Starting Pitchers

Landen Roupp is scheduled to start for San Francisco and enters at 8-13 with a 4.25 ERA and 1.31 WHIP over 139.2 innings.

Jared Jones gets the start for Pittsburgh and is 2-6 with a 4.83 ERA and 1.28 WHIP across 72.2 innings. He has allowed 66 hits with 83 strikeouts, 27 walks and 12 home runs. Neither starter has dominant season numbers, although San Francisco's starter has worked considerably more innings while Pittsburgh's starter owns the slightly better WHIP.

Giants Trying to Extend Their Winning Streak

San Francisco enters Wednesday at 57-81 overall and 24-45 on the road. The Giants sit fourth in the NL West and are 25.5 games behind Los Angeles, but their recent play has improved. San Francisco has gone 3-2 over its last five games and enters this matchup on a two-game winning streak after beating Arizona 7-2 and Atlanta 7-3. The Giants also own the season-series advantage against Pittsburgh through the first three completed meetings.

The Giants are batting .247 with 567 runs, 1,156 hits and 155 home runs. They carry a .307 on-base percentage and .406 slugging percentage. San Francisco's slugging percentage is actually slightly better than Pittsburgh's .404 mark, but the Giants have scored 102 fewer runs. The largest offensive concern is their ability to consistently create baserunners, as their .307 OBP trails Pittsburgh's .329 mark by a significant margin.

San Francisco's pitching staff owns a 4.34 ERA and 1.35 WHIP while allowing opponents to bat .248. The Giants have issued 507 walks against 1,041 strikeouts, leaving them well behind Pittsburgh in strikeout production. San Francisco has shown better form recently, but a 24-45 road record remains difficult to overlook. The Giants will need another efficient pitching performance to overcome their season-long problems away from home.

Pirates Have the Home-Field Edge

Pittsburgh comes into Wednesday at 67-71 overall and 34-32 at PNC Park. The Pirates are fourth in the NL Central, 18 games behind Milwaukee, but they have won two straight and three of their last five games. Pittsburgh closed its recent series in St. Louis with consecutive victories by scores of 6-2 and 5-4. The Pirates have also been much more competitive at home than San Francisco has been on the road, giving Pittsburgh an important situational advantage.

The Pirates are batting .252 with 669 runs, 1,197 hits and 162 home runs. Pittsburgh has a .329 on-base percentage and .404 slugging percentage. While the power numbers are relatively close between these teams, Pittsburgh has been considerably more productive overall, scoring 102 more runs than San Francisco. The Pirates also hold advantages in batting average, hits and on-base percentage, providing them with the more consistent offensive profile.

Pittsburgh's pitching staff has produced a 4.19 ERA and 1.31 WHIP while holding opponents to a .237 batting average. The Pirates have issued 505 walks and collected 1,270 strikeouts. That strikeout total is 229 higher than San Francisco's despite the walk totals being almost identical. Pittsburgh's combination of better run production, stronger overall run prevention and a winning home record makes the Pirates the more attractive side in this matchup.

San Francisco Giants vs Pittsburgh Pirates Picks and Prediction

Pick: Pittsburgh Pirates Moneyline

The Pittsburgh Pirates Moneyline is the preferred side. San Francisco has played better recently and owns the advantage in the completed season-series meetings, but the broader numbers favor Pittsburgh. The Pirates have a 10-win advantage in the standings, are 34-32 at PNC Park and have scored 102 more runs than the Giants. Pittsburgh also owns the better team ERA, WHIP and opponent batting average, while ESPN Analytics gives the Pirates a substantial 63.0% win probability. With San Francisco just 24-45 away from home, take the Pittsburgh Pirates Moneyline.

Pick: Under 8.5

The Under 8.5 is the preferred total if the number is available around that mark. Pittsburgh has a 4.19 team ERA and has allowed opponents to bat only .237, while San Francisco has scored just 567 runs through 138 games. The Giants have also shown enough pitching capability recently to keep games manageable, and neither offense has overwhelming home-run production. The starting-pitching matchup carries some risk for an Under, but Pittsburgh's superior pitching profile and San Francisco's inconsistent offense provide enough support for a lower-scoring projection. Take the Under if the total is set at 8.5.
