Starting Pitchers

Houston is scheduled to start Peter Lambert, who enters at 8-5 with a 3.06 ERA and 1.13 WHIP through 108.2 innings. Lambert has allowed only 82 hits and 11 home runs while recording 108 strikeouts against 41 walks. He has done an excellent job limiting contact this season, and his numbers give Houston a considerable advantage over what the Astros' overall pitching statistics might suggest.

San Diego will counter with Michael King, who is 6-8 with a 3.45 ERA and 1.20 WHIP through 130.1 innings. King has allowed 102 hits and 14 home runs while recording 114 strikeouts against 54 walks. He has also been effective at keeping hitters off base, although Lambert enters with advantages in ERA and WHIP. This shapes up as a quality starting pitching matchup between two right-handers who have allowed fewer hits than innings pitched.

Astros Bring the Stronger Offensive Numbers

Houston enters the weekend at 59-57 overall and 29-28 on the road. The Astros are 3-2 over their last five completed games after losing 5-4 in 10 innings against Toronto on Wednesday. Houston beat the Blue Jays 7-2 in the previous game after a 3-1 loss in the series opener. The Astros also picked up consecutive victories over Texas by scores of 7-3 and 5-4. Houston has scored 24 runs across those five games.

The Astros are batting .246 with a .322 on-base percentage and .416 slugging percentage this season. Houston has scored 540 runs on 965 hits while hitting 157 home runs. The pitching staff owns a 4.60 ERA and 1.36 WHIP with 1,020 strikeouts and 484 walks. Opposing hitters are batting .237 against Houston pitching.

Houston's offense provides its clearest overall advantage. The Astros have scored 49 more runs and hit 35 more home runs than San Diego while also owning the better batting average, on-base percentage and slugging percentage. Their 4.60 team ERA is a concern, but Lambert has been substantially better than that season-long number. If he continues pitching at his current level, Houston has a good opportunity to turn its offensive advantage into a road victory.

Padres Lean on Pitching and Home-Field Advantage

San Diego enters the weekend at 60-56 overall and 32-25 at Petco Park. The Padres are also 3-2 over their last five completed games and are coming off a 5-1 victory over Arizona. San Diego alternated wins and losses throughout that five-game stretch, beating Arizona 9-4 and San Francisco 5-4 while suffering losses of 10-4 and 5-1 against the Diamondbacks.

The Padres are batting .236 with a .313 on-base percentage and .383 slugging percentage. San Diego has scored 491 runs on 903 hits while hitting 122 home runs. The Padres' pitching staff owns a 4.18 ERA and 1.33 WHIP with 942 strikeouts and 401 walks. Opposing hitters are batting .248 against San Diego pitching.

San Diego's overall pitching numbers are better than Houston's, and the Padres have played winning baseball at Petco Park. The question is whether their offense can generate enough production against Lambert. San Diego trails Houston in every major offensive category provided by ESPN, including runs, hits, home runs, batting average, on-base percentage and slugging percentage. King gives the Padres a chance to keep the game close, but San Diego could have difficulty separating from Houston if Lambert pitches to his season numbers.

Houston Astros vs San Diego Padres Picks and Prediction

• Pick: Houston Astros Moneyline (+104)

I'm taking the Houston Astros at +104. San Diego has the better overall pitching numbers and the stronger home record, but Houston has the advantage I value most in this particular matchup: Lambert plus the better offense.

Lambert enters at 8-5 with a 3.06 ERA and 1.13 WHIP while allowing only 82 hits through 108.2 innings. Houston has also scored 49 more runs than San Diego and hit 35 more home runs. King is certainly capable of keeping the Padres competitive, but getting plus money on the team with the stronger offensive numbers and the starter with the better ERA and WHIP gives me enough value to take Houston.

• Pick: Under 8 (-115)

I'm taking the Under 8 at -115. Both starting pitchers have put together strong seasons, with Lambert carrying a 3.06 ERA and 1.13 WHIP and King entering with a 3.45 ERA and 1.20 WHIP. Neither starter has allowed a high number of hits, which should help limit sustained scoring opportunities.

San Diego's offensive numbers also point me toward the Under. The Padres are batting .236 with a .313 on-base percentage and have scored 491 runs through 116 games. Houston has considerably more power, but King has allowed only 102 hits and 14 home runs through 130.1 innings. With two capable starters on the mound at Petco Park, I'll take the Under 8.
