Cole Hamels struggled in 94-degree heat and the Phillies failed to go two games over .500 for the first time this year in a 5-4 loss to the Mets on Saturday.
The Phillies conclude their three-game series with the Mets at 1:10 p.m. on Sunday.
Here are a few other MLB games to keep an eye on:
Yankees at Red Sox, 8:05 p.m.
CC Sabathia used a Caribbean vacation to get away from baseball during the All-Star break.
He'll be back on the mound in a place that has been unkind to him since he joined the New York Yankees.
Sabathia will try to avoid losing three straight starts with the Yankees for the first time in Sunday night's road game against the Boston Red Sox.
The left-hander's run of three straight All-Star appearances came to an end this year. Sabathia (9-8, 4.07 ERA) went into the break with two straight defeats, and hasn't dropped three in a row since April 5-16, 2008, with Cleveland.
He was in St. Barts island in the Caribbean over this break (see full preview).
Orioles at Rangers, 7:05 p.m.
With a chance to complete a road sweep of one of the best teams in the AL, the Baltimore Orioles will start one of the most successful pitchers of the past two years.
Chris Tillman heads into Sunday night seeking his ninth win in 10 decisions for the Orioles, who look to make it five straight victories over the struggling Texas Rangers.
Baltimore (55-43) has won four in a row in this season series after losing the first two meetings. The Orioles scored in each of the first three innings for a 7-0 lead Saturday and held on for a 7-4 victory to move a season-best 12 games over .500.
Adam Jones homered for the fourth time in five games and Matt Wieters had three of the Orioles' 17 hits (see full preview).
Diamondbacks at Giants, 4:05 p.m.
As bad as the San Francisco Giants were in June and earlier this month, a recent surge has brought them closer to the top of the NL West.
They hope to make up more ground Sunday as Madison Bumgarner tries to clinch a sweep of the division-leading Arizona Diamondbacks at AT&T Park.
The Giants (45-51) followed a 10-17 month of June by starting 1-8 in July, but won three of four before the All-Star break. Back-to-back wins over the Diamondbacks (50-47) - including a 4-3 victory on Saturday - have them 4 1/2 games out of first place. Pablo Sandoval and Buster Posey were a combined 4 for 8 with three RBIs (see full preview).
