Angels at Guardians: NRFI (-110)

The Los Angeles Angels and Cleveland Guardians played to a scoreless first inning in the series opener, and a similar start offers great value today.

Walbert Urena takes the mound for the Angels and hasn’t allowed a first-inning run in four outings this season. Cleveland, meanwhile, has failed to score in the opening frame in three straight games.

For the Guardians, Slade Cecconi gets the start. Despite a 6.15 ERA, he delivered a clean first inning in his last outing and draws an Angels lineup that has struggled out of the gates, going scoreless in the first inning in five consecutive contests.

Nationals at Reds: YRFI (-130)

Tonight's pitching matchup between the Washington Nationals and Cincinnati Reds screams runs.

Miles Mikolas and Brady Singer both have poor ERAs, and Singer has struggled to come out of the first unscathed.

Singer owns a 3-5 NRFI/YRFI record, and the right-hander has given up a first-inning run in four straight appearances. The Nats are also hitting .315 in the first inning and have scored in the opening frame in two of their last three games.

Rays at Blue Jays: NRFI (-113)

It's an all-lefty matchup between the Toronto Blue Jays and Tampa Bay Rays tonight as Shane McClanahan toes the rubber opposite of Patrick Corbin.

McClanahan has allowed a run in the first just once this season, and he's tossed three scoreless first innings in a row. As for Corbin, the veteran southpaw boasts five straight scoreless innings. 

Both teams are also hitting around .230 in the opening frame. Corbin faced the Rays in his last outing and allowed just two runs, both coming in the fourth inning. McClanahan countered for Tampa in that matchup and blanked the Jays over 5 2/3 IP.
