The read
Saturday afternoon under the closed roof at loanDepot park, Eury Pérez takes the ball with Miami trying to build on Friday’s walk-off, while Jake Irvin attempts to steady Washington in Game 2. The Marlins’ -180 moneyline is outside the permitted range, so I’m taking Miami -1.5 at +116. The price forces a decision about margin, and my read is that today’s starting-pitching separation can become scoreboard separation.
Pérez brings a 3.23 ERA and 1.11 WHIP against Irvin’s 5.80 ERA and 1.36 WHIP. Across their last three starts, Pérez has allowed four earned runs in 18 innings; Irvin has allowed 11 in 14⅔. Pérez has also posted a 2.90 ERA at home, compared with Irvin’s 4.60 ERA on the road. The pitch results reinforce that gap: Pérez’s four-seamer carries a .260 xwOBA, with his slider at .239 and sweeper at .220. Irvin’s four-seamer is at .445 and his sinker at .481. Miami does not need to manufacture a huge inning immediately; repeated exposure to those damage-prone pitches should provide scoring opportunities.
Yesterday’s 3-2 result is the warning attached to laying a run and a half, but today’s pitching arrangement changes the shape of the game. Miami has scored 4.0 runs per game over its last five, while Washington has scored 2.2. Washington’s relief options also carry meaningful recent work: Clayton Beeter threw 15 pitches Thursday and 28 Friday, Orlando Ribalta worked both days, and Will Dion threw 48 pitches Friday. Miami used five relievers Friday, but Cade Gibson threw 12 pitches and Calvin Faucher threw only two. My bet is that Miami establishes the lead behind Pérez and receives another opportunity to create distance once Irvin departs. At plus money, I trust the strongest measured edge in this matchup enough to demand the extra run.

3Jake IrvinOVER 2.5 Pitcher Earned Runs Pitcher Earned Runs-107
WActual 4
I’m attacking the weakest part of this pitching matchup. Irvin has allowed 11 earned runs across his last 14 2/3 innings and has gone over this number in five of his last eight starts. His 5.80 ERA is supported by a 43.8% hard-hit rate and 12.3% barrel rate.
The pitch-level matchup is especially concerning. Irvin’s four-seamer and sinker combine for nearly half his usage while carrying .445 and .481 xwOBA marks. Miami has Griffin Conine, Owen Caissie and several strong contact hitters positioned to see those pitches repeatedly. At nearly even money, I’m betting the Marlins produce at least three earned runs before Irvin’s afternoon is finished.
Eury PerezUNDER 1.5 Pitcher Earned Runs Pitcher Earned Runs+105
WActual 1
Pérez has allowed one earned run or fewer in four of his last six starts, including consecutive scoreless outings covering 13 innings. Washington has averaged only 2.2 runs over its last five games, and today’s lineup is without CJ Abrams while also sitting Keibert Ruiz and Andrés Chaparro.
Pérez can attack this order without leaning on one pitch. His four-seamer, slider and sweeper have allowed xwOBA marks of .260 or lower, while the slider, sweeper and changeup all generate whiff rates above 40%. He has also held left-handed hitters to a .180 average and .560 OPS. Getting under 1.5 at plus money is the value point.
Griffin ConineOVER 0.5 Home Runs Home Runs+400
LActual 0
This is my long-price swing. Conine owns a 1.005 OPS with all 14 of his home runs coming in 142 at-bats against right-handed pitching. He has also hit four homers in 40 at-bats over the last 15 days, and batting second should give him multiple opportunities against Irvin.
Irvin has surrendered 12 home runs in 71 1/3 innings, with six of the 13 recent scoring plays against him coming on homers. His four-seamer has produced a .445 xwOBA and his sinker sits at .481. Conine’s swing-and-miss creates volatility, but +400 adequately pays for it in a matchup tailored to his left-handed power.
