Philadelphia, meanwhile, is playing under interim manager Don Mattingly, who took over the dugout in April after the club started 9-19 under Rob Thomson — and the Phillies have steadied since, sitting well above .500 and chasing Atlanta in a real NL East race down the stretch. Kyle Schwarber is currently tied with Houston's own Yordan Álvarez for the major league home run lead, and Sánchez — an All-Star this year who started the Midsummer Classic on his own mound at Citizens Bank Park — gives Philadelphia a legitimate ace to lean on against a Houston lineup that has gone cold at the worst possible time.
There's a little extra juice here, too — Houston and Philadelphia met in the 2022 World Series, and both clubs come into this series with real playoff hopes attached, which only raises the stakes on what's turned into a get-right spot for an Astros offense that has struggled to score all month.
Whatever happens in Tuesday's opener, Wednesday's game likely comes down to which offense snaps out of its funk first — the Phillies looking to build on their most recent win, the Astros trying to prove their September cold spell is a blip and not a trend. Neither roster is at full strength up and down the depth chart, so the players who are healthy and available carry more weight than usual in this one.
