Roberto Osuna active ahead of Astros' opener

Houston Astros reliever Roberto Osuna is on the Opening Day roster.

What It Means:

Osuna will not start the year on the injured list but his availability for Friday's opener against the Seattle Mariners remains uncertain. The 25-year-old right-hander just started throwing off a mound this week after arriving late to summer camp workouts for an undisclosed reason. Ryan Pressly is expected to close for the Astros if Osuna isn't ready.

numberFire's models expect Osuna to notch 13 saves over 23 2/3 innings this season while recording a 3.43 ERA and 0.93 WHIP with 29 strikeouts and 5 walks.
