Blue Jays vs Orioles SGP: Yesavage Dominates O's

Toronto Blue Jays rookie Trey Yesavage has been impressive since returning from injury. Across six starts, he's compiled a 2.25 ERA, holding opponents to a .207 average. Yesavage has cashed the Under in earned runs allowed in all but one of his outings. He comes up against an inconsistent Baltimore Orioles lineup, and his ERA sits at 1.69 on the road. 

Toronto is riding a six-game winning streak against the Orioles, and three of those victories have been on the road. The O's have lost two straight at home. Ernie Clement has cashed the Over in runs in three of his last five games, and his high degree of contact (8.3% strikeout rate) leads to more opportunities to get on base and get driven in by Toronto's bats.

Padres vs Nationals SGP: Tatis Stays Hot

The San Diego Padres are riding a four-game winning streak on the road, and they've captured five victories in the last six meetings with the Washington Nationals. Washington has lost two straight, and starter Foster Griffin has allowed 14 earned runs across his last three starts. 

Michael King owns a 2.86 ERA on the road this season, and he's given up Under 2.5 earned runs in three of his last four contests. Fernando Tatis Jr. is finally starting to find a rhythm, with four multi-hit games over the last week. He's cashed the Over in total bases in back-to-back contests, and in four of his last five. 

Griffin is shaky at times lately, and Tatis is batting .317 against left-handers.

Diamondbacks vs Mariners SGP: Whiffs Against Woo

Bryan Woo has been inconsistent at times this season, but he's still missing a lot of bats. The right-hander has 59 Ks in 63.2 innings, and 34 in 31 frames at home.

Woo has cashed the Over in strikeouts in three of his last four appearances, and the Arizona Diamondbacks are striking out a lot more on the road, averaging 8.60 per game. Woo has a 70.7 first pitch strike percentage. He's getting ahead of hitters, which undoubtedly helps him strike out more opponents. 

The Seattle Mariners won the series opener by just one run on Friday, but they've now covered the run line in three of their last four contests. Ryne Nelson takes the hill for the D-Backs, who owns a 4.65 ERA. Julio Rodriguez is in the midst of a five-game hitting streak, and he had three hits on Friday.
