While we’re technically well into the season’s second half based on the number of games played, the second half officially starts on Friday. The Astros find themselves in the thick of another tight AL West race, although it didn’t look like that would be the case only a month ago. Once trailing the division-leading Mariners by ten games on June 18, we’ve witnessed a stark reversal in fortune, with Houston posting a 17-6 record since then. It also helps Seattle was 8-15 during that same period. FanGraphs currently gives the edge to the Astros in overall postseason odds — 58.
