The Phillies arrive in Atlanta carrying an 82-67 record and a three-game losing streak. The Braves counter at 88-61 with a three-game winning streak. First pitch is set for 1:35 PM ET at Truist Park, where the park factor sits at an even 1.00 for runs. Andrew Painter takes the ball for Philadelphia with a 5.71 ERA, 1.41 WHIP, and 7.91 strikeouts per nine innings. Grant Holmes counters for Atlanta with a 3.46 ERA, 1.29 WHIP, and 7.19 strikeouts per nine. The K model projects Painter at 3.9 strikeouts against a posted line of 4.0, landing neutral with medium confidence. Holmes projects at 2.6 strikeouts against the same 4.0 line, a stronger lean toward the under at six out of ten confidence. Bullpen fatigue splits sharply. Philadelphia sits at 100 out of 100, fully rested. Atlanta checks in at 17 out of 100, heavily taxed after the recent stretch. That disparity could matter late if the game stays close or if either starter exits early. The NRFI database shows contrasting first-inning profiles. Painter has posted a 70 percent NRFI rate across 23 first-inning appearances. Holmes has cleared the first at an 87 percent clip over 30 games. Recent Truist Park trends show 60 percent NRFI over the last ten games, with an average of 9.8 runs scored and the over cashing just 17 percent of the time. Weather is mild at 82 degrees with a six-mile-per-hour wind out of the west-northwest, unlikely to move the needle on totals or carry.
  • Holmes projects 2.6 strikeouts against a 4.0 line, lean under
  • Atlanta bullpen fatigue sits at 17 of 100, Philadelphia at 100
  • Holmes posts 87 percent NRFI rate over 30 first-inning games

Run Projections & Total

  • Our projection model puts the total at 5.7 combined runs, with Philadelphia Phillies projected for 2.8 and Atlanta Braves for 2.8.
  • That's 3.8 runs below the posted total of 9.5, suggesting a lean toward the Under.
  • The run projection is essentially a coin flip between these two teams.
The Bottom Line
The clearest edge sits on the Holmes strikeout under. A 2.6 projection against a 4.0 line is a 1.4-strikeout gap, and the model registers six-out-of-ten confidence. Holmes has logged a 7.19 strikeout-per-nine rate this season, so asking him to reach four in a home start against a Phillies lineup is a stretch. The NRFI angle is interesting on paper given Holmes' 87 percent success rate, but Painter's 70 percent mark and his 5.71 ERA introduce risk on the other side. Atlanta's bullpen fatigue is a late-game concern if the game tightens, but the strikeout market is where the model sees separation today.
