Fantasy Baseball Waiver Wire: A's, Rockies, Mariners offer plenty of streaming options in Week 15

We’re at the halfway point of the season, with most teams playing over 81 games at this point in the season. Among the top teams in adjusted score for team pitchers, most have high-end numbers across the board. The Phillies continue to be a strange team that allows a high BABIP, which can be seen via the individual pitcher numbers. Meanwhile, the Astros continue to overperform their underlying metrics, though they have Hunter Brown Back. Tatsuya Imai and Spencer Arrighetti have been pitching better, but it’s still a struggling rotation.

Here's a look at each team sorted by highest adjusted score for Week 15.Corbin YoungThough there have been quality pitchers in stretches from the Cardinals, Athletics and Nationals, most of the season-long numbers look the same, which makes them matchups to target for opposing hitters. We have another busy week, including nine teams with seven games and several playing in hitter-friendly ballparks.

Teams With Seven Games in Week 15Reds (4 at MIL, 3 vs. BAL)

The Reds will face five right-handed starting pitchers in Week 15. The two lefties will be in the early part of the week against Shane Drohan and Kyle Harrison.

• >Guardians (3 vs. TEX, 4 vs. CWS)

The Guardians project to face five right-handed starting pitchers in Week 15. MacKenzie Gore and Anthony Kay are the two lefties on the schedule.

• >Rockies (4 vs. MIA, 3 vs. SF)

Finally, the Rockies have all their games at home in Week 15. Better yet, seven home games against the Marlins and Giants, who have shaky starting pitchers. The Rockies project to face six right-handed starting pitchers in Week 15. Mickey Moniak is back from the injured list, meaning he should benefit as a strong-side platoon option. Other strong-side platoon options to note include Troy Johnston and Edouard Julien.

• >White Sox (3 at BAL, 4 at CLE)

There are five right-handed starting pitchers on the slate for the White Sox. Kyle Teel is back, and he should benefit based on the righty matchups. Andrew Benintendi and Tristan Peters can be deep-league considerations.

• >Dodgers (3 at ATH, 4 vs. SDP)

The Dodgers project to face five right-handed starting pitchers. The two lefties will be from the Athletics, including Gage Jump and Jeffrey Springs.

• >Marlins (4 at COL, 3 at ATH)

Like the Rockies, the Marlins will be hitting in hitter-friendly ballparks. The best pitcher they’ll face in Week 15 is Gage Jump. There are five right-handed starting pitchers on the schedule. Owen Caissie should benefit as their most fantasy-relevant strong-side platoon option. We could see Caissie hit a few home runs in Week 15.

• >Brewers (4 vs. CIN, 3 at ARI)

There are four right-handed starting pitchers on the schedule for the Brewers. Jake Bauers, Sal Frelick and David Hamilton have been the strong-side platoon options. They’ll face two lefties in the earlier part of the week against the Reds (Nick Lodolo and Andrew Abbott).

• >Pirates (4 at PHI, 3 at WSH)

The Pirates project to face five right-handed starting pitchers in Week 15. Interestingly, the Pirates don’t have many strong-side platoon options of note.

• >Padres (3 at CHC, 4 at LAD)

There are four right-handed starting pitchers projected to face the Padres in Week 15. Max Muncy and Ryan Ward will take the biggest hit as strong-side platoon options. However, Muncy started against three of the six left-handed starting pitchers since June 1.

Shallow- and Medium-Size League Pickups (50% Rostered or Below)Mickey Moniak, OF, Rockies (38% Rostered)Mickey Moniak is back healthy. When the Rockies face right-handed starting pitchers, Moniak hits in the leadoff spot. The Rockies project to face six right-handed starting pitchers in Week 15. Moniak has a 143 wRC+ against right-handed pitchers. He crushes the ball in optimal launch angles, given his 8.4% barrel rate per plate appearance.

>Add and stream Moniak in most formats.

TJ Rumfield, 1B, Rockies (45% Rostered)Since June 1, TJ Rumfield has been productive at the plate. He has five home runs with a .318 batting average since June 1. Rumfield isn’t flashy with plenty of tools, but he makes contact 81.7% of the time while pulling the ball into the air 23% of the time. Listed at 6-foot-5 and 238 pounds, one might expect Rumfield to have more power than his 4.6% barrel rate per plate appearance.

>Like Moniak, we’ll want to be adding and streaming Rockies hitters in our lineups this week.

Dominic Canzone, OF, Mariners (17% Rostered)Luke Raley, 1B/OF, Mariners (14% Rostered)The Mariners project to face all right-handed starting pitchers for six games in Week 15. That benefits Dominic Canzone and Luke Raley. It’s a small sample, but Canzone has been hitting well since June 1. Canzone has five home runs with a .318 batting average since the beginning of June. On the season, Canzone rocks an 10.7% barrel rate per plate appearance, the best of his career.

>Meanwhile, Raley has been cold since June 1. Raley has one home run with a .125 batting average. The last time we recommended Raley as a volatile hitter who faces plenty of righties, he hit a couple of home runs. Raley could be a desperation option for streaming power in Week 15.

>They’ll face the Angels and Blue Jays, who have below-average to mediocre pitching staffs. Monitor Canzone (hamstring) and Raley (elbow), who each sat out of the game on Sunday. If Canzone and Raley miss Monday’s game, we’ll want to avoid any other Mariners’ bench options unless Victor Robles catches your eye.

Cole Young, 2B, Mariners (10% Rostered)Cole Young has three home runs and a .273 batting average in June. He has been slightly more productive this season, which can be partly explained by being more aggressive at the plate. Young is making more contact (82.3%) by swinging more often (47.1%), which is three points higher than in 2025. That comes with Young chasing 30% of the time, nearly seven points above his 2025 chase rate.

>Young pulls the ball into the air often (23.3%), with all of his seven home runs coming down the right field line. He is borderline in the deep-league waiver pickup and stream category for Week 15.

Cole Carrigg, OF, Rockies (14% Rostered)We have a theme here in Week 15 to target lower-rostered Rockies and Mariners hitters that play regularly. Cole Carrigg was recommended in last week’s article. Carrigg has been regularly playing center field for the Rockies since he was called up. He was known for speed as a prospect, which has been evident in his 93rd percentile Sprint Speed and 30 stolen bases at Triple-A this season.

>Carrigg is showing decent power skills, with a 74.4 mph bat speed and a 4.3% barrel rate per plate appearance in the early sample. There’s potentially league-average power in Carrigg’s bat. Plenty of Rockies and Mariners to add and stream in Week 15. Carrigg should be a priority in medium to deep leagues.

Henry Bolte, OF, Athletics (15% Rostered)In the latter half of the week, Henry Bolte was hitting in the leadoff spot. That makes sense because Bolte has an OBP north of .385, though it’s fueled by his .427 BABIP. With Bolte’s elite speed (100th percentile Sprint Speed), he rocks a 28% stolen base opportunity rate. Hitters with elite speed can run higher BABIPs.

>Bolte swings the bat hard (76.9 mph), but struggles with barreling the ball (3.8% barrel rate per plate appearance). That’s primarily because Bolte has a 65.9% groundball rate and poor plate discipline (67.5% contact rate). The Athletics play all six games at home this week, potentially leading to plenty of runs.

>Ride the BABIP, batting average and speed for Bolte in medium-to-deep formats.

Deep-League Hitter Pickups (10% Rostered or Below)Heriberto Hernández, OF, Marlins (2% Rostered)The Marlins play four games at the Rockies and three games at the Athletics. Sign us up for seven games in hitter-friendly environments. Most of the main Marlins’ hitters are rostered over the 50% mark. Caissie has intriguing power tools, but they project to face four right-handed starting pitchers in Week 15. The only low-rostered player who plays regularly is Heriberto Hernández.

>Hernández has hit six home runs with a .239 batting average since June 1. He struggles to make contact (68.7%) but hits the ball, with a 6% barrel rate per plate appearance. Hernández pulls the ball in the air 23.8% of the time, showing he sells out for power, pulling the ball 50.4% of the time. Don’t sleep on Hernández in deeper leagues against hitter-friendly matchups in Week 15.

Lars Nootbaar, OF, Cardinals (6% Rostered)The Cardinals project to face four left-handed starting pitchers in Week 15. After sitting against lefties in his first three games of the season since returning from the injured list, Nootbaar started against two southpaws recently and his .360 BABIP is fueling his high .294 batting average. He continues to barrel up the ball, with a 7.4% barrel rate per plate appearance this season. Nootbaar has been an asset in OBP and points leagues, so he should be a deep-league priority there.

Max Muncy, 2B/3B/SS, Athletics (7% Rostered)The Athletics face four right-handed starting pitchers in Week 15, all of which will be at home. For a while, Max Muncy projected as a strong-side platoon option. However, Muncy started against all eight left-handed starters since returning from the injured list on June 8. Muncy has been consistently hitting the ball into the air (19.1%) while continuing to barrel up the ball (6.9% barrel rate per plate appearance).

>It’s a mixed bag of matchups, including Eric Lauer, Justin Wrobleski and Shohei Ohtani in the first half of the week. Then the Athletics face Sandy Alcantara, Tyler Phillips and Euy Pérez in the latter half of the week. Look to stream Muncy in deeper leagues.
