The Oakland Athletics are calling up top prospect Jesus Luzardo.

The left-hander is expected to join the club when they begin a series against the Houston Astros on Monday.

Luzardo would likely have debuted earlier, but he was sidelined by both a shoulder strain and then a lat strain in the early part of the season.

He has only pitched 43 innings this season.

The Athletics currently hold down the American League's second Wild Card.
