Red Sox vs. Rockies Prediction, Winner Payout, Over/Under – Tuesday, June 23

In Tuesday’s matchup, Red Sox SP Sonny Gray (3.83 xFIP across 69.1 innings) will go head-to-head with Rockies SP Sean Sullivan (7.52 xFIP in 7.0 innings) on the mound.

Gray has allowed 1 or fewer earned runs in five of his last eight starts while yielding no more than 3 earned runs in any start during that stretch. He's relied heavily on the ground ball in 2026, inducing a 48.1% clip (76th percentile).

Meanwhile, Sullivan was called up by the Rockies earlier this month and has surrendered 8 earned runs across two MLB starts. According to MLB.com, Sullivan was ranked as the Rockies’ No. 11 prospect entering the 2026 campaign.

Offensively, the Red Sox have been one of the poorer lineups around the majors, ranking 29th in wRC+ (88) and scoring the fewest runs (294) in all of baseball.
