Starting Pitchers

Philadelphia's starting pitcher remains undecided for Friday's matchup. New York is scheduled to start Zac Thornton, who enters at 4-5 with a 3.44 ERA and 1.16 WHIP through 73.1 innings. Thornton has allowed 69 hits and 12 home runs while recording 55 strikeouts against only 16 walks. His control has been one of the better elements of his statistical profile, but the Phillies' undecided starter makes a direct comparison impossible at this stage. That uncertainty is important when evaluating both the side and total, particularly with no confirmed betting lines available yet.

Philadelphia Looks to Build on a Shutout Win

Philadelphia enters Friday at 84-68 and has gone 2-3 over its five most recently completed games. The Phillies defeated Washington 3-0 on Wednesday after losing 6-3 the previous night. Before that series, Philadelphia went 1-2 in three completed games at Atlanta, including a 9-4 victory sandwiched between losses of 6-5 in 11 innings and 12-2. Despite the uneven recent stretch, Philadelphia remains 15 games above .500 and has been effective away from home with a 43-34 road record.

The Phillies are batting .241 with 1,230 hits, 681 runs and 177 home runs while carrying a .312 on-base percentage and .399 slugging percentage. Their pitching staff owns a 3.99 ERA and 1.28 WHIP, with opponents batting .247. Philadelphia has issued 454 walks while recording 1,476 strikeouts. The Phillies also enter with a 59-44 record in night games.

Philadelphia doesn't hold enormous statistical advantages offensively, but it does have small edges over New York in batting average, on-base percentage, slugging percentage and runs scored. The more meaningful difference may be the overall consistency of the pitching staff, where Philadelphia's 3.99 ERA compares favorably with New York's 4.18. The Phillies have also demonstrated that they can win away from home, while the Mets enter this matchup nine games below .500 at Citi Field. Philadelphia's biggest question is the unannounced starter, but the broader team profile still gives the Phillies several advantages.

New York Tries to Stop a Four-Game Slide

New York enters Friday at 69-83 and has lost four consecutive games among the completed results provided. The Mets were swept in a three-game home series against Baltimore, falling 2-1, 7-5 in 11 innings and 7-1. That skid began after a 2-0 loss at the Yankees, leaving New York 1-4 over its last five completed games. The Mets' only victory during that stretch was a 12-2 win against the Yankees. New York has also struggled to establish a meaningful home-field advantage, going 34-43 at Citi Field.

The Mets are batting .238 with 1,220 hits, 650 runs and 190 home runs. They own a .308 on-base percentage and .394 slugging percentage. On the pitching side, New York has posted a 4.18 ERA and 1.30 WHIP while allowing opponents to hit .241. The Mets have issued 518 walks against 1,366 strikeouts and are 38-53 in night games.

Power is one statistical area where New York holds an advantage, with 190 home runs compared with Philadelphia's 177. The problem is that the additional power has not produced more overall offense, as the Mets have scored 31 fewer runs. New York also has the slightly worse ERA and WHIP, and its 518 pitching walks are considerably higher than Philadelphia's 454. The scheduled starter gives New York some stability entering the matchup, but the Mets' recent losing streak and 34-43 home record make it difficult to overlook their broader disadvantages.

Philadelphia Phillies vs New York Mets Picks and Prediction

Pick: Philadelphia Phillies Moneyline

Philadelphia is the side to back if the eventual moneyline remains reasonable. The Phillies have the superior overall record at 84-68 compared with New York's 69-83 and have actually performed better on the road at 43-34 than the Mets have at home at 34-43. Philadelphia also owns modest advantages in batting average, on-base percentage, slugging percentage, runs scored, ERA and WHIP. New York has lost four straight completed games, while Philadelphia is coming off a shutout victory. The uncertainty surrounding Philadelphia's starter prevents this from being an aggressive recommendation before prices are posted, but the team-level numbers favor the Phillies.

Pick: Under 8.5 or Higher

The Under is the preferred total if sportsbooks post 8.5 or higher. New York's scheduled starter carries a 3.44 ERA and 1.16 WHIP, while Philadelphia's pitching staff has produced a 3.99 ERA for the season. The Mets have scored only seven combined runs across their four-game losing streak, including one run or fewer in three of those games. Philadelphia's most recent game ended 3-0, and five of the nine completed meetings between these teams this season have finished with seven runs or fewer. Because Philadelphia's starter remains undecided, there is not enough information to chase an especially low total, but 8.5 provides a more attractive target for an Under position.

Final Picks: Philadelphia Phillies Moneyline and Under 8.5 or Higher
