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.
The Mets have been on a remarkable roll over the past month and they have received key contributions from some unexpected sources along the way. In addition to the useful starts from Seth Lugo and Robert Gsellman, Rivera has stepped up by batting .338 (22-for-65) through his first 22 games in the majors. With Neil Walker and Wilmer Flores sidelined, he has started six straight games at second base while collecting three homers and a double. The 27-year-old has hit at every level in the minors and won the PCL batting crown this year after putting up a .353/.393/.516 batting line in Triple-A. Obviously you have to take those Vegas numbers with a grain of salt, but he’s worth a look in deeper formats as long as the playing time is there.
