Lance Pendleton is a Rule 5 draft pick who is competing for the final spot in the rotation. Pendleton was acquired from the Yankees and has spent the past three seasons in the Yankees' minor league system. He could quickly become a fan favorite with the Astros, as he grew up nearby Houston and has been a lifelong fan.
The question is if the Astros believe Pendleton can compete at the major league level for the whole season, or they will need to offer Pendleton back to the Yankees for $25,000. Pendleton has had an up-and-down spring training so far. In his first appearance, he pitched one scoreless inning, only giving up one hit.
However, he struggled in his last appearance yesterday, walking in the winning run against the Yankees. I wouldn't hold it too much against him though, as he did enter in a tough situation and wasn't expected to pitch yesterday, but was called on due to the situation.
