It's an unexpected pain that seems to linger for a while.Acuna Jr. is no stranger to missing time due to injuries, which fans hope isn't the case here. He missed the 2021 season with a torn ACL, which hampered his performance a bit last season."Made of glass, this sucks," one fan tweeted.annoying dodger fan@dodgersbetter@MLBONFOX @BravesOnBally Made of glass, this sucks1@MLBONFOX @BravesOnBally Made of glass, this sucksDion. ⚾️🏀@HeyImDionmarlins ballpark clearly hates Acuña Jr twitter.com/mlbonfox/statu…FOX Sports: MLB@MLBONFOXRonald Acuña Jr. exits the game after fouling a ball off his knee in the 6th.(via @BravesOnBally) 27229Ronald Acuña Jr. exits the game after fouling a ball off his knee in the 6th.(via @BravesOnBally) https://t.co/NbmDsPNiJCmarlins ballpark clearly hates Acuña Jr twitter.com/mlbonfox/statu…Marcos Lopez@marcosl_3No no no please be ok twitter.com/mlbonfox/statu…FOX Sports: MLB@MLBONFOXRonald Acuña Jr. exits the game after fouling a ball off his knee in the 6th.(via @BravesOnBally) 27229Ronald Acuña Jr. exits the game after fouling a ball off his knee in the 6th.(via @BravesOnBally) https://t.co/NbmDsPNiJCNo no no please be ok 😭 twitter.com/mlbonfox/statu…Fans hope Ronald Acuna Jr. just left the game with some discomfort out of precaution.

It could not have been easy to finish the at-bat with the way he went down.Ronald Acuna Jr. has been playing out of his mindAtlanta Braves v Miami MarlinsRonald Acuna Jr. has been one of the season's hottest hitters. He leads the league in runs (28), hits (430), doubles (11), stolen bases (14), and total bases (72). The baseball looks like a balloon to him at the plate.He was just named National League Player of the Month for April. This is the second time he has won such an award. He's the first player to win the award since Austin Riley did in July of last season.Pitchers couldn't keep Acuna Jr. off the basepaths. He reached base safely in 26 of the 27 games he played in, getting a hit in 20 of those games. There truly was no better player in the league in April.Hopefully, he didn't do too much damage to his knee in Thursday's game. He's among the most exciting players since the season opened up. The game of baseball is better when Acuna Jr. is healthy. We'll have to watch for any updates from Atlanta's camp.
