The Cleveland Guardians have been impressive in 2024, leading the NL Central with a 35-17 record. Their success has come with the help of some unexpected reinforcements. Those players have become key fantasy baseball waiver wire pickups entering Week 10.

But the Guardians aren't the only team rostering fantasy baseball value. Through the ebbs and flows or a MLB season, players and teams find themselves in varying situations. Whether winning or losing, fantasy baseball players must be aware.

Once a player gains a new opportunity, whether via injury or ineffective play, the waiver wire must be checked. Adding a player with draft day value off waivers can be the difference between winning a championship or not.

Week 10 is no different. With the Guardians leading the way, these four players are must-add additions off of the fantasy baseball waiver wires. There's no telling when a hot streak might end, meaning being the first in your league to catch a trend will be crucial.

Every player on this last has 30 percent or less ownership in all ESPN fantasy baseball leagues.

David Fry, C/1B – Cleveland Guardians

There may not be a hitter hotter in baseball than Guardians catcher/first baseman David Fry. Over his last 13 games, Fry is hitting .435 with five home runs, 11 RBI and two stolen bases. He even has a position 11/9 BB/K ratio.

Due to his hot streak, Cleveland has moved Fry up to fourth or fifth in the lineup on most nights. He is now hitting .360 with six home runs, 19 RBI and three stolen bases on the season. On top of all of his stats, having eligibility at both catcher and first base only boosts Fry's value.

Finding value in fantasy baseball is hard, especially off of the waiver wire. But with Fry, things are made easy. There is no telling how long his hot streak might go. But as long as he is swinging the bat the way he is, he shouldn't be readily available off of waiver wires. Week 10 might be the last week to add Fry.

Ben Lively, SP, Guardians

For as good as Fry has been, he isn't the only Guardian looking to be an intriguing waiver wire pick up. Ben Lively has quietly put up a strong season and looks to hold long-term fantasy baseball potential.

Over his seven starts in Cleveland, Lively holds a 3-2 record with a 2.84 ERA and a 38/12 K/BB ratio. In his most recent start against the New York Mets, Lively pitched 5.2 innings of one run baseball, striking out seven while walking just one.

Lively has yet to allow more than three runs in any of his starts in 2024. In six of his seven appearances, the right-hander has five or more strikeouts. At 32-years-old, and away from MLB from 2019-2023, not many expected a resurgence from Lively.

But much like Fry, fantasy baseball owners must act quickly. While Lively's consistency points to continue success throughout the campaign, there isn't much of a long-term track record. Adding him in Week 10 ensures you get past the speculation have Lively on your roster coming off arguably his best start of the season.

Luis Matos, OF, San Francisco Giants

Ranked as the No. 7 prospect in the Giants organization by MLB Pipeline in 2023, Luis Matos got his second chance at the major leagues by getting called up on May 12. Ever since, all the outfielder has done is prove why he deserves to stay in San Francisco.

Over 13 games, Matos is hitting .278 with two home runs and 19 RBI. He matched the amount of home runs and is only five RBI from his 2023 totals during his first 31 MLB games. Aiding Matos' development is his rise up the lineup. He has served as San Francisco's leadoff hitter his past five games.

It has led to three runs scored and an overall opportunity improvement. When the Giants have a strong offensive day, Matos will be in the middle of it. He has given no reason for San Fran to remove him from his position.

For fantasy baseball players, that is waiver wire gold. It isn't often you can grab a former top prospect hitting leadoff for a team with playoff hopes. But that's exactly what Matos is offering entering Week 10.

Danny Jansen, C, Toronto Blue Jays

Danny Jansen began the season on the injured list after fracturing his wrist in March. But now back fully healthy, the backstop is proving to be one of the best hitters on the Blue Jays. At a weak position in fantasy baseball, Jansen could be a sneaky waiver wire option to fill the catcher spot on your roster.

Over the 26 games since his return, Jansen is hitting .309 with five home runs and 13 RBI. He has a sparkling 1.004 OPS. Jansen has gotten the added benefit of moving up in the lineup with him now occupying the No. 2 spot.

While Toronto has struggled to stay afloat in the competitive AL East, they still have plenty of stars in their lineup. Surrounded by the likes of Vladimir Guerrero Jr. and Bo Bichette, Jansen only gets a boost for hitting higher in the lineup.

Perhaps a forgotten man due to his offseason injury, Jansen is now proving to be a formidable force for the Blue Jays. If you're struggling for production at catcher, Toronto's backstop makes for a strong waiver wire addition entering Week 10.
