Joshua Báez did not ease into major league life.

In his MLB debut against the Cubs at Wrigley Field, the Cardinals No. 3 prospect hit two home runs — one to center, one toward Waveland — combining for 831 feet of distance and driving in 3 runs, per Cardinals beat reporter Derrick Goold. Per Goold's reporting, Báez became the first Cardinals rookie to homer twice in an MLB debut.

How the first one went

Báez's introduction to the big leagues was immediate: first at-bat, first pitch, exit velocity of 108.6 mph, distance of 449 feet, 2 RBIs, and a 3-0 Cardinals lead, per Goold.

What to watch

The debut follows the Cardinals' promotion of Báez to the active roster — with César Prieto optioned to Triple-A as the corresponding move — and a same-day lineup card that had him starting in left field and batting fifth. The game was still in progress at the time of Goold's update, so the final line remains incomplete.
