The Chicago White Sox tied the American League record for longest losing streak in history on Monday after a 5-1 loss to the Oakland Athletics resulted in their 21st straight defeat. Anyone who has been fading the White Sox in MLB parlay bets over the last three weeks has gotten at least one of their legs correct. The White Sox and A's have the two worst records in the AL, so it seems if there's a team Chicago can knock off before surpassing the longest losing streak since 1900, it would be Oakland. The White Sox plays the A's at 9:40 p.m. ET so with AL history at stake, should you include Oakland in your MLB parlay? Meanwhile, Framber Valdez takes the mound for the Houston Astros against the Texas Rangers at 8:05 p.m. ET and the LHP has struck out 10 batters in three of his last four starts, making this another intriguing matchup to include in MLB parlay bets.

The A's are -189 favorites (risk $189 to win $100) in the latest White Sox vs. Athletics odds, while the White Sox are +157 underdogs. The over/under for total runs scored is 8.5. The game is one of 15 on the packed MLB schedule for Tuesday evening. (See up-to-date lines for every game on our MLB odds page.)
