The White Sox and Astros will meet in perhaps the most evenly matched series in the postseason. 

Chicago will be looking for its first postseason series win since 2005, when they won the World Series. Houston, a postseason staple of late, earns a spot for the sixth time in the last seven seasons. The Astros lost in the ALCS to the Tampa Bay Rays last year and will be looking to make a return to the World Series for the third time in five years. Houston lost to the Nationals in 2019 in the World Series but won it all in 2017 defeating the Los Angeles Dodgers.

Houston, which won five of seven games against the White Sox this season, is the second overall betting choice (+210) at SI Sportsbook to capture the American League Pennant — behind only Tampa Bay (+190). The keys to this series will be Lance McCullers and the Astros' experience, having won nine of the past 13 playoff series they have taken part in. In addition, the potential injury concern surrounding Carlos Rondon (shoulder) is a tremendous detriment for Chicago. If Rodon is not fully healthy in a five-game series, I expect it to be the difference in a close matchup.

BET: Houston Astros (-130)

After beating the Yankees in the AL wild-card game, Boston will now be on its way for a showdown with Tampa Bay. On Tuesday, it was learned that the Rays will be throwing their youngest arms in their postseason starting rotation. Rookie Shane McClanahan will take to the bump in Game 1, while the club’s prize prospect Shane Baz will be handed the ball in Game 2. McClanahan has earned the trust of the Rays after becoming the most consistent starter on the staff following the season-ending injury to Tyler Glasnow in June. Tampa Bay, which led the American League in wins (100) and run differential (+206) in the regular season, will now face its AL East foe who they have already beaten 11 times in 19 games. In fact, Tampa Bay has dominated Boston, going 11-4 in the final 15 regular season matchups. The Rays, despite the inexperience in their rotation, are perhaps the most complete team in the playoffs. Lay the juice.

BET: Tampa Bay (-145)
