Starting Pitchers

San Francisco is scheduled to start Anthony Molina, who enters at 3-1 with a 5.24 ERA and 1.25 WHIP through 22.1 innings. He has allowed 23 hits and three home runs while recording 19 strikeouts against five walks. St. Louis counters with Matthew Liberatore, who is 5-14 with a 5.53 ERA and 1.49 WHIP through 143.1 innings. He has surrendered 161 hits and 27 home runs while striking out 146 and walking 52. Neither starter enters with especially strong run-prevention numbers, but Molina has the better ERA and WHIP while showing much better control in his limited workload. Liberatore offers substantially more innings and strikeout volume, although his 1.49 WHIP and 27 home runs allowed create opportunities for the Giants.

San Francisco Tries to Stop a Four-Game Slide

San Francisco enters Wednesday on a four-game losing streak and has gone 1-4 over its last five. The Giants lost the completed series opener 2-1 after being swept in three games by San Diego, falling 6-4, 7-6 and 7-5. Their lone victory during the five-game stretch was a 7-6 win over St. Louis on September 9. The Giants' 26-50 road record is another concern as they attempt to end their current slide at Busch Stadium.

The Giants are batting .247 as a team with 633 runs, 1,263 hits and 172 home runs. They own a .308 on-base percentage and .406 slugging percentage. San Francisco's pitching staff carries a 4.37 ERA and 1.36 WHIP while allowing opponents to bat .249. The staff has recorded 1,127 strikeouts against 562 walks, and the Giants are just 23-36 in day games.

San Francisco's most notable statistical advantage comes from its power. The Giants have hit 172 home runs compared with 157 for St. Louis and own the better slugging percentage at .406. Their recent offense hasn't been completely dormant either, scoring 22 runs over the last five games. The problem has been preventing runs consistently enough to turn that production into victories. San Francisco has surrendered at least six runs in four of those five contests, leaving little margin for error.

St. Louis Has an Opportunity to Stay Hot at Home

St. Louis enters at 75-76 overall and 37-39 at Busch Stadium. The Cardinals have won two consecutive games and are 3-2 over their last five. They defeated San Francisco 2-1 in the completed series opener after beating Chicago 3-1. St. Louis also defeated the White Sox 7-3 during this stretch, with its two losses coming 6-5 against Chicago and 7-6 at San Francisco.

The Cardinals are batting .243 with 685 runs, 1,240 hits and 157 home runs. They carry a .317 on-base percentage and .384 slugging percentage. St. Louis owns a 4.27 team ERA and 1.35 WHIP while opponents are batting .253. The pitching staff has recorded 1,200 strikeouts against 523 walks, and the Cardinals are 27-32 in day games.

St. Louis has scored 52 more runs than San Francisco despite having fewer hits, fewer home runs and a lower slugging percentage. The Cardinals also have modest advantages in team ERA and WHIP, and their recent form is substantially better. Wednesday's biggest concern is the starting matchup because their scheduled starter has struggled with traffic on the bases and home runs. Still, St. Louis has been the more dependable team overall and enters with momentum while San Francisco continues searching for a way out of its losing streak.

San Francisco Giants vs St. Louis Cardinals Picks and Prediction

Pick: St. Louis Cardinals Moneyline

Take the St. Louis Cardinals Moneyline. The starting-pitching matchup doesn't provide a major reason to lay a substantial price with St. Louis, but the broader team profile favors the Cardinals. St. Louis is 13 games better in the standings, has won two straight and owns modest advantages in team ERA and WHIP. San Francisco has lost four consecutive games and is only 26-50 away from home. With the betting line unavailable, the straight moneyline is the preferred side rather than trying to project a run-line price.

Pick: Over 8.5 or Lower

Take the Over if the total is set at 8.5 or lower. Both scheduled starters enter with ERAs above 5.20, and the two pitching staffs have team ERAs above 4.25. San Francisco has also been involved in several higher-scoring games recently, with four of its last five producing at least 10 combined runs. St. Louis has seen three of its last five reach at least 10 combined runs as well. The completed series opener finished only 2-1, but Wednesday's pitching matchup creates a much different scoring profile.

Final Picks: St. Louis Cardinals Moneyline and Over 8.5 or Lower
