Starting Pitchers

San Francisco is scheduled to start Landen Roupp, who enters at 9-13 with a 4.00 ERA and 1.28 WHIP through 150.2 innings. He has allowed 121 hits and 11 home runs while recording 139 strikeouts against 72 walks. St. Louis counters with Quinn Mathews, who is 1-3 with a 4.11 ERA and 1.50 WHIP across 30.2 innings. He has allowed 32 hits and three home runs while striking out 28 and walking 14. San Francisco has the starting-pitching edge based on the lower ERA, lower WHIP and significantly larger body of work.

San Francisco Has Controlled This Matchup

San Francisco enters Monday at 62-87 overall and just 26-49 away from home. The Giants have dropped their last two games, losing 7-6 and 7-5, but they are still 3-2 over their last five. Before those defeats, San Francisco swept St. Louis in three straight meetings by scores of 5-4 in 11 innings, 2-1 and 7-6. That recent head-to-head success is one of the strongest factors working in the Giants' favor.

The Giants are batting .247 with 628 runs, 1,248 hits and 171 home runs. They own a .308 on-base percentage and .408 slugging percentage. San Francisco's pitching staff carries a 4.37 ERA and 1.37 WHIP while opponents are batting .248. The staff has recorded 1,111 strikeouts against 557 walks, and the Giants are 23-35 in day games.

San Francisco's offense owns several small but meaningful statistical advantages. The Giants have the better batting average, more hits, more home runs and the higher slugging percentage. Their biggest concern remains run production, because those advantages have translated into only 628 runs. Still, the combination of better power numbers and the more established starting pitcher gives San Francisco a legitimate chance to continue its recent success against St. Louis.

St. Louis Needs to Reverse Its Recent Form

St. Louis enters Monday at 73-76 overall and 35-39 at Busch Stadium. The Cardinals have lost four of their last five games, with their only victory coming by a 7-3 score. Their four losses during the stretch came by scores of 6-5, 7-6, 2-1 and 5-4 in 11 innings. Three of those defeats came directly against San Francisco, making this a quick opportunity for St. Louis to respond after being swept on the road.

The Cardinals are batting .244 with 680 runs, 1,228 hits and 157 home runs. They carry a .317 on-base percentage and .386 slugging percentage. St. Louis owns a 4.31 team ERA and 1.35 WHIP while opponents are hitting .254. The pitching staff has recorded 1,179 strikeouts against 514 walks, and the Cardinals are 26-32 in day games.

St. Louis' biggest advantage is its ability to turn its offense into runs. The Cardinals have scored 52 more runs than San Francisco despite trailing the Giants in batting average, hits, home runs and slugging percentage. St. Louis also owns slightly better team ERA and WHIP numbers. The problem is recent execution, because the Cardinals just lost three consecutive games to this same opponent and have struggled to close out tight contests.

San Francisco Giants vs St. Louis Cardinals Picks and Prediction

Pick: San Francisco Giants Moneyline

The San Francisco Giants Moneyline is the preferred side. St. Louis has the better overall record and is at home, but San Francisco has already demonstrated that it matches up well with the Cardinals by sweeping three meetings just last week. The Giants also have the stronger scheduled starter, with advantages in ERA and WHIP, while San Francisco's offense holds the edge in batting average, hits, home runs and slugging percentage. Given the recent head-to-head results and starting-pitching advantage, the Giants offer the better side.

Pick: Over 8.5

Take the Over if the total is set at 8.5 or lower. Four of San Francisco's last five games have reached at least nine combined runs, including totals of 13, 12, 13 and nine. St. Louis has also played several higher-scoring games recently, with three of its last five finishing at 10 runs or more. Neither team owns an elite pitching profile, and both staffs carry ERAs above 4.30. With the recent head-to-head series producing two games of at least nine runs, the Over is the more attractive total position.
