Phillies Prospect Weekly: Ricketts Goes Yard Twice, Graves Deals at Double-A

By ·

Broad Street Phaithful Prospect Weekly covers the last 7 days of action for the Phillies farm system.

Ricketts Posts the Week's Best Hitting Line

Caleb Ricketts (AA, C, Rank: 19) went 9-for-17 with two home runs, three RBI, two walks, and a hit-by-pitch across 17 plate appearances this week, without striking out once. A line from a catcher with a 40 hit tool warrants at least a raised eyebrow, because nothing in his season profile suggested it was coming. His season at Double-A Reading sits at .259/.313/.476 with 11 home runs across 201 plate appearances, which is a respectable power number for the level, but the approach has been the drag: a 51.6 percent swing rate paired with a 72.2 percent contact rate and a BB% under six. The zero strikeouts this week is a notable deviation from a season-long K% of 22.9 percent.

The last-30-day picture is the most encouraging stretch of his 2026: a .375/.437/.531 slash line across 71 plate appearances at Double-A, with three home runs and a K% that has dropped to 15.5 percent. His contact rate in that window sits at 69.9 percent, so the swing-and-miss hasn't vanished, but the results have ticked up. The project-able concern remains unchanged: the 40 hit tool and aggressive approach put a ceiling on what he can do offensively, and the Triple-A stint earlier this season produced a .173/.200/.315 line that looks more like the realistic outcome against better pitching. He profiles as a depth catcher, and nothing about this week changes that projection. But a nine-hit, two-homer, zero-strikeout week in Double-A is worth logging, and a strong final month at Reading gives him something to build on heading into the offseason.

Graves Keeps Generating Whiffs at Double-A

Mavis Graves (AA, LHP, Rank: 28) worked three innings this week, striking out seven across 14 batters while allowing four hits and no runs. He generated 14 whiffs on 57 pitches, which comes out to roughly one swinging miss every four pitches. This bat-missing frequency has been the consistent thread since he moved to Double-A Reading, where his ERA sits at 1.23 across 14.2 innings with a 37.9 percent strikeout rate against batters faced. Over the last 30 days, he has thrown 10.2 innings at the Double-A level without allowing an earned run, with 18 strikeouts in 48 batters faced and a 51.2 percent whiff rate. The strikeout-to-walk profile in that stretch is noisier than the raw ERA suggests: a 16.7 percent walk rate means he is not always working cleanly, and the pitch efficiency (19.8 pitches per inning over the last 30 days) reflects that.

Graves spent most of the year at High-A Jersey Shore, where he posted a 4.78 ERA across 58.1 innings with an 11.4 percent walk rate and a 33.9 percent strikeout rate. The jump to Double-A has not slowed the swing-and-miss: a 34.7 percent K% on the combined season and a 42 percent whiff rate are real. He is a 45 command grade arm working with a four-seamer sitting 92-95, a sweeper that generates chase, and a changeup that gives him something to throw against right-handers. The walk volume is the legitimate question at this level. When the sweeper finds the bottom of the zone, hitters swing through it; when the command bleeds, he is grinding counts and elevating pitch counts. A #5 starter projection feels conservative given the whiff generation, but the walks need to tighten before the ceiling rises. Another clean outing or two before the season ends would be meaningful evidence.
