Starting Pitchers

Logan Webb is scheduled to start for San Francisco and enters at 8-8 with a 3.72 ERA and 1.10 WHIP across 147.2 innings. He has allowed 127 hits while recording 118 strikeouts against 36 walks and has surrendered 11 home runs. Paul Skenes gets the start for Pittsburgh and enters at 9-11 with a 3.79 ERA and 1.12 WHIP through 145 innings. He has allowed 121 hits while producing 175 strikeouts against 41 walks and 14 home runs. The run-prevention numbers are remarkably close, although Pittsburgh owns the clear strikeout advantage in this matchup.

Giants Continue to Struggle Away From Home

San Francisco enters Tuesday at 56-81 and sits 26 games behind first place in the National League West. The Giants have been particularly ineffective away from home, going only 23-45 on the road. They are 2-3 across their last five completed games, with wins of 7-2 and 6-1 over Arizona mixed around losses of 7-1, 10-6 and 10-9.

The Giants are batting .247 with 560 runs, 1,145 hits and 152 home runs. They own a .307 on-base percentage and .405 slugging percentage. Their power production has been respectable, but overall scoring has remained inconsistent and they enter this matchup with 109 fewer runs than Pittsburgh.

San Francisco's pitching staff owns a 4.35 ERA and 1.36 WHIP while allowing opponents to bat .248. The Giants have issued 506 walks against 1,031 strikeouts. Their biggest concern is that even with a quality starter scheduled for Tuesday, the full-game numbers remain weaker than Pittsburgh's in both run prevention and overall offensive production.

Pirates Bring the Better Overall Profile

Pittsburgh enters at 67-71 and sits fourth in the National League Central. The Pirates are 34-32 at PNC Park and have won two straight, beating St. Louis 5-4 and 6-2. They are 3-2 over their last five completed games, with the other victory coming 1-0 at San Diego.

The Pirates are batting .252 with 669 runs, 1,197 hits and 162 home runs. They own a .329 on-base percentage and .404 slugging percentage. Pittsburgh holds the advantage over San Francisco in batting average, on-base percentage, total hits, home runs and runs scored.

Pittsburgh also owns the stronger overall pitching profile with a 4.19 ERA and 1.31 WHIP while holding opponents to a .237 batting average. The Pirates have recorded 1,270 strikeouts against 505 walks. Those full-season numbers, combined with the better home record and recent form, give Pittsburgh the more complete statistical profile entering Tuesday.

San Francisco Giants vs Pittsburgh Pirates Picks and Prediction

Pick: Pittsburgh Pirates Moneyline

I'm backing the Pittsburgh Pirates Moneyline. The starting pitchers are close statistically, so this isn't simply a pitching mismatch, but Pittsburgh owns the stronger full-game profile. The Pirates are 34-32 at home compared with San Francisco's 23-45 road record, have scored 109 more runs and own the better team ERA, WHIP and opponent batting average. Pittsburgh has also won two straight and three of its last five. San Francisco's starter gives the Giants a chance to remain competitive early, but over nine innings I prefer the home team. Take the Pittsburgh Pirates Moneyline.

Pick: Under 8.5

I'm targeting Under 8.5 because the starting pitching matchup is considerably stronger than the teams' overall records suggest. San Francisco's starter enters with a 3.72 ERA and 1.10 WHIP, while Pittsburgh's starter carries a 3.79 ERA and 1.12 WHIP with 175 strikeouts in 145 innings. Pittsburgh has also played several low-scoring games recently, including three of its last five finishing with six combined runs or fewer. A game in the neighborhood of 4-2 or 4-3 fits the matchup. Take the Under if the total is set at 8.5.
