Hot wire: 10 players to add in Yahoo fantasy leagues

Do you 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.
The following 10 players are sitting on waivers in many leagues and are ready to help your team in Yahoo Sports Fantasy Baseball, the Official Commissioner Game of MLB.
Nick Pivetta, starter, Phillies (46% owned)
Pivetta posted a promising 9.5 K/9 as a rookie last season, but he recorded a 6.02 ERA and a 1.51 WHIP, while struggling to limit walks (3.9 BB/9) and home runs (1.7 HR/9). He's drastically cut down on both this year, yielding just one home run and four walks through 28 innings, and the early returns have been impressive. It will be difficult for him to maintain 7.0 K/BB and 0.3 HR/9 all season, but his 2.57 ERA and 1.00 WHIP over his first five starts show how dominant the 25-year-old can be when he's on.
Matt Kemp, outfielder, Dodgers (43% owned)
Kemp has experienced a resurgence after returning to the Dodgers and shedding 40 pounds during the offseason, batting .317/.354/.533 through his first 20 games. While he hasn't approached that level of production since 2012, the 33-year-old still has a reasonably high floor after averaging 26 homers and 91 RBIs with a .780 OPS from 2015 through '17.

Tyson Ross, starter, Padres (38% owned)
After being limited to just 13 appearances (11 starts) in 2016 and '17 combined, Ross has looked like his old self after returning to San Diego on a Minor League deal during the offseason. The 31-year-old has gone at least six innings in all four of his starts while posting a 2.81 ERA, a 1.01 WHIP and a 24-to-7 K/BB ratio in 25 2/3 innings. Ross compiled a 3.07 ERA with a 3.13 FIP and a 9.2 K/9 with the Padres from '13-15, so he has an extended history of excelling in the Majors when healthy.

Michael A. Taylor, outfielder, Nationals (35% owned)
Taylor has been doing his best Billy Hamilton impression early this season, tallying nine stolen bases -- tops in the Majors -- without being caught. The steals should keep piling up for the 27-year-old speedster now that he has the green light from manager Dave Martinez to run at will. He hasn't provided much with the stick thus far, batting just .220/.289/.354 with two homers and a 33.3 percent strikeout rate, but he produced 19 homers with a .215 ISO over 399 at-bats as recently as last season.

Kurt Suzuki, catcher, Atlanta Braves (32% owned)
Suzuki enjoyed the best offensive season of his career last year at age 33, slashing .283/.351/.536 with a personal-best 19 homers in just 81 games. That success has carried over into 2018, as he's been one of baseball's best hitters at any position with a .327/.409/.600 batting line and four home runs in 18 games. He's also struck out just three times with six walks in 66 plate appearances. Suzuki will need to split playing time with Tyler Flowers once Flowers returns from the disabled list, but starting every day isn't a requirement for Suzuki to be a top 10 fantasy catcher.

David Dahl, outfielder, Rockies (29% owned)
With Carlos González (hamstring) on the disabled list and Gerardo Parra serving a four-game suspension until Friday, Dahl has gone 4-for-12 in their absence since being promoted on Sunday. The 24-year-old is capable of providing a short-term boost until CarGo and Parra return, having batted .315/.359/.500 with seven homers and five steals in 63 games as a rookie in 2016. It's unclear what Dahl's role will be when Gonzalez returns from the DL -- which could be by the end of the month -- but he's worth grabbing in deeper formats.

Max Kepler, outfielder, Twins (26% owned)
Kepler showed solid power during his first two full seasons, producing 36 home runs and a .185 ISO over '16-17, but his value was limited by a .239 average and a 89-to-207 BB/K ratio. The 25-year-old has shown better plate discipline thus far (8-to-7 BB/K ratio), which has helped him hit .283/.368/.583 with four home runs and six doubles in 18 games. If Kepler maintains his new approach, he could be headed for a breakout.

Walker Buehler, starter, Dodgers (24% owned)
MLB Pipeline's No. 12 prospect lived up to the hype in his first career start on Monday by twirling five shutout innings against the Marlins. Although the 23-year-old was optioned to the Minors on Tuesday, he's expected to be brought back up to face the Giants during Saturday's doubleheader. Although he struggled in relief as a September callup last year, Buehler is capable of making an immediate impact if he sticks around, based on his career 3.04 ERA and 12.4 K/9 rate in the Minor Leagues.

Vince Velasquez, starter, Phillies (21% owned)
Velasquez struggled with his command and consistency during his first three seasons, but he looks like a more polished pitcher this season. His 2.4 BB/9 is the best of his career, while his 10.4 K/9 matches his personal best from 2016. He's also done a better job of limiting mistakes after averaging 1.9 HR/9 last year, yielding just three home runs over his first 26 innings. Don't be fooled by his 1-3 record and 4.50 ERA, as his 3.17 FIP suggests the 25-year-old may be coming into his own.

Jason Heyward, outfielder, Cubs (7% owned)
Following a couple of down seasons to begin his Cubs tenure, Heyward is back to hitting like the player he was before. His .277/.360/.431 line is nearly identical to the .268/.353/.431 marks he put up before signing with the Cubs prior to the 2016 season. The 28-year-old is hitting more fly balls than ground balls for the first time in his career and has also been more selective, swinging at fewer than 25 percent of pitches outside the strike zone for the first time since 2010. This approach has yielded his highest hard-hit rate (36.2 percent) since his rookie season, indicating his rebound may be sustainable.
