STORYLINES

• The WBC hangover is real — Julio, Randy, Cal, Muñoz, Bazardo, and Bizzarro all slow out of the gate
• Brendan Donovan doing his job at the plate, still finding his footing at third
• Cole Young is the early surprise — lefty at-bats, big hits, highlight-reel defense at second
• The Mariners have been under .500 in the opening homestand three of the last four years
• Bullpen usage questions — why isn't Dan going to Brash and Spire in key spots?

AROUND THE LEAGUE Chase DeLauter (CLE) homered twice in his first regular-season career game. Murakami (CWS) went deep 3 times in 3 games. JJ Wetherholt (STL) homered for his first big league hit, then walked off the Rays the next day. McGonigle (DET) had 4 hits on debut day. Walk-off grand slams from Dom Smith and Drake Baldwin. Blue Jays opened with back-to-back walk-offs vs. Oakland.

ABS SYSTEM — EARLY TAKES We're both into it. The crowd reactions are electric. Early standouts on the challenge system: 'Geno Suárez and Salvi Pérez. CB Buckner is having a rough week. Two things it still needs: a 3D plate model and an egregious-miss override when teams are out of challenges.

LOOKING AHEAD AL West road trip — Anaheim and Texas. Woo, Hancock, and Castillo on the bump. JP Crawford off the IL and on the trip. Warmer weather, the ball will carry, and Julio loves hitting in Anaheim.
