Hot wire: 10 players to grab in Yahoo fantasy leagues

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.
Yonder Alonso, first baseman, Indians (45% owned)
Alonso struggled to begin the year after signing with the Indians during the offseason, batting .183/.258/.350 with a 21.2 percent strikeout rate through his first 17 games. He's starting to look pretty comfortable with his new team, however, powering five home runs and recording 12 RBIs over his past 11 games while batting .282/.310/.692 with a 14.3 percent strikeout rate. According to Statcast™, the slugger currently ranks 30th in the Majors (min. 50 at-bats) with an xwOBA of .415, which indicates he's been making strong contact. His ability to hit for power and get on base in Cleveland's potent lineup should yield positive results for fantasy owners.
Nick Kingham, starter, Pirates (41% owned)
Kingham flirted with baseball immortality in his MLB debut, taking a perfect game into the seventh inning vs. the Cardinals on Sunday and finishing with nine strikeouts. The dominant performance earned him another chance in Pittsburgh's rotation. Considering his track record of success on the farm (lifetime 3.37 ERA, 1.18 WHIP, 3.1 K/BB ratio), the 26-year-old may be ready to blossom at the Major League level.

C.J. Cron, first baseman, Rays (37% owned)
Although Cron has always had good power (career .191 ISO), his opportunities were limited with the Angels due to the presence of Albert Pujols and his own poor plate discipline. The slugger is still struggling with the latter in his first season with the Rays (3-to-29 BB/K ratio), but he's playing regularly and batting second with his new club. Furthermore, after belting 16 home runs every year from 2015-17, he's already gone deep seven times in '18. Cron averaged 24 homers and 85 RBIs per 162 games with Los Angeles, so there's 30/100 potential here.
Fernando Romero, starter, Twins (33% owned)
Romero was promoted from Triple-A and will make his MLB debut Wednesday, shifting Phil Hughes to the bullpen. Ranked as Minnesota's No. 2 prospect and the No. 66 prospect in the game by MLB Pipeline, Romero rose steadily through the Minor Leagues while recording a 2.83 ERA, a 1.17 WHIP and a 3.1 K/BB ratio across all levels. The 23-year-old displayed good command by registering a 2.8 BB/9 rate and a 0.2 HR/9 rate while averaging 8.7 K/9 on the farm, indicating that he may be capable of having immediate success against Major League hitters.

Mark Trumbo, outfielder, Orioles (26% owned)
Trumbo made his season debut Tuesday after missing all of April with a quadriceps strain, going 0-for-4 against the Angels in his return from the DL. While the slugger may need some time to get his timing back, the injury shouldn't hamper his swing. Trumbo has been one of the game's top power threats since his first full season in 2011, tying Adam Jones and Mike Trout for the ninth-most home runs in baseball from '11-17 with 201. For owners in need of power, a healthy Trumbo can provide an immediate lift.
Jackie Bradley Jr., outfielder, Red Sox (25% owned)
Bradley has been a streaky hitter throughout his career, and so far he's produced a disappointing .194/.283/.301 batting line with two home runs and nine RBIs. But a closer look reveals that he's been hurt by a .225 BABIP that is 68 points below his career mark. Bradley owns a 0.4 BB/K ratio -- identical to his mark over '16-17 -- and a career-low 11 percent soft-contact rate, so he should see his production pick up.
Ryon Healy, 1B/3B, Mariners (17% owned)
After missing nearly three weeks with a sprained ankle, Healy didn't take long to get back up to speed over the weekend. He's hit safely in four of five games since returning from the DL while clubbing three home runs and a double. Now healthy, the 26-year-old projects to be an impact bat, even if he's unable to improve his career 0.17 BB/K ratio. He's also eligible at both first and third base, which is a bonus.

Denard Span, outfielder, Rays (11% owned)
Span isn't the flashiest fantasy option, but he provided double-digit home runs and steals in each of the past two seasons while hitting .268/.330/.402 over both years combined. With three homers, two steals, 21 RBIs and a .266/.379/.456 batting line thus far, the 34-year-old remains a productive all-around contributor. He's also shown improved plate discipline (14-to-15 BB/K ratio), which should help him maintain a strong on-base percentage from the leadoff spot in the Rays' lineup.
Caleb Smith, starter, Marlins (9% owned)
After closing out April with a pair of dominant outings, Smith seems to be finding his way in the big leagues. Against the Brewers and the Rockies -- two formidable lineups -- he allowed just four hits and two earned runs with 19 strikeouts and only one walk over 13 innings. His command appears to be improving after he issued 10 walks in 18 2/3 innings last year and 15 free passes through his first 15 2/3 frames of 2018. Having demonstrated elite swing-and-miss ability (career 11.2 K/9 rate), the 26-year-old southpaw could be headed for a breakout if he keeps his walks in check.

Albert Almora Jr., outfielder, Cubs (6% owned)
Almora has settled in as the Cubs' leadoff hitter over the past two weeks, which is an enviable place to be with so many big bats behind him. Manager Joe Maddon said he's committed to keeping Almora there for the time being. Almora has already scored 16 runs in 23 games, and he should continue reaching base at an above-average clip based on his career .292 average and .331 OBP.
