Billy Butler making his Yankees' debut Thursday

New York Yankees designated hitter Billy Butler is in the lineup batting fifth for his Yankee debut on Thursday.

What It Means:

The Yankees signed Butler on Wednesday night, and expect to play him at designated hitter in matchups against left-handed pitching down the stretch.

The 30-year-old Butler has struggled against southpaws this year, slashing only .262/.316/.369 with a .294 wOBA through 114 plate appearances.
