Need an impact arm or bat that can give your fantasy team a boost? Whether you're looking for an injury replacement or someone to stash on your bench, the fantasy waiver wire has a plug or long-term fix to pick up today. Check out the following 10 players -- all sitting on waivers in many leagues, and all ready to help your team in Yahoo Sports Fantasy Baseball, the Official Commissioner Game of MLB. All statistics and ownership percentages are as of Wednesday.
Marcus Stroman, starter, Blue Jays (49% owned)
Stroman was sharp in his return from the disabled list on June 23, throwing five scoreless innings against the Angels. The 27-year-old scuffled with a 7.71 ERA and a 1.71 WHIP over his first seven starts before going on the DL with shoulder fatigue, but he should be able to put that slow start behind him now that he's healthy. Stroman went 37-25 with a 3.61 ERA and a 1.25 WHIP over his first four seasons from 2014-17, making him a must-add in most leagues.
Domingo German, starter/reliever, Yankees (37% owned)
German struggled in his last start (six earned runs in three innings), but has been trending in the right direction since moving from the bullpen to the rotation in early May. The 25-year-old rookie had gone at least six innings in his four previous outings, three of which qualified as quality starts. He's also demonstrated elite strikeout potential with a 10.5 K/9 rate this year while limiting his walks to 3.0 BB/9 . His 1.6 HR/9 rate has contributed to a 5.40 ERA thus far, but his 4.21 FIP and 1.23 WHIP suggest he'll have better luck preventing runs going forward.

Yan Gomes, catcher, Indians (36% owned)
After hitting just .215/.266/.377 from 2015-'17 while battling various injuries, Gomes is healthy and enjoying his best season since '14, when batted .278/.313/.472 with 21 homers and 74 RBIs en route to winning a Silver Slugger. Gomes has avoided the disabled list after averaging 91 games played over the past three years and has been productive at the plate, slashing .249/.315/.448 with nine homers and 24 RBIs in 56 games. If he stays on the field, he has the potential to reach 20 homers again while providing solid counting stats in Cleveland's potent lineup.
Sam Dyson, reliever, Giants (31% owned)
Dyson has re-emerged as a closing option for San Francisco with Hunter Strickland (hand) likely out until at least August. The righty acquitted himself well as the Giants' primary ninth-inning option in the second half last year, recording 14 saves with a 3.82 ERA from July 1 onward. Dyson is expected to split closing duties with Mark Melancon and Tony Watson, but he's already notched a pair of saves since Strickland went on the DL on June 19 and should continue to see save chances.
Manuel Margot, outfielder, Padres (31% owned)
Margot started the year slowly but has found his stride in June, slashing .333/.407/.542 with 10 extra-base hits in 22 games this month. While the 23-year-old sophomore is still developing, he displayed a nice blend of power and speed as a rookie last year with 13 homers and 17 steals in 126 games. His poor start caused him to be moved out of the leadoff spot, but he's batted first or second in each of San Diego's last three games and could see a boost in value if he continues hitting near the top of the lineup.

A.J. Minter, reliever, Braves (31% owned)
With Arodys Vizcaino (shoulder) on the disabled list until at least Sunday, Minter could see some save opportunities this week and is worth adding in leagues with daily transactions. The 24-year-old rookie has pitched well in a setup role this year, going 3-1 with 3.09 ERA, a 2.63 FIP and a 9.8 K/9 ratio in 32 innings. Vizcaino owners should consider stashing him in deeper leagues as an insurance policy in case Vizcaino's injury lingers or flares up again later in the season.
Kevin Kiermaier, outfielder, Rays (21% owned)
After missing more than two months with a torn thumb ligament, Kiermaier has started to come around since being activated from the disabled list on June 19. The speedy outfielder has hit safely in his last four games, notching a pair of steals and going deep for the first time this year with a grand slam on Monday. The 28-year-old exceeded double-digit home runs and steals every year from 2015-17, making him a worthwhile addition to fantasy rosters.
Gerardo Parra, outfielder, Rockies (21% owned)
After struggling in his first season with Colorado in 2016, Parra rebounded to bat .309/.341/.452 last year and is posting nearly identical numbers (.303/.340/.424) this year. He's also been a solid source of power and speed with five homers and six steals, putting him on pace to reach double digits in both categories for the first time since '15. The 31-year-old has a relatively high floor thanks to Coors Field, where he's a career .303/.338/.449 hitter.

Austin Romine, catcher, Yankees (20% owned)
With Gary Sanchez expected to miss three to four weeks after landing on the disabled list Monday, Romine will take over as New York's primary backstop. The 29-year-old is in the midst of his best season at the plate, batting .289/.350/.500 with four home runs, 20 RBIs and a 9-to-19 BB/K ratio in 30 games thus far. With a hitter-friendly home park and one of baseball's best offenses around him, Romine projects to be a strong fantasy option until Sanchez returns.
Tom Murphy, catcher, Rockies (8% owned)
Murphy has flourished since making his season debut on June 12, hitting safely in seven of his 10 games while batting .325/.341/.450 with six RBIs. His 1:16 BB/K ratio is cause for concern, but he was destroying Triple-A prior to his promotion, slashing .289/.359/.642 with 16 homers and 45 RBIs in 49 games this year. The 27-year-old has appeared in just 54 MLB games since debuting in 2015, but he appears ready to take over as Colorado's primary catcher and could post big numbers with the help of Coors Field.
