two hits and a walk with five strikeouts over 10 plate appearances. The Cubs might not be able to use a bench spot like this all season.

Mike Vasil, White Sox RHP (selected from Mets via Rays and Phillies)

Vasil landed with the Rays via a Rule 5 draft day trade with Philadelphia. Tampa Bay waived the UVA product a couple weeks into Spring Training. The White Sox claimed him to prevent him from being returned to the Mets organization. Vasil joined Smith as the second Rule 5 pick on the Sox’s roster. He’s working in the mop-up spots typically associated with Rule 5 draftees. In four appearances, Vasil has reeled off nine scoreless innings. He has only managed six strikeouts against four walks and a hit batter. He’s coming off a 6.04 ERA over 134 innings in Triple-A.

Currently On Major League Injured List

Angel Bastardo, Blue Jays RHP (selected from Red Sox)

Bastardo underwent Tommy John surgery last June while he was in the Boston system. The Jays selected him knowing they’d stash him on the 60-day injured list for most or all of this season. That delays the decision on whether to keep him in the MLB bullpen, but he’d need to stick on the 40-man roster throughout next offseason and log at least 90 days on the active roster between this season and next for the Jays to get his contractual rights.

Nate Lavender, Rays LHP (selected from Mets)

It’s basically an identical scenario with Lavender, who underwent Tommy John surgery last May when he was pitching for the Mets. He’s perhaps a little more likely than Bastardo to make his return in the second half of this season. In any case, the Rays won’t need to make the decision for at least a few more months.

Connor Thomas, Brewers LHP (selected from Cardinals)

Behind a 53.5% ground-ball rate, the soft-tossing Thomas managed a sub-3.00 ERA over 56 Triple-A appearances a year ago. He had a solid spring, throwing 11 1/3 innings of four-run ball with 11 strikeouts and five walks. Thomas broke camp in low-leverage relief. He was hit hard in his first two MLB appearances. The Yankees teed off for eight runs (including a trio of homers) over two innings in his debut. Thomas gave up four runs in 3 1/3 frames against the Reds a week later. The Brewers placed him on the IL with elbow arthritis after the latter appearance. A return timeline is unclear.

Returned To Original Organization

Evan Reifert, RHP (returned to Rays from Nationals)

Refiert is a slider specialist with well below-average command. He walked 12 batters in 6 1/3 innings during Spring Training, so the Nats returned him to the Rays a couple weeks before Opening Day. Tampa Bay assigned him to Triple-A Durham for his first stint at that level.

Cooper Bowman, 2B (returned to A’s from Reds)

A righty-hitting second baseman, Bowman got a brief look in camp from the Reds. He had three hits (all singles) in 25 Spring Training at-bats before Cincinnati decided he wouldn’t make the team. The A’s assigned him to Triple-A Las Vegas, where he has begun the season on the injured list. Bowman struggled in Triple-A last season but has hit well up through Double-A.

Eiberson Castellano, RHP (returned to Phillies by Twins)

Castellano was trying to make the jump directly from Double-A, where he’d turned in a sub-4.00 ERA with a 31.3% strikeout rate last season. He didn’t command the ball well enough in camp to crack the Twins’ pitching staff, however. Castellano walked 10 batters and surrendered 10 runs over 10 2/3 innings. Minnesota returned him to the Phillies, who assigned him back to Double-A Reading. He’s pitched there once so far, firing three perfect innings with five strikeouts.

Anderson Pilar, RHP (returned to Marlins by Braves)

Pilar is another Rule 5 pick whose command was an issue in camp. He walked six batters over 5 2/3 innings, giving up nine runs in the process. Atlanta returned him to the Marlins, who assigned him to Triple-A Jacksonville. Pilar has been fantastic in the early going there, striking out nine without issuing a walk over 5 2/3 scoreless innings. If he continues at anything like that pace, he should get a look in Miami’s bullpen before much longer.

Juan Nuñez, RHP (returned to Orioles by Padres)

Nuñez, who had never pitched above High-A when he was selected, always had an uphill battle to cracking a win-now roster in San Diego. Six walks over five Spring Training innings ensured he’d be offered back to the Orioles. He’s making his Double-A debut this season. Nuñez has fanned three in two scoreless innings.

Christian Cairo, SS (returned to Guardians by Braves)

Atlanta was the only team to make two Rule 5 selections. They returned Cairo to Cleveland at the same time they offered Pilar back to the Marlins. Cairo is one of a number of contact-oriented middle infielders in the Guardians’ system. He hit .179 without a home run in 16 Spring Training games. Cleveland assigned him back to Triple-A Columbus, where he finished last season. He’s batting .250 with 12 strikeouts and four walks over his first 10 contests.
