Giants vs Marlins SGP: San Francisco stays hot

The San Francisco Giants are rolling along an 8-5 stretch while averaging 5.6 runs per game and ranking fourth in wOBA and ninth in xwOBA.

In the opposite dugout, the Miami Marlins rank below average in both metrics during the same timeframe and are expected to piece together a bullpen game on Friday.

San Francisco, on the other hand, has sneaky righty Landen Roupp set to toe the rubber. He ranks in the 93rd percentile in hard-hit rate, with his 3.37 xERA and 3.44 xFIP both top-20 marks among qualified starters.

Still, because he’s only fanned six or more batters in one of his past five starts, the Under on his strikeout prop is a nice odds booster.

Finally, Giants outfielder Jung Hoo Lee sports an elite .325 batting average, and his 42.4% squared-up contact rate ranks seventh among qualified hitters.

I recommend backing this SGP down to +350.

Cardinals vs Royals SGP: McGreevy paves way to victory

St. Louis Cardinals righty Michael McGreevy has surrendered two runs or fewer in 10 of 14 starts this season while ranking in the 93rd percentile of fastball run value and 96th percentile in offspeed run value.

He’ll likely face the Kansas City Royals without superstar Bobby Witt Jr. (knee).

The Cards are rolling at the dish with a top-ranked xwOBA while averaging 5.8 runs per game the past two weeks. Additionally, this serves as a bounce-back spot for go-to hitter Ivan Herrera.

He’s mired in a 1-for-16 slump across the past five games after posting a sterling .371 wOBA and .372 xwOBA to start the season.

Finally, I anticipate the Royals will be off-balance against McGreevy without Witt anchoring their offense.

Because the shortstop paces the majors in WAR, his absence makes this SGP an advised play down to +300.

Orioles vs Dodgers SGP: Gibson struggles in L.A.

Los Angeles Dodgers righty Roki Sasaki sports a tidy 3.26 ERA at home, supported by an equally impressive 3.41 xFIP.

The Baltimore Orioles, on the flip side, haven’t traveled well with a 22nd-ranked road wOBA

Sasaki has also allowed just five hits across his past two home starts, and he’s surrendered four or fewer in four of his past five.

Turning to Baltimore rookie Trey Gibson, he brings a lackluster 6.62 xERA and 5.19 xFIP to the mound against a lineup pacing the majors in xwOBA across the past 30 days, so this SGP is in play down to +300.

Finally, Dodgers third baseman Max Muncy hits in the heart of the potent lineup and has posted an impressive .387 wOBA, .906 OPS, and .252 ISO against right-handed pitchers over the past three years.
