The New York Yankees have sent Luis Severino to Triple-A to regain the form he showed in a brief Major League stint last season.

Severino, who had a 2.89 ERA in 11 starts last year, has a 7.46 ERA in 2016.

It can take time for a pitcher to fully adjust to the Major Leagues, something Joe Girardi believes is hampering his young pitcher.

"This is not unusual," Girardi said. "This is not abnormal. I'll bring up a name right here we saw -- Roy Halladay. He got sent back down because he struggled. He figured it out and was pretty darn good. This is not unusual. This is part of the progress for young players."

As a 22-year-old in 1999, Halladay went 8-7 with a 3.92 ERA. In 2000, he was 4-7 with a 10.64 ERA, appearing lost.

"When you are looking at Luis, you are looking at long term," Girardi said. "Long term, we have to get things straightened out. This isn't a guy who is 34 or 35, who has a long track record. This is a kid with a lot of talent. We want, the next time he comes up, to be a finished product. He came up last year -- and some of it was based on need -- and did very well. Sometimes when you enter your second season you have to make adjustments more than you ever had to make. It is not always so easy. He'll get through this."
