Best player prop bets for Monday’s MLB slate: Chapman to rough up Keuchel again

We are getting the week in Major League Baseball started with a 10-game slate on Monday, which includes an ESPN-televised showdown between the Oakland Athletics and Chicago White Sox. In other action, the New York Mets and San Francisco Giants are set for a crucial series between playoff contenders and an all-National League West tilt pits the San Diego Padres against the Colorado Rockies. Two of those games appear to be offering some nice value om player props.

Let’s take a look at our two best prop bets for Monday’s action, one on the pitching side of things and the other one at the plate.

Antonio Senzatela over 3.5 strikeouts (-122)

You have to wonder how Senzatela’s strikeout quota on Monday is only 3.5. The Rockies right-hander has reached the 4-strikeout mark in 7 of his last 8 starts, so it stands to reason that he should hit it again when Colorado hosts San Diego. During this 8-start stretch, Senzatela has recorded at least 5 strikeouts on 5 occasions, including an 8K gem against the Miami Marlins plus 6 Ks at the Chicago Cubs’ expense earlier this month. In his previous outing against the Padres this season the 26-year-old struck out 4 batters, and that was in only 5.0 innings of work. He has logged at least 6.0 innings in 7 of his last 9 efforts heading into Monday. Meanwhile, the Padres have fanned at least 7 times in 5 of their last 6 games; 3 different players on the roster have struck out 102 times during the 2021 campaign.

Matt Chapman to get a hit (-160)

It’s hard to see how Chapman is only -160 to record at least one hit on Monday, when his Athletics visit Dallas Keuchel and the White Sox. Chapman has been absolutely on fire over the past 5 days, with 3 multi-hit performances. The only game during this stretch in which he has gone hitless came last Thursday, when he had only one official at-bat because he walked a ridiculous 5 times and scored 3 runs. Chapman has 5 hits in the last 2 contests, including 3 home runs. As if all of that isn’t enough, the 28-year-old third baseman has enjoyed plenty of success against Keuchel in the past. Chapman is 6-for-15 lifetime versus the veteran southpaw with two homers and two doubles. For a -160 play, this is as close to a lock as you can get.
