Los Angeles Angels at Pittsburgh Pirates Best Bets

Mitch Keller takes the mound for the Pirates and there should be some "progression" to the mean considering the slow start he's had. He's struck out seven batters in each of his last two starts and right now the Angels' lineup doesn't look that good considering their injuries (most notably Mike Trout). The Pirates have had success against southpaws this season (.325 wOBA, 12th in baseball) and Tyler Anderson had a 5.93 ERA on the road last season.

Seattle Mariners at Minnesota Twins Bets Bets

I'm a sucker for picking Luis Castillo when he starts and tonight will be no different. In a small sample he's actually been better on the road than at home this season and the Twins have not had a lot of success against him. Six of the projected batters in the lineup for Minnesota have gone 5-for-39 (.128) against Castillo, while Jose Miranda has never faced him (a matchup that typically favors the pitcher). Simeon Woods Richardson isn't considered a top prospect and he's struggled in the minors with a 4.91 ERA at Triple-A last season

Miami Marlins at Los Angeles Dodgers Best Bets

I'm going to ride the hot hand here and back Shohei Ohtani, who has a 1.536 OPS over the last week. He's hit three home runs in his last two games and has gone over 2.5 Hits+Runs+RBI in each of his last three games. Ohtani will face off against Roddery Munoz, who until reaching the big leagues was shelled at Triple-A with an 8.62 ERA in four starts (15.2 innings). Look for Ohtani to keep swinging a hot bat and hit this over.
