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.
Trevor Rosenthal failed to retire a single batter in blowing a save on Saturday against the Rangers. The hard-throwing reliever hasn’t been himself this season, posting a 4.91 ERA while walking a whopping 19 batters over 22 innings. Cardinals manager Mike Matheny hasn't indicated that he's ready to make a change yet, but Rosenthal's leash has to be short at this point. Seung Hwan Oh can’t be ruled out as a potential option to replace Rosenthal should the Cards make a change, but the most likely candidate might be Kevin Siegrist. The lefty holds a 2.89 ERA and 32/9 K/BB ratio over 28 frames this season and has recorded seven saves over the last two seasons while filling in in the ninth inning on days where Rosenthal wasn’t available.
