Tonight's Slate
- TOR at BAL (Trey Yesavage vs Shane Baz), 6:35 PM
- WSH at DET (DJ Herz vs River Ryan), 6:40 PM
- MIN at SF (Zebby Matthews vs Blade Tidwell), 9:45 PM
Toronto Blue Jays at Baltimore Orioles
Trey Yesavage (RHP): 67% NRFI, 3.65 ERA, 1.14 WHIP, 8.8 K/9, 4.4 BB/9, NRFI streak of 2. Shane Baz (RHP): 60% NRFI, 4.11 ERA, 1.35 WHIP, 7.9 K/9, 3.1 BB/9. First pitch 6:35 PM ET at Oriole Park at Camden Yards (30 ft).
Trey Yesavage anchors this one at 67% NRFI, and the combined 49% rate keeps the game in play as a lean. Shane Baz is the softer side at 60% NRFI, but he only has to be ordinary in the first for this to cash. Worth flagging that Shane Baz has been touched for a run in the first in 3 straight, so the season rate is doing the arguing here, not the last month. There is a small NRFI edge, nothing more, so size it lightly.
Washington Nationals at Detroit Tigers
DJ Herz (LHP): 0% NRFI. River Ryan (RHP): 0% NRFI. First pitch 6:40 PM ET at Comerica Park (600 ft).
DJ Herz anchors this one at 0% NRFI, and the combined 46% rate keeps the game in play as a lean. River Ryan is the concern here with a 0% NRFI rate in his sample, the model regresses that toward the league mean, but the raw results flag early-inning vulnerability. The bet leans on the stronger arm holding the line. River Ryan's 0% NRFI rate across 0 starts is worth noting, the model applies shrinkage, but the raw results suggest caution on this side. A thin NRFI lean at best.

Minnesota Twins at San Francisco Giants
Zebby Matthews (RHP): 50% NRFI, 4.74 ERA, 1.24 WHIP, 7.7 K/9, 2.8 BB/9, NRFI streak of 1. Blade Tidwell (RHP): 38% NRFI, 4.56 ERA, 1.20 WHIP, 7.1 K/9, 3.6 BB/9. First pitch 9:45 PM ET at Oracle Park (5 ft).
Zebby Matthews anchors this one at 50% NRFI, and the combined 24% rate keeps the game in play as a lean. Blade Tidwell is the softer side at 38% NRFI, but he only has to be ordinary in the first for this to cash. Zebby Matthews is trending up as well, a 3.51 ERA across his last five starts against a 4.74 season mark. A thin NRFI lean at best.

Before You Lock
Confirm the starting pitchers on the NRFI dashboard. A bullpen game kills NRFI value immediately. Check the weather at first pitch and be careful at altitude, Coors in particular. NRFI bets land 55% to 65% of the time historically, and you need roughly 52.4% to break even at minus 110 odds.
