Welcome to Pickup of the Day, where every weekday we'll pick an under-the-radar player whose immediate value is on the rise. The idea here is to identify a starter who can give you some solid innings off the scrap heap, a talented backup who's been given a chance because of a starter's injury, an unheralded regular with a favorable matchup, or a potential breakout player who's starting to put it together. Unlike regular waiver-wire advice, Pickup of the Day is geared more towards interim success, but hopefully we'll have the intuition to help you snag a waiver-wire gem a few times this season.
While this isn't quite on the level of George Springer or Jon Singleton, the Astros have another prospect on the way to the majors who is worthy of your attention. Santana, who was acquired from the Phillies in the Hunter Pence deal in 2011, is expected to be called up from Triple-A Oklahoma City on Tuesday. And why not? Ranked as the organization's No. 8 prospect by Baseball America over the winter, the 21-year-old outfielder is batting .304/.383/.502 with 13 home runs and 52 RBI over 84 games this season. Strikeouts are an issue for him, so some struggles wouldn't be surprising during his first stint in the majors, but he has some pop in his bat and it won't take him much to be an improvement over what the Astros have gotten out of left field so far this season. He should be picked up in AL-only leagues and might be worth a try if you are looking for some power in deeper mixed formats.
