Starting Pitchers

Houston is scheduled to start Hayden Wesneski, who enters at 5-1 with a 3.35 ERA and 1.03 WHIP through 45.2 innings. He has allowed 33 hits and three home runs while recording 36 strikeouts against 14 walks. Tampa Bay counters with Freddy Peralta, who is 8-11 with a 4.82 ERA and 1.36 WHIP across 153 innings. He has surrendered 153 hits and 23 home runs while striking out 142 and walking 55. Houston has the statistical starting-pitching advantage based on the numbers provided, although its starter has worked considerably fewer innings.

Houston Needs Its Pitching Edge to Travel

Houston enters Sunday at 75-73 overall and 38-35 away from home. The Astros have gone 2-3 over their last five games after losing the series opener in Tampa Bay 3-1. Their other recent losses came by scores of 11-7 and 3-2, while their victories were 2-1 and 6-5. Four of those five games were decided by two runs or fewer, showing how frequently Houston has found itself in close contests.

The Astros are batting .241 with 663 runs, 1,200 hits and 193 home runs. They own a .315 on-base percentage and .409 slugging percentage. Houston's pitching staff has a 4.51 ERA and 1.34 WHIP while opponents are batting .238. The staff has recorded 1,296 strikeouts against 598 walks, and Houston owns a 24-25 record in day games.

Houston's biggest offensive advantage is its power. The Astros have hit 36 more home runs than Tampa Bay and also carry the slightly better slugging percentage. The problem is preventing runs consistently, as Houston's 4.51 team ERA and 1.34 WHIP are considerably weaker than Tampa Bay's marks. For the Astros to reverse the series opener, they likely need their starting-pitching advantage to hold long enough for the power offense to make a difference.

Tampa Bay Continues to Win With Balance

Tampa Bay enters Sunday at 88-59 overall and 48-25 at Tropicana Field. The Rays have won three of their last five games, including the 3-1 victory over Houston in the series opener. They also recorded consecutive 7-2 and 7-1 victories during that stretch, while their two losses came by scores of 3-1 and 8-6. Tampa Bay has therefore held three of its last five opponents to two runs or fewer.

The Rays are batting .260 with 665 runs, 1,284 hits and 157 home runs. They have a .328 on-base percentage and .404 slugging percentage. Tampa Bay's pitching staff owns a 3.79 ERA and excellent 1.15 WHIP while opponents are batting just .231. The Rays have collected 1,183 strikeouts against only 367 walks and enter with a 31-27 record in day games.

Tampa Bay's strength is the completeness of its statistical profile. The Rays own the better batting average and on-base percentage while essentially matching Houston in total runs, and their pitching numbers are substantially stronger. Tampa Bay also has a 48-25 home record compared with Houston's 38-35 road mark. The main concern is Sunday's starting matchup, where the numbers favor the visitors, but the Rays have enough advantages elsewhere to offset some of that difference.

Houston Astros vs Tampa Bay Rays Picks and Prediction

Pick: Tampa Bay Rays Moneyline

The Tampa Bay Rays Moneyline is the preferred side despite Houston owning the better statistical starting-pitching matchup. Tampa Bay has been the substantially stronger team over the full season, carries a 48-25 home record and owns significant advantages in team ERA, WHIP and opponent batting average. The Rays also have the better batting average and on-base percentage and already held Houston to one run in the series opener. Houston can make this competitive, but Tampa Bay's overall balance and home-field performance give the Rays the edge.

Pick: Under 8.5

Take the Under if the total is set at 8.5 or higher. Houston's scheduled starter brings a 3.35 ERA and 1.03 WHIP into the matchup, while Tampa Bay has allowed two runs or fewer in three of its last five games. The Rays also own a 3.79 team ERA and 1.15 WHIP for the season. Four of Houston's last five games have finished with eight or fewer combined runs, including the 3-1 series opener, giving the Under value if the market provides an 8.5 or better.
