Top 3 Pitcher Prop Picks

1. Merrill Kelly 6+ Strikeouts in an Arizona Win (-145) Diamondbacks vs Rockies 9:10 p.m. ET

Merrill Kelly will be facing a Colorado team that leads the majors with a .476 slugging percentage in June on Saturday. However, the Rockies have struck out 163 times in 17 June games. Keep that in mind when it comes to making your MLB prop picks.

It is always a smart play for those who bet on MLB to tread carefully on the hits and runs allowed props at Coors Field, but the -145 odds for Kelly to have 6+ strikeouts in a win by the visiting Diamondbacks are worth considering.

The next win that RHP Merrill Kelly picks up will be his 60th in a #Dbacks uniform. Only two other pitchers have hit that milestone in club history (RJ, Webb).

RHP Zac Gallen is 77 strikeouts away from becoming the 3rd D’backs pitcher with 1,000+K in their ARZ career (RJ, Webb).

2. Dustin May 6+ Hits Allowed (+124) Dodgers vs Nationals 10:10 p.m. ET

Dustin May has a 5.29 ERA in June as he has allowed at least a hit per inning in each of his last three starts. Perhaps he will get healthy going up against a struggling Washington lineup that has been limited to three runs or less in 12 of 18 games in June. Before placing any MLB prop bets, remember that Washington hit three home runs, two coming off future Hall of Famer Clayton Kershaw, in the series-opening loss.

Dustin May did what he needed to do to keep the Dodgers in the game and give the offense time to get things headed in the right direction.

Avoid the MLB strikeout props since May has just four strikeouts in his last two starts. It might be worth considering the +124 odds for May to give up at least six hits to the Nationals.

3. Brandon Walter Over 4.5 Strikeouts (+100) Astros vs Angels 9:38 p.m. ET

The Angels d3o have 24 home runs in June. However, they are hitting .182 in the rest of their at-bats in the month, with a strikeout every 3.4 at-bats. They will be facing Brandon Walter, who is averaging a strikeout per inning in his three starts since being called up from the minor leagues. I like the -120 odds for Walter to go over 4.5 strikeouts against Mike Trout and the Angels on Saturday when making your MLB picks.
