MLB's new ABS Challenge System has been used several times already this season, but Sunday's Minnesota Twins-Baltimore Orioles matchup had the first ABS-related ejection. 

Orioles closer Ryan Helsley faced Twins designated hitter Josh Bell with an 8-6 lead, a runner on first, and one out in the top of the ninth inning. Bell worked a 3-2 count before a slider on the outside corner was called ball four by home-plate umpire Chris Segal. Helsley tapped his hat to challenge the call after Bell started jogging to first, and Baltimore won the challenge, earning it a strikeout.

Minnesota manager Derek Shelton came out to argue and was eventually tossed by Segal. The former Pittsburgh Pirates skipper explained why he was upset postgame, via The Baltimore Sun's Matt Weyrich.

"I didn’t think Helsley tapped his cap quick enough," he said. "Maybe he did, maybe he didn’t, but I didn’t feel he did. I feel like it’s gotta be something within the three seconds, and I didn’t think it was there. But the umpiring crew thought it was."

Players are supposed to signal for challenges immediately if they wish to use one. Helsely said that Segal didn't see him tip his cap the first time, via MLB.com's Jake Rill.

"I mean, I understood where he [Shelton] was coming from because I had felt like the umpire didn't see me right away, and so I was kind of confused," the right-hander said. "And then, I think I did it again. But [second-base umpire] Laz [Diaz] behind me kind of took up for me and was like, 'He did it right away,' which, I know we're probably going to go through some growing pains with this because it's so new, and I think we saw that today."

"I can respect Shelton for trying to not get him to do it there, because it did seem like it was a little long in that moment," he continued.

As Helsley said, players, umpires, and managers must all adjust to the technicalities of ABS. Shelton's ejection was a sign of the times, as managers argued and got thrown out for disagreements with the actual calls rather than ABS details before this year.

After Bell struck out, catcher Victor Caratini reached base on an error by Orioles shortstop Gunnar Henderson, and second baseman Luke Keaschall went from first to third. That put the go-ahead run at home plate when pinch-hitter James Outman came up, but he flied out to left to end the contest.

Minnesota's six runs were more than it scored across the first two games of the series, as it lost 2-1 in Thursday's Opening Day matchup before winning 4-1 on Saturday. Left fielder Trevor Larnach opened the scoring with an RBI infield single in the second before shortstop Tristan Gray hit a three-run double in the same frame. 

Twins starting pitcher Bailey Ober tossed three scoreless innings before giving up a three-run homer to Orioles right fielder Tyler O'Neill in the fourth. Minnesota's bullpen couldn't bail the right-hander out, as center fielder Dylan Beavers then hit a two-run double in the sixth.

Twins third baseman Royce Lewis then tied the game 5-5 with a solo homer to left in the seventh, giving him back-to-back games with a homer. After that, Baltimore tallied three runs in the bottom frame, and Gray's eighth-inning RBI single was the last scoring play.

The silver lining is that Minnesota's offense has rebounded since getting just one extra-base hit on Opening Day. Plus, the pitching staff had quality outings in the first two contests.

Up next for the Twins is a road series against the Kansas City Royals before opening their home slate against the Tampa Bay Rays.
