MLB Sharp Report: Royals-Tigers, A’s-White Sox Drawing Saturday’s Pro Money

Week 1 of the NFL preseason caps off tonight, but a 15-game MLB slate has still garnered plenty of attention Saturday, with a couple games in particular drawing action from sharp bettors.

Kansas City Royals vs. Detroit Tigers

6:10 p.m. ET

The Royals may be four games up on the Tigers in the AL Central, but at 1-9 in their last 10 they're having a hard time drawing bettors tonight in Detroit. Only 49% of bettors have taken the Royals, which raises interest on how this line has reacted.

After opening shorter than -120, Detroit is now up to around -134 across most of the market, and one shop is even posting a -140. Given the even betting percentages, it's pretty clear that sharps are probably among the 51% on the home side.

Sports Insights' Bet Signals confirm that professional action, as they've triggered a steam move on the Tigers at -127. Detroit's 51% backing has also accounted for 65% of actual money, meaning bigger bettors — the ones more likely to be sharps — are taking the favorite.

Oakland Athletics vs. Chicago White Sox

7:10 p.m. ET

A very similar story is taking place in tonight's A's-White Sox matchup. This one, however, is on the total.

Once again, bets are split down the middle, as 52% of bets are on the under. But generating 73% of the money, those bets are coming from the bigger, sharper bettors.

SI Bet Signals have also triggered a steam and reverse line move on the under — with no conflicting moves on the over — which has helped bring this total off the double-digit mark.

As for the reason for the wiseguy activity, Mother Nature is likely playing a role. A 7-8 mph breeze will be blowing straight in from centerfield throughout the game, providing a historically profitable opportunity. Since 2005, unders have won at a 55% clip when the wind blows straight in at 5-plus mph.

Sharp angle: Under (moved from 10 to 9.5)
