Athletics at Tigers (-185, O/U 7.5)

Why to bet on Athletics: Oakland has won the first three games of the series, outscoring Detroit 28-13. Bartolo Colon may break into a sweat when he bends over to tie his shoes, but he’s the A’s ace — even if he’s struggled in his last two starts.
Why to bet on Tigers: Max Scherzer. The righty is 19-1 on the season and has a 1.48 ERA in seven starts since the all-star break. You can also be sure Detroit doesn’t want to be swept in a four-game series at home.
Our pick: Over

Brewers at Pirates (-155, O/U 7.5)

Why to bet on Brewers: Yovani Gallardo has had the Pirates’ number at PNC Park, going 4-2 with a 1.69 ERA in seven career starts. Milwaukee has won 62 of its last 89 games against Pittsburgh.
Why to bet on Pirates: Starter Gerrit Cole is on seven days rest, and that’s a good thing. He is 4-0 with a 2.84 ERA in four starts this year after having six or more days rest between appearances.
Our pick: Pirates

Indians at Braves (-150, O/U 7.5)

Why to bet on Indians: Ubaldo Jimenez returns to Atlanta, where he no-hit the Braves while pitching for the Rockies in 2010.
Why to bet on Braves: This is more of a reason to bet against Cleveland, but the Indians are struggling at the plate, scoring three runs or less in five of their last six games.
Our pick: Under

Orioles at Red Sox (-160, O/U 9)

Why to bet on Orioles: Chris Tillman has dominated Boston in his last five starts, going 3-0 with a 0.84 ERA. In his last two appearances, he’s tossed 13 scoreless innings.
Why to bet on Red Sox: Ace lefty Jon Lester is rounding into form, allowing one run in his last 15 2/3 innings. Bosox are 47-23 in their last 70 games against Baltimore at Fenway.
Our pick: Orioles
