Outlook Sam Antonacci

Sam Antonacci's elite speed and secure role make him a prime fantasy target.

The rookie has cemented himself as the primary everyday left fielder for Chicago, batting .286 with three stolen bases over his last seven games. He has been a key spark plug for the second-place White Sox, who are riding a five-game winning streak. Antonacci's near-term playing time is highly secure given the team's extensive outfield injuries.

While his single career home run underscores his minimal power, his speed and run-scoring ability are completely legitimate. He has maintained an impressive .366 career on-base percentage by routinely putting the ball in play and using his aggressive style to get on base. Our models expect his high-contact approach to keep his average stable near his .275 career baseline.

Chicago has six road games scheduled this week against Minnesota and Philadelphia. While facing Joe Ryan is a tough draw, Antonacci will get to feast on high-ERA arms like Connor Prielipp, Andrew Painter, and Aaron Nola later in the week. Given these favorable matchups and his high stolen-base projection, he is a recommended option. Start.

Outlook Geraldo Perdomo

Perdomo Aims to Ignite Bat During Favorable Seven-Game Homestand

The third-place Diamondbacks are looking to snap a three-game slide with everyday shortstop Geraldo Perdomo leading the infield. Although Perdomo has battled a cold stretch, batting just .204 over his last 30 days, he has avoided the injured list following an early-season ankle sprain and remains locked into his starting role with backup shortstop Jordan Lawlar sidelined.

While his current .224 season average is disappointing, especially after last year’s career-best .290 mark with 20 home runs, our models suggest better days are ahead. Perdomo maintains his elite plate discipline, and his projected rest-of-season bounce-back toward a .268 batting average with double-digit power and speed makes him a prime candidate for positive regression.

This week, Arizona plays seven home games, starting with four against the Dodgers before hosting Washington. Perdomo faces several highly beatable arms like Eric Lauer (5.95 ERA) and Zack Littell (5.01 ERA), making this high-volume week an ideal environment to insert him back into lineups as a weekly Start.
