Twins at Guardians: NRFI (-135)

Minnesota Twins left-hander Connor Prielipp has limited opposing batters to a .455 OPS while allowing just a pair of hits and a single run across seven opening innings.

Additionally, the Cleveland Guardians have overachieved at the dish of late, sporting a .336 wOBA (.310 xwOBA) across the past seven games.

I’m also expecting the Twins to struggle against emerging Cleveland star Parker Messick. He’s spun a tidy 2.40 ERA and 2.86 xERA while also pitching seven consecutive scoreless opening innings and allowing just two hits and a minuscule .247 OPS.

Nationals at Marlins: NRFI (-115)

Miami Marlins lefty Robby Snelling is set to make his MLB debut after posting a 1.86 ERA, 2.64 xFIP, and 40.0 K% across six Triple-A starts.

I’m fully anticipating Snelling to keep the Washington Nationals off balance in their first look at him, and the Nats also have the fifth-highest strikeout percentage against southpaws. 

Meanwhile, the Marlins are in tough against Washington LHP Foster Griffin. He’s held opposing hitters to a .442 OPS without allowing a single earned run through seven opening innings, and I also value him keeping batters to a 36.0% hard-hit rate.

Cardinals at Padres: NRFI (-115)

St. Louis Cardinals right-hander Michael McGreevy has pitched a scoreless first frame in six of seven starts and boasts a positive pitch value on each of his three most frequent offerings. This spells trouble for a San Diego Padres offense that has failed to score a run in the first inning in 83.8% of their games.

Similarly, the Cards rank middle of the pack in games without a first-inning run (70.3%) and now face Friars righty Griffin Canning following a solid season debut.

Canning scattered six baserunners across five innings while allowing just one run and striking out seven in his last outing, which also included a scoreless opening frame.
