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.
Zach Putnam landed on the disabled list late last week due to right shoulder inflammation, which leaves Petricka as the clear favorite for saves with the White Sox. Armed with a mid-90s fastball, a changeup, and a slider, the 26-year-old right-hander has posted a 2.06 ERA over 43 appearances this season. His control has gotten better as the year has moved along and he has averaged nearly a strikeout per inning over the past two months. Thanks to his sinker, he's also inducing ground balls more than 60 percent of the time. Putnam expects to return as soon as he's eligible and Matt Lindstrom is ahead of schedule from ankle surgery, but Petricka has a chance to run away with this job with a solid showing. At the very least, he should be the man in Robin Ventura's bullpen for the next 10 days or so. There's no reason he should be out there in 80 percent of Yahoo leagues right now.
