Colorado Rockies Bring a Productive Lineup

Colorado ranks third in MLB with a .255 batting average and has scored 577 runs with 137 home runs. Hunter Goodman leads the power numbers with 34 homers and 69 RBIs, while Jake McCarthy is batting .300 with a .337 on-base percentage, .505 slugging percentage, and 20 stolen bases. TJ Rumfield is another steady bat, hitting .294 with a team-high .371 on-base percentage. The Rockies scored 21 runs over their last five games and won their last two against Arizona.

Pitching remains Colorado’s biggest problem. The Rockies rank 29th in MLB with a 5.47 ERA and 1.52 WHIP while opponents are batting .288. Michael Lorenzen gets the start. Colorado is also just 21-41 away from home and 15-26 in day games.

San Francisco Giants Have the Starting Pitching Edge

San Francisco is batting .248 with a .306 on-base percentage and .406 slugging percentage while scoring 493 runs with 134 homers. Rafael Devers leads the Giants with 24 home runs and 64 RBIs, while Luis Arraez is batting .324 with a .360 on-base percentage. Jung Hoo Lee is hitting .293, giving San Francisco another consistent contact bat. The offense has struggled lately, scoring only nine runs across the last five games while going 1-4.

The Giants rank 21st in MLB pitching with a 4.31 ERA and 1.35 WHIP, numbers well ahead of Colorado’s staff. San Francisco is 28-31 at Oracle Park and 20-27 in day games. Logan Webb gives San Francisco a clear advantage on the mound. 

Pitching Matchup

Colorado Rockies – Michael Lorenzen

Lorenzen enters with a 6.83 ERA and has allowed 164 hits in only 112 innings. His 1.88 WHIP is especially concerning against a Giants lineup featuring Arraez, Lee and Devers. San Francisco has not scored much recently, but Lorenzen’s season numbers give the Giants a good opportunity to improve offensively.

San Francisco Giants – Logan Webb

Webb has a 3.59 ERA and 1.08 WHIP with only nine home runs allowed across 133 innings. Colorado owns a strong .744 team OPS, but Webb has limited traffic far better than Lorenzen. Keeping Goodman and McCarthy from producing extra-base hits will be important against a Rockies lineup ranked among MLB’s better hitting clubs.

Colorado Rockies vs San Francisco Giants Game Pick

• San Francisco Giants

San Francisco is the game pick because Webb provides a major starting-pitching advantage over Lorenzen. Webb’s 3.59 ERA and 1.08 WHIP compare favorably with Lorenzen’s 6.83 ERA and 1.88 WHIP. Colorado has the stronger offense statistically, but the Rockies are only 21-41 on the road and own the second-highest team ERA in MLB. Those pitching numbers make San Francisco the stronger play Saturday.

Colorado Rockies vs San Francisco Giants Over/Under Pick

• Over

The over is the preferred total pick because Colorado games carry plenty of scoring potential from both sides. The Rockies have scored 577 runs and rank third in batting average, but their pitching staff owns a 5.47 ERA and has allowed opponents to hit .288. Lorenzen’s 6.83 ERA creates the biggest reason to expect runs, while Colorado’s lineup has enough production to contribute even with Webb starting for San Francisco.
