Jackson Holliday is one of baseball's most exciting prospects, but that doesn't mean he's infallible. His brief stint with the Baltimore Orioles proved that, as he struggled and was sent back down. Now that he is back in Triple-A, the struggle didn't completely end.It's rare for a position player to ever take the mound, but that is what embattled former infielder David Fletcher is doing. In one of the more unique matchups this baseball season, Fletcher struck out Holliday.Fletcher is not a natural pitcher, as he played infield with the Los Angeles Angels. He is converting to pitcher and even using a knuckleball during the season. He now has a pretty good resume-builder for his hurling: a strikeout of one of the top-hitting prospects in the MLB.It's impressive for Fletcher, who is in the Atlanta Braves system right now. It's a little less so for Holliday, and fans let him hear it on social media."Jackson is cooked bro," one said."Position player on the bump striking you out is insane," another stated."This is not surprising," one said."Biggest bust in baseball history. He’ll never step foot on a major league field again," one fan claimed.Holliday had plenty of struggles in the major leagues, but he didn't draw as much reaction from fans as he did with this strikeout.Jackson Holliday had a tough stint at the MLB levelJackson Holliday's ascension to the MLB level was not surprising. Even at 20 years old, the young player had flown through the minors and was hitting extremely well in Spring Training.Jackson Holliday had to go back to the minor leaguesAfter spending a little while longer in the minors, the Orioles finally called him up to start at second base. Unfortunately, it did not go to plan. In 10 games, Holliday hit just .059.He had a -49 wRC+, which means he was 151% worse than the average hitter. He had a 50% strikeout rate and a 5.6% walk rate. He just could not get anything going, so the Orioles pulled the plug and sent him back down.He had been tearing it up at the Triple-A level, but there's a distinct gap between that and MLB competition. Holliday will eventually be back, and he and the Orioles will hope he doesn't repeat his first stint's level of success.
