Shane McClanahan Under 1.5 earned runs (+109)

The Tampa Bay Rays are undoubtedly delighted to have their ace healthy and dominating. Shane McClanahan owns a 4-2 record and 2.27 ERA through eight starts, and he's on quite a run at the moment. The left-hander has tossed four straight scoreless outings

In fact, he's also given up just three hits across his last two appearances. McClanahan is at home tonight to face the Baltimore Orioles, and the southpaw owns a mind-boggling 0.87 ERA at Tropicana Field. Baltimore is also hitting just .125 against him across 25 at-bats.

Yoshinobu Yamamoto Over 6.5 strikeouts (-115)

Yoshinobu Yamamoto has been a strikeout pitcher ever since he stepped into the Majors, and 2026 is no different. The right-hander has nearly one K per inning, racking up 48 punchouts in 50 frames. Yamamoto has given up more runs than usual lately, but he's cashed the Over in strikeouts in three of his last four. 

The Japanese star has eight Ks in back-to-back appearances, and he's also hit the Over in two straight road outings as the Los Angeles Dodgers visit the San Diego Padres tonight.

He's also collected quite a few punchouts against several key Padres hitters, such as Manny Machado, Fernando Tatis Jr, and Xander Bogaerts. San Diego is 18th in strikeouts as well. 

Time: 9:40 p.m. ET

SportsNet LA, Padres.TV

Corbin Carroll Over 1.5 total bases (+120)

Corbin Carroll is one of the hottest hitters in the show, batting .421 over the last week, and the outfielder is coming off a two-homer performance on Sunday against the Rockies. Carroll has now cashed the Over in total bases in four consecutive games.

Just two of those were multi-hit games, but he's finding the gaps lately as well, smacking two doubles during that span. Carroll can also put his 96th-percentile sprint speed to good use, turning singles into doubles.

Carroll will face Robbie Ray of the San Francisco Giants tonight. Ray does have trouble with extra-base hits at times, most notably surrendering 10 homers
