• The A's have seven players appearing on their first postseason roster: infielders Daric Barton and Eric Sogard ; catcher Stephen Vogt ; and pitchers Sonny Gray, Jesse Chavez, Dan Otero and Dan Straily.
Of the 25 players on the A's American League Division Series roster, 13 were on the A's ALDS roster last year. An additional five players (Alberto Callaspo, Bartolo Colon, Jed Lowrie, Kurt Suzuki, Chris Young ) have postseason experience with other teams.
• Bob Welch, who won a World Series championship with the A's in 1989, is slated to throw out the ceremonial first pitch before Game 2 on Saturday, airing at 6 p.m. PT on TBS.
Welch was 17-8 with a 3.00 ERA in 33 starts with the A's during their 1989 championship season and two years later was named the AL Cy Young Award winner after posting 27 wins and a 2.95 ERA.
Dave Henderson, who was also on that '89 team, threw out the first pitch at the Coliseum on Friday.
