Tuesday's Fantasy Baseball Drop Candidates Include Luke Weaver and Mark Vientos

After going over some more fantasy baseball waiver wire targets (hitters and pitchers), let's go over our second round of drop candidates for the week.

We won't cover anyone who appeared in the Monday drop story.

More droppable player data can be located on the waiver wire trends most dropped tab, which can be found on any fantasy baseball page here at FantasySP.

Should You Drop Luke Weaver?

Weaver is owned in 76% of leagues right now, but is down 6.6% today. He's bound to be dropped in more leagues as he's expected to miss between 4-6 weeks with a hamstring injury.

Weaver has been the team's closer after Devin Williams struggled mightily earlier in the season. Weaver has appeared in 24 games and covered 25 2/3 innings for the Yankees this season, and he has a 1.05 earned run average.

He's allowed three runs on 11 hits and seven walks, while striking out 24 batters. Weaver is 1-1 with eight saves, one blown save and six holds.

Weaver got to about 85% rostered, and was inching toward 100%, but the injury will definitely set him back. If you don't have an IR spot to throw him in, Weaver is going to get dropped in a bunch of redraft leagues.

Fantasy relievers are hard to come by, so dropping a top-end option like Weaver hurts. He's simply out too long to keep rostering in redraft leagues through his time out though.

I'd drop Weaver in any standard redraft leagues, if there's no IR spot to throw him in. Depending on how deep a league you are in, Weaver could be stashed on your bench until he returns to the field. Just make sure your fantasy team isn't suffering by burning a roster spot before making that decision.

Weaver will be a big-time waiver pickup when he's nearing a return, so keep a close eye on his status.

Should You Drop Mark Vientos?

Vientos is owned in 59% of leagues right now. He got injured on Monday night, and the Mets calling up Ronny Mauricio likely means Vientos is headed toward an injured list stint.

I viewed Vientos as a big fantasy asset coming into the season, but he's struggled through May. Across 53 games and 208 plate appearances, Vientos has a .230 average and .298 on-base percentage.

Vientos also has 21 RBIs, 22 runs scored, 17 walks, no stolen bases and 49 strikeouts this season. He has six homers, a triple and eight doubles among his 43 total knocks.

If Vientos does indeed hit the injured list, standard redraft owners are likely to move on from him. I'd only keep rostering him in regular setups if there was an IR spot to throw him on.

I still like the idea of rostering Vientos in deeper redraft leagues, but depending how long he's out, he might become droppable in those leagues too. If your fantasy team is struggling, then you might also need his roster spot to remain competitive. In other words, Vientos is probably going to be dropped in a bunch of redraft leagues, especially if he's out an extended period of time.

Like Weaver, Vientos will be added back in a decent amount of redraft leagues when he's healthy again, so we'll need to keep a close eye on his status moving forward. Hopefully a little time off can help Vientos get back to his 2024 form for the second half of the 2025 season.

Should You Drop Marcelo Mayer?

Mayer is rostered in 31% of fantasy leagues right now. He was as high as 42% in late May.

He has just one single over his past four games and 16 plate appearances. Mayer has no RBIs or stolen bases over that stretch. He has scored once, walked once and struck out seven times in that span.

Mayer's first taste of the big leagues has gotten off to a rather slow start. In eight games and 32 plate appearances, he has six hits, including two doubles. Mayer has no RBIs or stolen bases, just two runs scored and walks and 10 strikeouts.

He did not start on Monday against a left-handed pitcher. Mayer hit fourth or fifth in the four games before that - Boston faced righties in each contest.

Boston faces another lefty on Tuesday, so Mayer may be on the bench again. He also could have been benched yesterday as a result of his poor results at the plate so far, and of late.

Not all prospects excel in their first taste of the big leagues, even the top-end hitters like Mayer. I still have high hopes for him in the long run, but he's just a deep-league option for redraft league owners out there.

Mayer should probably be benched until further notice. He needs to produce more at the plate before fantasy owners can trust him more.

He's still a player to keep tabs on, but he could be demoted back to the minor leagues if he doesn't pick things up soon. Definitely don't bail on Mayer in dynasty/keeper leagues, but most redraft owners can look elsewhere for help right now.

Should You Drop Nick Martinez?

Martinez was let go in 6.5% of leagues, bringing his overall mark down to 53%.

I've been a big supporter of adding Martinez in more leagues, but he was tagged for five runs over 4 2/3 innings against the Cubs on Sunday. That was his worst start of the season.

Over 12 starts, Martinez is 3-6 despite having a solid 3.89 ERA. He's covered 69 1/3 innings, allowing 31 runs (30 earned) on 66 hits and 15 walks - Martinez has 47 punchouts along the way.

His strikeout numbers are down of late, topping out at three over his past four starts. Martinez is averaging 1.2 Ks less per nine innings compared to a season ago. His ERA is 0.79 higher and his WHIP is up 0.14.

Martinez had pretty similar numbers to last year coming into his past two starts, but allowing eight runs on 13 hits and only striking out four over those starts has dampened his overall marks.

I still think Martinez is a pretty good deep-league fantasy asset, with standard league streaming value in the right matchups. The Cubs are not a team to test, and they showed why on Sunday.

Martinez has tough matchups against the Diamondbacks and Tigers coming up, so that's probably part of the reason why he's still being dropped today.

I'm backtracking on my views on Martinez. He's still a pitcher to try in deeper leagues for most of his starts, but until he ups his strikeouts or gets in a better groove in not allowing runs, standard league starts are going to be hard to come by.

I'd start Martinez in deeper leagues for his next two outings, but I'd look elsewhere in standard leagues.

Should You Drop Dylan Moore?

Moore is rostered in 47% of leagues after a 4.7% dropoff today.

He's hitless over his past four games, but more notably only has four plate appearances in that timeframe. Moore has started once over the last five Seattle games. The promotion of Cole Young has taken away a starting spot for Moore, who was already trending down.

Moore has appeared in 55 games this season, but has just 143 plate appearances. He's got a .264 average and .372 OBP, but that's way down from the .326 average and .392 OBP he had in mid-April.

Something still working in his favor is that he's appeared at first, second and third base, shortstop and right field this season. He's appeared in left field and center in the past, so it's possible he's eligible for every infield and outfield spot (just not catcher).

Still, if he's not playing or producing, Moore isn't a very good fantasy asset. He shouldn't be rostered in any standard redraft leagues anymore, and the leagues only slightly deeper than standard setups should also be dropping Moore too.

Moore is worth holding for a bit longer in some deep redraft setups. If he continues to not start or play much, then he'll probably be dropped in most of those leagues by this time next week.

It might take an injury for roster shakeup for Moore to get his fantasy relevance back. Don't be afraid to move on from him if you see a waiver wire target you really like.
