Fantasy Baseball Waiver Wire Picks: 6/12/26

Welcome to the Waiver Wire Picks, our daily fantasy baseball article that looks at the best players in baseball that you should be adding to your rosters. We’ll look at the players that are likely to be available in most leagues, as well as some deep league waiver wire options, and we’ll also look at the most added players in fantasy baseball across the major sites, and let you know which players to add and which you can leave on the wire.

Top Priority Players to Add

Braden Montgomery (CWS) – OF (Yahoo – 36%)

Playing Single-A ball just over a year ago, Montgomery’s been on a rocket ship to the Majors. But a 152 WRC+ will do that, as will a .314 combined batting average and a 15.1% Walk rate to go with it. Overall, he’s been barnstorming the Minors, with 22 homers and 19 steals dating back to last season across multiple levels, but there might actually be more power in that bat. ICYMI, Montgomery blasted a walkoff homer in his very first game in the Majors (where he just kind of flicked the ball to the opposite field, which was impressive in it’s own right). Given his speed and power combination, this switch-hitter is easily the top add this week and should be owned everywhere. And if you’re in one of those points leagues that counts wild stats like Outfield Assists, Braden’s got a cannon for an arm and should throw out plenty of baserunners.

Dustin May (STL) – SP  (Yahoo – 32%)

Dustin May has been through some stuff. After Tommy John in 2021, he had a tear in his esophagus a couple of years later and lost forty pounds. He managed to come back and throw 130 innings last season, but had some diminished velocity (and effectiveness). Now, though, he’s put some of the weight back on (and is apparently is no longer eating salads, which caused the freaky throat injury in the first place). After a couple of really bad starts where he gave up a combined 13 runs to open 2026, May’s been steadily improving and is coming off a six-inning, six-K performance against the Mets where he allowed zero runners past second base. He’s also improving in the swing-and-miss metrics with 31 K’s in his last four outings and just five walks. Don’t let his 4-6 record fool you, May is a solid pickup.

Alex Lange (KCR) – RP (Yahoo – 24%)

This one’s less about the skills and more about the opportunity, but I do find Lange intriguing. With Lucas Erceg struggling, Lange’s picked up a Save in four of his last five appearances. Though some of his metrics are middling (or downright bad), he’s put it together over the last six weeks. He had a 2.38 ERA and 1.06 WHIP in May, and has ten K’s in his last six innings (he also has five walks). He’s got an 89th-percentile Whiff rate, so the strikeouts could pile up, but a second-percentile Barrel rate also means the hits could do the same. Still, he’s a former first-rounder with some closing experience in Detroit, and though his Walk rate has been well over 10% for his career, he seems to find ways to pitch around those free passes. He’s a tentative add for me if you need Saves, especially since the Royals often find themselves in close games.

Yahoo and ESPN Most Added Players

Yahoo!

Hunter Dobbins is a surprise to see at the top here, given his track record of never lasting more than five innings in an appearance. His last (and best) start of the season came against the Reds, where he struck out six and gave up zero runs, but that’s not an outing I’d call revelatory. Dobbins throws hard and has a decent K-rate of 26%, and he also serves up a fair amount of ground balls (53%). But his Walk rate is a poor 13.2% and he’s getting barreled 15% of the time. His ERA and xERA are nearly two runs apart.

The names that follow Dobbins are much more interesting. Cags might just have turned the corner to becoming not just a solid big-leaguer, but a force. The former #6 draft pick has insane metrics (58.7% Hard-hit rate, which is 99th-percentile), but he’s got a Whiff rate that has echoes of Joey Gallo. That said, after three multi-hit games in a row, his average is up to a more-than-respectable .279. He still only has eight homers on the year since he’s had issues lifting the ball, but he could easily start cranking them out of the yard with a couple of adjustments. Whatever he’s doing right now, though, is working just fine. And it looks like the Royals have rewarded his hot bat with a cleanup spot in the order, moving Vinnie P down in his stead.

Christian Scott has also had a solid run. Though he’s an extreme fly-ball pitcher (his ground-ball rate is just fourth-percentile), hitters are only averaging 87.1 mph off the bat against him, keeping those fly balls in the yard. Christian’s throwing mostly fastballs and sweepers, and there’s a near-15 mph difference between the two pitches, keeping hitters off balance. He’s well worth streaming in solid matchups.

Braden Montgomery was mentioned above, but if he’s somehow still on the wire in your league and you’re not convinced, this might be your last chance to grab him.

And Martín Pérez might have trouble cracking 90 mph on his fastball in his age-35 season, but he plays for the best team in baseball and has a 3.02 ERA. I think the matchup against the White Sox (which was rained out) probably didn’t suit him very well, but he’ll draw the Mets instead on Friday and that should work better for him.

ESPN

Montgomery is the top guy on ESPN’s most added list, so finally we’re seeing some respect here. Cags and Christian Scott switch places in the second and third slots, which I don’t have a problem with, as Caglianone’s 30+% K-rate should make the points-league-friendly ESPN crowd more dubious of his success.

And while he’s already owned in seven of ten fantasy leagues, Justin Wrobleski gets the nod in fifth place. Wrobleski’s been featured in this column before, mostly due to his unusual self-evaluation tactics after his starts. But after an April where he had a 0.69 ERA, he’s been shakier since. Still, he plays for the Dodgers and should net opportunities for W’s (with seven in just eleven starts, he’s fifth in the NL). With LA’s six-man rotation, though, I might start phasing him out of my teams, especially in a points league.

Streaming Pitchers

Check out Nick Pollack’s SP Streamer Rankings for the complete breakdown on every start for the next few days. There are two pitchers to highlight.

Shane Baz (BAL) – SP (Yahoo – 56%) vs SDP

The Padres are dead last in MLB when it comes to scoring runs. They’re also the worst in batting average and OBP. Baz has already been in a nice stretch where he’s turning around a rough couple of months, getting better shape on his knuckle-curve and spotting his fastball effectively. He racked up nine K’s in his best outing on May 26, then followed it up with a quality start and Win in Fenway. He didn’t fare as well in his last outing against the Blue Jays, but with the Padres hitting the way they are, he should coast. Here’s how his last three starts compare to the rest of his season:

Trevor McDonald (SF) – SP (Yahoo – 11%) vs CHC

The Cubs looked like a top-tier offense at the beginning of the season, but they’ve scored just 3.3 runs per game since May 9 and lost 15 of their last 20. McDonald gets them in a rematch on Saturday after facing them at Wrigley last week. He fared well in that one, but got a little wild and inefficient and lasted only five innings. But he did rack up a half-dozen K’s.

Aside from a blow-up outing against the White Sox, McDonald’s looked solid, with just eleven runs allowed in six starts. Four of those six have been road games, including appearances at Dodger Stadium, the Sacramento Small Park, and Milwaukee—so a home game should be welcome. Look for McDonald to have a good outing and he can put up solid ratios the rest of the year, especially with a 99th-percentile Ground-Ball rate.
