Looking for the best fantasy baseball waiver wire pickups for Week 13? The waiver wire is buzzing with top prospects earning call-ups and young arms making waves. Whether you need steals, power, or pitching depth, here are the top names to target right now.
Top Fantasy Baseball Prospects for Week 13 Waver Wire
Chandler Simpson – OF – Tampa Bay Rays (16% rostered)
Chandler Simpson is back — and he could win you the stolen base category all by himself.
In his first MLB stint this season, Simpson swiped 19 bases and hit .285 in just 35 games. With Kameron Misner optioned to Triple-A, Simpson should return to the leadoff spot as the Rays head to Kansas City.
Expect elite steals, plenty of runs, and a solid batting average. If he’s still on your waiver wire, add him now.
Chase Burns – SP – Cincinnati Reds (46% rostered)
This is the moment fantasy managers have been waiting for: Chase Burns has arrived.
The No. 2 overall pick has rocketed from High-A to the majors in just 13 starts, posting a 12.1 K/9 and 1.8 BB/9. His fastball-slider combo dominated in two Triple-A outings (15 strikeouts).
Burns faces a tough Yankees lineup next — but he’s ready to contribute. Add him wherever he’s available.
Christian Moore – 2B – Los Angeles Angels (5% rostered)
Christian Moore joined the Angels on June 13 but is still adjusting to major league pitching. The 2024 No. 8 overall pick has yet to record a multi-hit game and has just one home run through his first 10 appearances.
He needs more time. Avoid him for now, but keep him on your radar in dynasty formats.
Didier Fuentes – SP – Atlanta Braves (4% rostered)
Didier Fuentes made his MLB debut last week, lasting five innings against the Marlins. The 20-year-old righty showed flashes of potential but struggled to put batters away.
Armed with a mid-90s fastball and limited Triple-A experience, Fuentes will need more seasoning. Avoid him for now, but monitor his next start — there’s streamer potential as he adjusts to big-league hitters.
Otto Kemp – 1B, 2B, 3B – Philadelphia Phillies (3% rostered)
Otto Kemp brings multi-position eligibility and intriguing power/speed upside. After hitting 14 home runs and stealing 11 bases at Triple-A this season, Kemp is batting .260 through his first 14 MLB games.
The power hasn’t surfaced yet, and he’s just 1-for-3 on stolen base attempts. Keep him on your watch list — if his bat heats up, he could quickly become a valuable add.
Jacob Misiorowski – SP, RP – Milwaukee Brewers (75% rostered)
Jacob Misiorowski is looking every bit like the budding ace fantasy managers hoped for.
Armed with a 99 mph fastball and filthy secondary pitches, Misiorowski has allowed just two earned runs while striking out 11 over his first two MLB starts. He dominated the Cardinals and tossed six scoreless innings against Minnesota before surrendering a seventh-inning homer.
If he’s somehow still available, add him immediately — or consider trading for him if you need starting pitching depth.
Jac Caglianone – 1B, OF – Kansas City Royals (50% rostered)
Jac Caglianone was one of the hottest names on prospect lists when he debuted with the Royals on June 3. After a slow start, the talented slugger is beginning to settle in.
Caglianone homered twice against the Rangers on Thursday and has quietly raised his batting average over the past few weeks. His 19.1% strikeout rate and impressive 47.1% hard-hit rate suggest a breakout could be coming soon.
This is your chance to capitalize on any impatient managers who gave up too quickly. If he’s available, grab him now.
Roman Anthony – OF – Boston Red Sox (54% rostered)
Roman Anthony was one of the most hyped prospects entering the season, but his early MLB results have been rocky. Since his June 9 call-up, Anthony has hit just .111 with one home run across 12 games, struggling to showcase the power/speed combo that made him a popular dynasty target.
However, there are signs of life — he’s scored in each of his last three games, suggesting the 21-year-old may be starting to adjust as the game slows down for him. If he can get rolling, a big second half could be on the horizon for Boston’s talented young outfielder.
