Alek Manoah Under 5.5 Hits Allowed (-115 at BetMGM Sportsbook)

Despite a disappointing start to the 2023 season, Alek Manoah is favored for Monday night's game with the Toronto Blue Jays. While his stuff and command have been lacking compared to his breakout 2022 season, 

Manoah has a history of dominating the New York Yankees, with a 1.93 ERA over seven starts, including an impressive outing last month. Furthermore, the Yankees have struggled offensively on the road, providing Manoah with the opportunity to cruise through the game.

Brad Keller Under 3.5 Strikeouts (-104, FanDuel Sportsbook)

Brad Keller's low strikeout rate and recent control issues suggest he may struggle against the San Diego Padres lineup. Keller's season strikeout rate of 16.3% is in line with his career average, but his high 18% walk rate leads to a disastrous -1.7% K-BB% on the season. 

Facing a Padres offense with a 10.4% walk rate, Keller is unlikely to approach the 3.5 strikeouts total, particularly if his pitch count rises.

Freddy Peralta Over 17.5 Outs Recorded (-130 at DraftKings Sportsbook)

Freddy Peralta has an opportunity to shine against the struggling St. Louis Cardinals on Monday. With a strong performance, Peralta is likely to be allowed to complete at least six innings, recording more than 17.5 outs. 

Peralta has been in excellent form, recording at least 18 outs in five of his seven starts, including his last three. In addition, the Cardinals may be tired after playing a late game on Sunday. With Peralta's ability to stay out of trouble on the mound, he should be able to go deep into the game and help secure a victory for the Brewers.
