Pirates at Rockies MLB Betting Preview

Game Time: 8/3, 03:10PM

1. Brief Intro

In this National League matchup, the Pittsburgh Pirates take on the Colorado Rockies at Coors Field. The Pirates, listed as -163 favorites on DraftKings, have garnered 79% of the betting money, indicating strong public confidence. The Rockies, meanwhile, are considered +133 underdogs, a line that reflects their challenge against Pittsburgh's Mitch Keller.

2. Pitcher Breakdown

Pitching Matchup: Mitch Keller vs. Bradley Blalock
Mitch Keller (PIT):

Mitch Keller brings a diverse pitch arsenal to the mound. His primary pitch is the Four-Seam Fastball (37% usage, 94.0 mph), complemented by a Sweeper (17% usage, 82.2 mph), Slider (17% usage, 87.0 mph), Sinker (15% usage, 92.9 mph), and secondary pitches like the Curveball (7% usage, 77.4 mph) and Changeup (7% usage, 89.1 mph). This mix allows him to be both a velocity-heavy pitcher and a pitch-mix artist. The Rockies lineup, however, holds a .273 season average and presents a projected xBA of .259 against Keller's offerings, indicating a slight challenge for Keller in controlling the high-contact environment of Coors Field.

Bradley Blalock (COL):

Bradley Blalock relies heavily on his Four-Seam Fastball (44% usage, 94.5 mph) and complements it with a Splitter (17% usage, 86.8 mph), Slider (15% usage, 85.4 mph), Curveball (14% usage, 81.0 mph), and Cutter (11% usage, 89.9 mph). This aggressive fastball approach could face hurdles against the Pirates, who average .244 this season but project a slightly higher .248 xBA against Blalock's arsenal.

6. Betting Interpretation / Final Lean

Final Lean & Betting Takeaway

STEP-BY-STEP BETTING ANALYSIS:

STEP 1: Check ALL individual batters for prop opportunities
Warming Bernabel (.250 → .327, +77 points) meets the criteria for a lean with an xBA well above .300 and a significant increase over 20 points. Other batters like Jared Triolo (.158 → .214) and Oneil Cruz (.285 → .244) do not meet the threshold.

STEP 2: Check team strikeout rates for pitcher props
The Pirates' strikeout rate against Blalock's arsenal is projected at 26.29%, up from 22.34%, but does not meet the over 4% increase criteria. Therefore, no clear lean on strikeout props here.

STEP 3: Report findings
Our final lean would be on Warming Bernabel - his .327 xBA against Keller's arsenal is well above our .300 threshold with a significant +77 point boost. No significant strikeout prop meets the criteria for an over lean in this matchup.
