Updated Oct. 19, 2021 4:16 p.m. ET

The Boston Red Sox are having a grand time at the expense of the Houston Astros in the American League Championship Series.

Here's everything you need to know about the MLB odds on Tuesday's matchup between the Red Sox and Astros — the point spread, moneyline, total over/under, and pick from our betting expert (with all odds via FOX Bet).

Kyle Schwarber hit a grand slam in Boston's 12-3 victory Monday in Game 3 for a 2-1 series lead. Boston, who hit four homers in Game 3, is the first team with three slams in a postseason series.

Boston's key in its two ALCS victories? A quick start — the Red Sox have led 9-0 in both games en route to 9-5 and 12-3 wins.

Houston is slated to send right-hander Zack Greinke (11-6, 4.16 ERA in regular season) against Boston right-hander Nick Pivetta (9-8, 4.53 ERA) for Game 4.

This season, Greinke, who had a pair of injured list stints in September, has one postseason appearance. The 2009 American League Cy Young winner pitched one inning of relief in Game 3 of the ALDS. He permitted two hits but no runs against the White Sox.

Pivetta has struck out 11 of the 34 batters he's faced while yielding three runs on seven hits and three walks this postseason.

Boston's Kiké Hernández is batting .500 (18-for-36) this postseason. Houston's top hitter this postseason (with at least 20 at-bats) is shortstop Carlos Correa (9-for-25, .360, one homer, five RBIs).

Houston pitcher Lance McCullers Jr. has tightness in his flexor tendon area and is likely unavailable until Game 7 at the earliest. In seven potential series clinchers, McCullers has a 2.96 ERA.
