Excluding the WC round (which obviously made this more common), Aaron Civale is the 4th pitcher in MLB history to make postseason debut as a SP in a winner-take all game, joining:
With his walk-off single against the Yankees in Game 3, Oscar Gonzalez tied the single-season and career records for postseason go-ahead RBI in the 9th inning or later with three.
Steven Kwan is the third rookie in franchise history with a postseason home run, joining Oscar Gonzalez (earlier this postseason vs Rays) and Asdrubal Cabrera (2007 against the Yankees).
Bryan Shaw is the oldest pitcher to make his first career start for Cleveland since Doug Jones (also 34) in 1991.
Jones, an All-Star from 1988-90, was awful in 1991. So he was demoted to AAA, turned into a starter and returned in September.
Jones threw 8 2/3 innings against Milwaukee in his debut as a starter, picking up the win. Then he struck out 13 Tigers in 8 innings in his second outing.
He made 2 more starts, going 3-1 overall with a 3.77 ERA before he returned to closer duties in his final outing of the year.
He signed with Houston that offseason and returned to All-Star closer form.
Sandy Leon is the first Cleveland position player to toss two scoreless innings since Willie Smith in 1968. But that deserves as asterisk since Smith started his MLB career as a pitcher.
Prior to Smith, it was Rocky Colavito in 1958 vs Detroit.
Nolan Jones joins Roy Weatherly (1936) as the only players in franchise history with at least two hits, including an extra-base hit and an RBI in each of their first two career games.
Weatherly became a fixture in the Indians lineups, often as their leadoff hitter though the late 1930s and early 40s. He was traded to the Yankees prior to the 1943 season, and helped them win the World Series that year.
