Starting Pitchers

Janson Junk gets the ball for Miami and enters Monday at 6-7 with a 4.41 ERA and 1.32 WHIP through 87.2 innings. Junk has allowed 92 hits while recording 64 strikeouts against 24 walks and surrendering 12 home runs. Philadelphia counters with Cristopher Sanchez, who has been far more dominant at 15-4 with a 2.54 ERA and 1.19 WHIP over 155.2 innings. Sanchez has allowed 151 hits while striking out 181, walking 35 and giving up 13 home runs. Philadelphia clearly owns the starting-pitching advantage based on both run prevention and strikeout production.

Marlins Bring Better Team Pitching Numbers

Miami enters Monday slightly above .500 at 63-61 but has struggled on the road with a 25-36 record. The Marlins have won three of their last five games, including an 8-4 victory at Cincinnati in their most recent contest. Their other victories during that stretch came by scores of 8-2 and 2-0, while the two losses were 1-0 and 13-1. The recent results show a team capable of producing offense, but also one that has been inconsistent from game to game.

The Marlins are batting .250 with a .326 on-base percentage and .403 slugging percentage. They have collected 1,028 hits, scored 543 runs and hit 126 home runs. Miami's pitching staff has posted a 3.95 ERA and 1.24 WHIP while holding opposing hitters to a .231 average. The staff has recorded 1,037 strikeouts against 409 walks.

Miami's strength is that its overall team profile is better than its record might suggest. The Marlins own the superior team batting average, on-base percentage, slugging percentage, ERA, WHIP and opponent batting average in this matchup. The problem is that those broader advantages are offset by a difficult starting-pitching matchup and a poor road record. Miami needs to keep this game close early and avoid falling behind against Philadelphia's stronger starter.

Phillies Lean on the Stronger Starter

Philadelphia comes into this matchup at 66-58 overall and 32-30 at Citizens Bank Park. The Phillies have won three of their last five games and enter on a two-game winning streak after victories of 9-1 and 7-1. Their other win came by a 6-5 score, while the two losses were 7-1 and 2-0. Philadelphia has scored 23 runs over its last five contests, with most of that production coming in its three victories.

The Phillies are hitting .239 with a .310 on-base percentage and .401 slugging percentage. They have scored 551 runs on 993 hits while hitting 153 home runs. Philadelphia's pitching staff owns a 4.15 ERA and 1.30 WHIP while allowing opponents to bat .250. The Phillies have accumulated 1,222 strikeouts against 377 walks.

Philadelphia's biggest advantage is not necessarily its team-wide numbers but the matchup on the mound. The Phillies trail Miami in most of the broader pitching categories, but their starter enters with a 2.54 ERA and has recorded 181 strikeouts in 155.2 innings. Philadelphia also owns a notable power advantage with 153 home runs compared with Miami's 126. If the Phillies can combine that power with another strong starting performance, they should be in position to control this game.

Miami Marlins vs. Philadelphia Phillies Picks and Prediction

Pick: Philadelphia Phillies ML

Philadelphia is the preferred side in this matchup because the starting-pitching edge is too significant to ignore. The Phillies' starter enters at 15-4 with a 2.54 ERA and 1.19 WHIP, while Miami's starter owns a 4.41 ERA and 1.32 WHIP. Miami has stronger team pitching numbers overall and a better batting average, but its 25-36 road record is a concern. Philadelphia has also won two straight by comfortable margins and carries more home-run power into this matchup. The starting matchup gives the Phillies the edge.

Pick: Philadelphia Phillies ML

Pick: Under 8.0

The under is the stronger total lean if the number opens at eight. Miami has been involved in two shutouts over its last five games, while Philadelphia was also shut out once during that span. The Phillies' starter brings elite run-prevention numbers into this contest, and Miami's staff has posted a solid 3.95 team ERA with a 1.24 WHIP. Philadelphia's recent offensive outbursts are a concern, but the pitching matchup points toward a lower-scoring game than the recent scores alone might suggest.

Take the Under if the total is set at 8.0.
