Reds at Diamondbacks

O/U 8.5 · RL Diamondbacks -1.5 · Chase Field

GARY'S PICK

MLBvs Reds· -142

Friday night at Chase Field, the roof is closed and two left-handers take the ball as Cincinnati opens a long road trip against an Arizona club fighting to stay in the wild-card race. My money is on the Diamondbacks to win the game outright. Eduardo Rodriguez is the foundation of the bet. He brings a 2.71 ERA and 1.21 WHIP into a matchup with Nick Lodolo, who sits at 4.52 and 1.42. Both lineups start six right-handed hitters and two switch-hitters, making the pitchers’ work against righties especially relevant: Rodriguez has held them to a .233 average and .693 OPS, while Lodolo has allowed a .257 average and .808 OPS. Arizona also owns the stronger season-long production against left-handed pitching, batting .274 with a .785 OPS, compared with Cincinnati’s .239 and .740. Lodolo can absolutely give the Reds five competitive innings—he just threw five scoreless against Miami—but his two starts since returning from the injured list have ended after four and five frames. Rodriguez has completed at least six innings in four of his last five starts. That potential difference in starter length leads directly to Arizona’s other advantages. The Diamondbacks’ current bullpen carries a 3.23 ERA and 1.08 WHIP, against a 3.82 ERA and 1.27 WHIP for Cincinnati. Arizona has also committed 48 errors this season and four over its last seven games; the Reds have committed 71 and eight. Cincinnati arrives after playing seven consecutive days, while Arizona had Thursday off. I want the moneyline because the evidence says Arizona has the better route through nine innings, but it does not demand a multi-run result: all five meetings this season were decided by one run. At -142, I’ll pay for Rodriguez, the deeper bullpen and the cleaner defense without asking the Diamondbacks to cover the extra run.

The read

Eduardo Rodriguez is the foundation of the bet. He brings a 2.71 ERA and 1.21 WHIP into a matchup with Nick Lodolo, who sits at 4.52 and 1.42. Both lineups start six right-handed hitters and two switch-hitters, making the pitchers’ work against righties especially relevant: Rodriguez has held them to a .233 average and .693 OPS, while Lodolo has allowed a .257 average and .808 OPS. Arizona also owns the stronger season-long production against left-handed pitching, batting .274 with a .785 OPS, compared with Cincinnati’s .239 and .740. Lodolo can absolutely give the Reds five competitive innings—he just threw five scoreless against Miami—but his two starts since returning from the injured list have ended after four and five frames. Rodriguez has completed at least six innings in four of his last five starts.

That potential difference in starter length leads directly to Arizona’s other advantages. The Diamondbacks’ current bullpen carries a 3.23 ERA and 1.08 WHIP, against a 3.82 ERA and 1.27 WHIP for Cincinnati. Arizona has also committed 48 errors this season and four over its last seven games; the Reds have committed 71 and eight.

At -142, I’ll pay for Rodriguez, the deeper bullpen and the cleaner defense without asking the Diamondbacks to cover the extra run.

The research

The dated measurements the app shows under this card — observations with their sample and source, not predictions.

COOLING OFF

Elly De La Cruz: .514 OPS in Last 15 Days
.514
De La Cruz has cooled to a .514 OPS over his last 15 days, and it looks more like timing than luck. Arizona's a good spot for him to control the zone instead of trying to end the slump in one swing.

SITUATIONAL

CIN has played 10 days running — ARI rested yesterday
B2B+
Eleven straight game days for Cincinnati walking into a rested Arizona team is about as clean a fatigue edge as the board offers tonight. Give me the D-backs off that alone.

TEAM RECORD

Diamondbacks 6-1 in Eduardo Rodriguez's last 7 starts
6-1
Arizona is 6-1 in Eduardo Rodriguez's last seven starts, strong team support behind him all year. I like the Diamondbacks again tonight against Cincinnati.

REGRESSION

Eduardo Rodriguez: 2.71 ERA vs 4.72 xERA
4.72
Rodriguez's 2.71 ERA is running well ahead of a 4.72 expected mark — opponents hitting .238 against him when the underlying numbers say .266. Lines built off his season ERA might be underselling how hittable he's actually been tonight against Cincinnati.
Nick Lodolo: 4.52 ERA vs 5.98 xERA
5.98
Lodolo's 4.52 ERA is running well ahead of a 5.98 expected mark, with opponents hitting .271 against him versus an expected .287. He's gotten away with more than the contact quality suggests, so I'd be careful trusting him blind against Arizona tonight.

CLOSER WATCH

Brandyn Garcia / Dennis Santana
4 SV
Shared ninth in ARI: Brandyn Garcia 4 saves, Dennis Santana 2. The role is live.

FANTASY PICKUPS

Corbin Carroll
.830 OPS
An .830 OPS hitting in the 2-hole means volume — more trips to the plate than anyone else on this list. He faces Nick Lodolo tonight, and a 5.98 xERA from the opposing arm is about as soft a matchup as you'll find on a slate. The .246 average is the only blemish on an otherwise strong spot. Add him in standard mixed leagues — the matchup and the lineup spot both point the same direction.
Nolan Arenado
.765 OPS
The line is modest — .765 OPS, .243 average, batting 5th — but he's got the same green light as the rest of this group tonight: a struggling Nick Lodolo on the mound with a 5.98 xERA. I'm fading the average line and playing the matchup. One-day matchup streamer — usable in mixed leagues tonight, nothing more.
Geraldo Perdomo
.726 OPS
Lowest OPS of the three hitters I've got facing Lodolo tonight at .726, average sitting at .244, but he's batting cleanup in the 4-hole and gets the same 5.98-xERA, struggling arm that makes this matchup worth a look. Streamable in deeper mixed leagues or for SS-needy rosters — last priority of this group.

CUT LIST

Nick Lodolo
5.98 xERA
Starts tonight for CIN — 5.98 xERA behind a 4.52 ERA — the ERA is flattering him.

GARY'S PICK
GABRIEL MORENOTOTAL BASES OVER 1.5
MLBArizona Diamondbacks· +112
✓ CASHED · ACTUAL 2
I’m backing Moreno to clear 1.5 total bases at plus money. He is batting .370 with a 1.080 OPS over the last 15 days and has beaten this number in 11 of his last 15 games. The quality behind that run is convincing: a 91.0 mph average exit velocity, 10 hard-hit balls and three barrels on his last 21 balls in play. Nick Lodolo has allowed an .808 OPS to right-handed hitters, and his most-used pitch, the sinker, carries a .456 xwOBA and .312 batting average against it. Moreno bats third and has the extra-base ability to finish this with one swing. At +112, the matchup and current contact quality give me enough value to play the over.

GARY'S PICK
NICK LODOLOPITCHER OUTS UNDER 15.5
MLBCincinnati Reds· -158
✓ CASHED · ACTUAL 10
Lodolo needs to record an out in the sixth inning to beat this number, and Cincinnati has stopped him after four and five innings in his two starts since he returned. He threw only 70 and 73 pitches in those outings and has gone over 15.5 outs in just two of his last eight starts. Arizona presents eight hitters who will bat right-handed against him and owns a .274 average with a .785 OPS against left-handed pitching. Lodolo’s sinker has been hit hard, his season WHIP is 1.42, and Arizona can make him work even without producing a crooked number. The price is substantial, but five innings or fewer remains the clearest expectation.

SAL STEWARTHR OVER 0.5
MLBCincinnati Reds· +475
LOST · ACTUAL 0
Stewart leads every hitter on this field with 27 home runs, and he's not slowing down — three more in his last 15 games with a .791 OPS in that stretch. He's a right-handed hitter with a .898 OPS against lefties this season, and Eduardo Rodriguez is a lefty who's been far more hittable for power against righties than lefties this year — 11 homers allowed to right-handed bats compared to just 3 to lefties. That's Stewart's exact profile lining up with Rodriguez's exact weakness. The price undersells how live this bat has been all season.

LOST · ACTUAL 0
McLain is as hot as anyone in this lineup — he hit a grand slam last night and has three home runs in his last 15 games with an .845 OPS in that stretch. He's a right-handed bat who's done real damage against left-handed pitching, four homers in 74 at-bats this year, and his recent contact data backs it up: three barreled balls in his last 18 in play, the best rate on this board. Eduardo Rodriguez has had his own bumps lately too, a 4.34 ERA over his last three starts. At nearly 9-to-1, this price pays for itself if McLain keeps swinging the way he has been.

Suarez has hit for a .977 OPS with four home runs over his last 15 games, and this is a hitter built entirely around the long ball — 18 homers on the year, at almost the identical rate against both righties and lefties. He's 3-for-11 against Arizona pitching already this season. Eduardo Rodriguez is a good pitcher having a good year, but he's been worse than his season line over his last three starts, and Suarez doesn't need much of a mistake to leave the yard.

His sinker in particular has gotten hit hard all year. Arenado is a veteran who doesn't miss mistakes, and Lodolo has a history of leaving them out over the plate against right-handed bats.

ELLY DE LA CRUZHR OVER 0.5
MLBCincinnati Reds· +575
LOST · ACTUAL 0
De La Cruz's batting average has cratered the last two weeks — .143 over his last 15 games — but the contact quality hasn't: he's averaging 97.6 mph off the bat recently with a hard-hit rate near 65 percent, and he's still found the seats twice in that stretch. The bigger signal is what he does against left-handed pitching specifically: a 1.040 OPS with eight home runs in 115 at-bats this season, one of the biggest platoon splits on this roster. Eduardo Rodriguez is a quality lefty, but De La Cruz has made a habit of punishing pitchers who throw from that side, and the exit velocity says the swing is still there even while the average lags behind.
