Hao-Yu Lee, the Detroit Tigers' No. 6-rated prospect, made his big-league debut at Fenway Park on Friday after being called up from Triple-A Toledo. Lee, a 22-year-old infielder, went 0-for-3 with an error in the game, but manager AJ Hinch said he thought Lee 'handled himself well' on the big stage.

Why it matters

Lee's debut is an exciting moment for the Tigers organization as they look to develop their next wave of young talent. The team is facing a stretch of games against left-handed starters, making the right-handed hitting Lee an important piece of the lineup in the coming weeks.

The details

Lee was with the Toledo Mud Hens on Thursday night when he got the call to join the Tigers in Boston. After initially thinking he was in trouble, Lee was told that he would be starting at third base the next day at Fenway Park. Despite some early jitters, Lee said he was 'more focused than nervous' during the game. He hit one ball hard to the wall in right-center but finished 0-for-3 with an error on a high throw to first base.

What they’re saying

“My initial thought was, 'Oh, did I do something wrong?' Something major must've happened. I must've done something and my manager is going to scold me. I was pretty nervous.”

— Hao-Yu Lee, Tigers prospect

“I was pretty excited. It was pretty tough to go to bed. When normal people check into a hotel super late, their first thought is, I need to go to bed. I don't know why, but I just opened up my travel bag, took out a bat and started swinging.”

— Hao-Yu Lee, Tigers prospect

“I was more focused than nervous the whole game. I didn't want to be the guy who cost the team the win. Yesterday's performance defensively wasn't on par with my expectations. I'm going to make sure I keep grinding and practicing to make sure that doesn't happen again.”

— Hao-Yu Lee, Tigers prospect

“That's a big stage and I thought he handled himself well.”

— AJ Hinch, Tigers manager

What’s next

The Tigers will face six left-handed starters in the next 12 games, so the right-handed hitting Lee is expected to be back in the lineup on Sunday against lefty Garrett Crochet.

The takeaway

Lee's big-league debut at Fenway Park is an exciting milestone for the Tigers' top prospect, who has dealt with an injury-plagued spring. Despite some early jitters, he showed poise on the big stage and will look to build on this experience as the Tigers navigate a stretch of games against left-handed pitching.
