Week 21 fantasy baseball focuses on 2025 redraft value from a curated top-25 stash list. Prospect call-ups that debut this year preserve rookie eligibility for 2026, broadening short- and long-term value. Promoted last week: Dylan Beavers, Samuel Basallo, Drew Gilbert, Nolan McLean and Owen Caissie, with Eldridge and Sal Stewart standing out for immediate impact in power and solid hitting floors. The piece highlights Spencer Jones’s sky-high upside despite strikeout risk, JJ Wetherholt’s Triple-A dominance, and Robby Snelling’s near‑MLB-ready pitcher profile.

Analysis dives into Bryce Eldridge’s likely Giants cup of coffee, Sal Stewart’s advanced hit tool, and Wetherholt’s polished approach at the plate. It maps out why these names belong on rosters in 2025 redraft and how late-season call-ups could shape Week 21 lineups. Honorable mentions add depth across teams, while the feature ties in DFS and lineup tools to sharpen Week 21 decisions.

Brewers 7, Cubs 0 in a rain-soaked makeup at Wrigley. Chicago could muster only two hits and three walks while the pitching staff labored, with Cade Horton exiting early with a blister and the bullpen splintering after Luke Little’s sixth-inning appearance (even a pitch timer violation). Seiya Suzuki celebrated his 31st birthday with a patient at-bat, but Owen Caissie supplied the Cubs’ lone bright moment with his first big-league hit as Chicago failed to find offense in a lopsided day.

What looms now is a Tuesday doubleheader that could reshape the Cubs’ immediate plans. Jameson Taillon was listed to start the day game, with Jordan Wicks likely serving as the 27th man for the nightcap, while the weather forecast promises better conditions. The Brewers, meanwhile, used a steady attack and a weather-delayed rhythm to cruise to the win, leaving Chicago to reset during a pivotal late-season stretch.

Reds ended Milwaukee’s franchise-record 14-game win streak in extras, snapping a weekend of close games as Milwaukee’s lead in the NL Central remains fragile.

The Cubs seized a rare chance to gain ground, beating the Pirates 4-3 at Wrigley and pulling within eight games of the Brewers ahead of a pivotal five-game set in Chicago that begins with a doubleheader.

Dansby Swanson and Ian Happ spoke to Cubs’ DNA—defense, baserunning, and late-inning grit—even as the offense has slogged through August. Chicago used small-ball, an unearned run, and timely plays to claim the series win, with Swanson driving in the deciding run on a bases-loaded sac fly. Owen Caissie debuted as a pinch-hitter in the series’ final game, signaling deeper depth for the Cubs as they chase a breakthrough month.

Owen Caissie, 23, slid into Chicago’s lineup with a travel-day sprint and a big-league baptism at Rogers Centre, debuting as the designated hitter in the Cubs’ interleague set. He drew two walks and delivered an RBI double in his first major-league action, while facing Max Scherzer in his first at-bat and seeing a diving play from Davis Schneider deny an extra-base hit. Recalled from Triple-A Iowa after Miguel Amaya landed on the injured list, Caissie is positioned as a high-upside project with a long runway ahead.

The Cubs view him as a hitter with power and strong plate discipline, but Counsell stressed flexibility rather than a fixed role as the schedule evolves. Caissie’s season at Iowa (.289, 22 HR, 52 RBI) and a standout Futures Game performance suggest a ceiling that could push him into regular at-bats as rest days and matchups allow. The Yu Darvish trade that brought him to Chicago in 2020 hangs over the narrative, underscoring the franchise’s patience with a high-ceiling youngster who could become a cornerstone once he seizes the opportunity.

Vladimir Guerrero Jr. delivered the game’s decisive blow, a go-ahead two-run homer for Toronto, his 20th of the season, after a Davis Schneider leadoff walk set the stage. The left-center blast off an 0-2 curveball gave the Blue Jays a 2-1 edge and helped Jeff Hoffman lock down his 27th save in 32 chances as Toronto won the rubber game of the interleague series.

Max Scherzer outdueled Matthew Boyd, allowing one earned run over seven innings before being lifted in the eighth following Matt Shaw’s leadoff double. Brendon Little and Seranthony Domínguez finished the frame, with Domínguez striking out Carson Kelly with two runners in scoring position to preserve the slim lead.

Owen Caissie, a Burlington, Ontario native, was denied his first big-league hit when Davis Schneider tracked back for a highlight-reel diving catch. Caissie was recalled from Triple-A Iowa earlier in the day. Michael Busch supplied a Cubs solo homer, but Toronto’s bullpen extinguished the threat to seal a two-hour, six-minute afternoon at Rogers Centre.

With the win, the Blue Jays (71-51) sit atop the AL, while the Cubs (68-52) have dropped four of six. Toronto will continue its six-game homestand against Chicago in the finale of the interleague set.
