The Arizona Diamondbacks come into their June 17, 2025 matchup against the Toronto Blue Jays riding the momentum of a successful homestand, having won five of their last six games to improve to 36–35 and stay within striking distance of a National League wild card spot. This stretch of solid play has been critical for a team that has struggled to maintain consistency on the road, where they’ve faced challenges both offensively and on the mound. The Diamondbacks will turn to right-hander Brandon Pfaadt for this second game of the series, and while his 8–4 record may suggest reliability, his 5.50 ERA tells a more complicated story marked by inconsistent command and occasional trouble keeping the ball in the yard. Tuesday marks Pfaadt’s first career appearance against the Blue Jays, and he’ll be tasked with navigating one of the American League’s more complete lineups in a hitter-friendly environment at Rogers Centre. The key for Arizona will be Pfaadt establishing his secondary pitches early and avoiding the kind of high-pitch innings that have derailed some of his earlier starts. Offensively, Arizona leans heavily on the dynamic Corbin Carroll, who leads the team in home runs (13) and RBIs (40) while providing speed and on-base ability at the top of the lineup.

Complementing Carroll is Geraldo Perdomo, who has quietly been one of the team’s most consistent hitters with a .293 average and reliable contact approach that helps set the table for run-scoring opportunities. However, outside of those two, the Diamondbacks have lacked sustained contributions from the rest of the order, especially when playing away from home, which has placed additional pressure on the top half of the lineup to produce. Arizona’s bullpen has been an area of concern throughout the season, as they’ve struggled to protect leads in close games, and the unit will be under scrutiny again, especially if Pfaadt can’t go deep into the game. Defensively, the Diamondbacks have held their own with solid infield play and good outfield range, though lapses in concentration have occasionally allowed extra opportunities for opponents to capitalize. Against a Toronto team with one of the best ATS records in baseball (36–23) and an offense capable of putting up crooked numbers quickly, Arizona’s margin for error is slim. From a betting perspective, the Diamondbacks’ 30–32 ATS record reflects their inconsistent play and difficulty staying within close margins when their pitching falters. To have a shot at pulling off the upset, Arizona needs Pfaadt to keep the ball in the yard, Carroll to spark the offense early, and the bullpen to hold its nerve in late-inning scenarios—none of which have been guaranteed outcomes this season. That said, if the Diamondbacks can continue to ride the momentum from their recent homestand and get timely contributions from up and down the lineup, they have the pieces to challenge Toronto and potentially steal a road win that could build confidence heading into the summer playoff race.
