Fantasy Baseball Waiver Wire: Week 18
July 31, 2017 | Matt Terelle
Welcome to Week 18 of the MLB season. Today we will take a look at the waiver wire in your fantasy baseball league and make recommendations based on MLB risers. For this series, I will be using ownership percentages from Yahoo! leagues. Generally speaking, I will be looking for players who are less than 50% owned, but there are times where I may target someone who is slightly over the ownership threshold if he is a must-own in leagues.
Please note, all statistics and ownership percentages are from Monday, July 31. Let’s get started!
Trevor Rosenthal (STL) – 44% owned
Rosenthal appears to have reclaimed the closer role in St. Louis and has looked like the 2015 version of himself when he racked up 48 saves and posted a 2.10 ERA. The veteran right-hander has picked up two saves over the past three days while also notching seven strikeouts in three innings over that span. He’s worth an add if you need to tally a few extra fantasy saves.
Welington Castillo (BAL) – 47% owned
Castillo has heated up at the plate lately, posting a .419 batting average, one homer, five runs, and six RBI over the past 14 days. His season-long numbers are solid, as well, with him hitting .280 with 10 homers and 32 RBI. Castillo has always been an above-average offensive catcher and, provided he remains healthy, is primed to put up a solid final two months of the season playing in hitter-friendly Camden Yards.
Gerardo Parra (COL) – 44% owned
Parra just continues to hit since returning from the DL on July 7. The first baseman/outfielder has posted a .443 batting average, two homers, 13 runs, and 17 RBI over that span. Considering his recent hot streak and the fact he plays his home games in offense-friendly Coors Field, Parra should be on your radar in fantasy leagues.
Cory Spangenberg (SD) – 19% owned
Spangenberg, a former first-round pick, has put together a solid month for the Padres. The 26-year-old is hitting .309 with four homers, 17 runs, 14 RBI, and one stolen base over that span, providing a lift for the Padres. Spangenberg also has eligibility at third base and the outfield, giving fantasy owners some flexibility with him.
Rafael Devers (BOS) – 42% owned
Devers, considered one of Boston’s top prospects, has delivered results through his first five MLB games. In 20 at-bats, Devers has two homers, four runs, and three RBI while hitting .300. It’s still early, but Devers has the talent to be a huge difference maker for your fantasy team down the stretch. He won’t be this widely available next week if he continues to hit like he has so far.
Wilmer Difo (WAS) – 5% owned
Difo has filled in admirably for the injured Trea Turner. While he doesn’t offer the game-changing base stealing ability that Turner did, and few players can, Difo has posted a robust .391 batting average to go along with three homers, 17 runs, 11 RBI, and two steals over the past 30 days. With Turner still a few weeks away from returning, look for Difo to remain a regular in the Nationals’ lineups until then.
Bradley Zimmer (CLE) – 35% owned
Zimmer has been an impressive five-category producer for the Indians this season, posting a .279 average, seven homers, 29 runs, 35 RBI, and 13 stolen bases in 204 at-bats. He’s been exceptionally hot over the past week, batting .417 with two homers. He should remain a solid fantasy contributor across the board for the remainder of the season.
Manuel Margot (SD) – 21% owned
Margot is finally starting to show the potential that made him the centerpiece of the trade that brought star closer Craig Kimbrel to the Red Sox before the start of the 2016 season. Margot is hitting .281 this season with eight homers, 29 runs, 23 RBI, and 11 stolen bases in 288 at-bats. He’s really picked up the pace over the past month, batting .310 with four homers and four steals.
Thanks for reading, good luck this week!
