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 morning.
Mike Soroka, starter, Braves (43% owned)
Soroka shined in his MLB debut against the Mets on May 1, limiting New York to just one run over six innings while striking out five for his first career win. He wasn't as sharp in his second start on Sunday, yielding four runs on seven hits over four innings in a loss to the Giants, but the ups and downs are to be expected from the 20-year-old righty. The Braves' No. 3 prospect per MLB Pipeline offers considerable upside after compiling a 2.85 ERA with a 1.10 WHIP and a 4.1 K/BB ratio in the Minor Leagues, making him worth adding in most formats.
Kyle Gibson, starter, Twins (24% owned)
Coming off a strong second half last year in which he went 7-3 with a 3.76 ERA, a 1.28 WHIP and an 8.2 K/9 rate while honing his slider into an effective out pitch, Gibson has taken another step forward in 2018. Gibson has posted a career-high 10.2 K/9 rate over his first seven starts alongside a .207 batting average against, as he's yielded just 6.8 H/9 after averaging 9.7 H/9 from 2013-17. His 3.49 ERA and 1.22 WHIP are in line with last year's post-All-Star-break performance, and his 3.11 FIP and 3.73 xFIP suggest his hot start may be sustainable.

Jose Bautista, 3B/OF, Braves (18% owned)
Bautista made his season debut last Friday after signing with Atlanta on April 18, doubling in his first Braves plate appearance. The 37-year-old struggled in his final season with the Blue Jays last year, batting .203/.308/.366 with a career-high 170 strikeouts, but he still showed good power and patience with 23 home runs and a 12.2 percent walk rate. Bautista's batting eye remains intact based on his 13-to-12 BB/K ratio in 16 games across all levels this year, making him a worthy pickup in leagues that utilize on-base percentage.
Seunghwan Oh, reliever, Blue Jays (17% owned)
Toronto's closer situation is in flux after Roberto Osuna was placed on administrative leave Tuesday, and Oh is as strong a candidate to replace him as anyone in the Blue Jays' bullpen. The 35-year-old is flourishing in his first season with Toronto, notching a 1.76 ERA and a 1.11 WHIP with a 5.0 K/BB ratio in 15 1/3 innings. He's also tallied 40 saves since his first MLB season in 2016. Manager John Gibbons is considering using a closer committee, however, so John Axford, Dennis Tepera and even Tyler Clippard may be in the mix for saves as well.
Tyler Anderson, starter, Rockies (16% owned)
Anderson showed promise as a rookie in 2016 with a 3.54 ERA and a 3.59 FIP in 19 starts before taking a step back last year with a 4.81 ERA and a 4.67 FIP, as his HR/9 rate increased from 0.9 to 1.7. But the southpaw still made strides by improving his K/9 rate from 7.8 to 8.5, and he's bumped it again in 2018 (10.0 K/9). Although the 28-year-old owns a career-high 4.3 BB/9 rate with a 1.4 HR/9 rate this season and has the added challenge of making home starts at Coors Field, his improved strikeout skills should intrigue owners in deeper mixed leagues.

Kyle Freeland, starter, Rockies (11% owned)
While Freeland posted a serviceable 4.10 ERA in 156 innings as a rookie, his 4.57 FIP, 1.49 WHIP and 1.7 K/BB ratio were far from impressive. His peripherals are much improved this year, however, as he's increased his K/9 rate from 6.2 to 8.3 while trimming his BB/9 rate from 3.6 to 2.9 and dropping his hard-hit rate from 32 percent to 26.5 percent. As a result, the lefty has recorded a 3.95 ERA, a 3.84 FIP and a 1.17 WHIP over his first seven starts of 2018. The 2014 eighth overall Draft pick is worth grabbing to see if he can keep it up.
Zach Eflin, starter, Phillies (8% owned)
Eflin struggled to the tune of a 5.85 ERA and a 5.79 FIP in 2016 and 2017 combined, mainly because he allowed too much hard contact (2.0 HR/9) and didn't miss enough bats (4.7 K/9). But the 24-year-old has looked like a different pitcher since being recalled to replace the injured Ben Lively in Philadelphia's rotation, yielding just one earned run in 12 2/3 innings over his first two starts while recording 13 strikeouts. Jerad Eickhoff is expected to reclaim his rotation spot when he returns later in May, but Eflin could remain in the rotation if he continues his recent dominance.
Andrew Heaney, starter, Angels (6% owned)
After being limited to just six starts between 2016 and '17, Heaney is starting to resemble the pitcher he was before undergoing Tommy John surgery. Perhaps most importantly, he has yielded only three homers in 26 1/3 innings (1.0 HR/9 rate) this season after allowing 12 in 21 2/3 innings (5.0 HR/9 rate) upon returning to the mound last year. With a 2.12 ERA and a 1.18 WHIP over his past three starts, the 26-year-old southpaw is trending in the right direction and could be effective the rest of the way if he stays healthy.

Carson Kelly, catcher, Cardinals (4% owned)
With Yadier Molina likely out until June following groin surgery, Kelly will get another chance to prove himself behind the plate. He struggled during his previous callups in 2016 and 2017, hitting .171/.236/.220 with no home runs and seven RBIs in 89 plate appearances, but the 23-year-old could be ready to make an impact after slashing .283/.375/.459 at Triple-A Memphis last year. For Molina owners in need of a replacement, Kelly is worth taking a chance on.
Devin Mesoraco, catcher, Mets (1% owned)
Following Tuesday's trade to the Mets for Matt Harvey, Mesoraco is expected to slot in as New York's primary catcher with Travis d'Arnaud out for the season and Kevin Plawecki on the disabled list. Mesoraco appeared in just 95 games over the past three years combined, but in his last healthy season in 2014, he batted .273/.359/.534 with 25 home runs and 80 RBIs in only 384 at-bats. He's been healthy thus far in 2018, making him a potential rebound candidate now that he's guaranteed regular playing time.
