Players to Watch: Seattle Mariners vs. Colorado Rockies
Seattle Mariners
Randy Arozarena — LF. Arozarena patrols left field for Seattle and doubles as the lineup’s most complete hitter, batting .278 with 25 home runs and 75 RBIs. His .375 on-base percentage and .476 slugging percentage round out a well-balanced offensive game.
Cal Raleigh — C. Behind the plate, Raleigh has produced 22 home runs and 66 RBIs this season, making him Seattle’s primary power threat from the catcher spot. That production has come despite a .182 batting average, with his .295 on-base percentage reflecting a season built on damage over average.
Cole Young — 2B. Young has scored 71 runs from the second base spot while hitting .247 with 17 home runs and 65 RBIs. His .309 on-base percentage and .387 slugging percentage make him a steady presence at the top of Seattle’s order.
Colorado Rockies
TJ Rumfield — 1B. Rumfield has been the Rockies’ most consistent hitter this season, batting .301 with a .393 on-base percentage from first base. His .456 slugging percentage adds pop to an otherwise steady approach at the plate.
Hunter Goodman — C. Goodman’s bat has carried Colorado’s lineup from behind the plate, with 38 home runs and 81 RBIs against a .245 average. His .529 slugging percentage and .312 on-base percentage reflect a hitter who trades average for damage every time he connects.
Cole Carrigg — CF. Carrigg brings speed to the middle of Colorado’s lineup, stealing 9 bases while hitting .266 with 10 home runs and 45 RBIs in center field. His .465 slugging percentage and .333 on-base percentage give the Rockies a table-setter capable of extra-base damage too.
