Daily notes on prospects from lead prospect analyst Eric Longenhagen. Read previous installments here.

Luis Ortiz, RHP, Milwaukee (Profile)
Level: Double-A   Age: 21   Org Rank: 3   Top 100: 57
Line: 7 IP, 4 H, 0 BB, 1 R, 7 K

Notes
After walking five hitters on July 13, Ortiz hasn’t issues a free pass in two starts since then. He has good glove-side command of his fastball and has kept his body, which drew Rich Garces comparisons when Ortiz was 19, in check. Reports of his slider’s effectiveness, especially within the strike zone, have become mixed but Ortiz is purposefully working with his changeup more often, even against righties, and not getting as many reps with the slider. His curveball remains about average. Ortiz has had hamstring issues this season and various ailments throughout his career, but he’s still just 21, pitching pretty well at Double-A and projects as an above-average big-league starter.

Wadye Ynfante, OF, St. Louis (Profile)
Level: Short Season   Age: 19   Org Rank: NR   Top 100: NR
Line: 2-for-4, 2 HR

Notes
After a rough first few weeks of the season that resulted in a .180 average, Ynfante has been white hot. He has reached base in twelve straight games and clubbed 6 homers during that span. Ynfante has a somewhat projectable, athletic 6-foot frame and promising power, including some glimpses of opposite-field pop. He loads his hands deep but has the bat speed to catch up to hittable fastballs and some natural loft in his swing. He also runs well enough that he has a chance to stay in center field.

Michael Chavis, 3B, Boston (Profile)
Level: Double-A   Age: 21   Org Rank: 13   Top 100: NR
Line: 2-for-3, 2B, HR, 3 BB

Notes
Chavis nearly doubled his Double-A walk total last night as Eastern League pitching had been taking full advantage of his epicurean approach to hitting in the month he has been there and held to a sub-.300 OBP until last night. Chavis’ power on contact is scintillating, though, and he looks much more likely to have some sort of long-term big-league role than he did last year.

Myles Straw, OF, Houston (Profile)
Level: Hi-A   Age: 22   Org Rank: HM   Top 100: NR
Line: 2-for-2, 3B, 2 BB, 2 SB

Notes
Straw has a good idea of the strike zone, runs well, and has one of the more freakish spray charts in the minors. He shoots the ball to the opposite field 43% of the time, nearly twice the big-league average. Brock Holt and Jim Adduci are the only big leaguers with more than 50 plate appearances with a higher opposite-field contact rate than Straw.

Notes from the back fields
I saw newly acquired Athletics LHP Jesus Luzardo last night and he was very effective. He sat 90-95, touched 96, and threw his changeup and breaking ball for stikes. His changeup is advanced, as it was when Luzardo was in high school, and a potential plus offering. The curveball, two-planed and slurvy but tight, is average now and potentially above at peak. His body looks to be in better shape than it was when he was an amateur.

RHP Raul Alcantara rehabbed after Luzardo threw and sat 95-96, threw some low-90s slider, a mid-80s curveball, and changeup.
