Perfect 1st Impression

Looks like the Phillies found a bargain — and super-sub — in Luke Williams.

Williams belted his first career home run, a two-out, two-run walk-off blast to give Philly a 2-1 win over the Braves on Wednesday night. That made him the first player in MLB history to hit a walk-off homer in his first career start with his team trailing.

It’s been a good week all around — on Saturday, Williams helped Team USA earn a berth in the Tokyo Summer Games.

He’s costing the Phillies less than his league-minimum pay ($570,500) thanks to an adjusted salary of $358,839.

Before Monday’s callup from Triple-A, Williams played six different positions for the Lehigh Valley IronPigs.

The 24-year-old has been compared to three-time All-Star Ben Zobrist, who spent 13 seasons with the Rays, Athletics, Royals, and Cubs.

Williams will hope the comparison extends to his salary — Zobrist earned $78,346,122 over his career.

For now, Philadelphia’s 29th-rated prospect is basking in the afterglow of Wednesday’s feat.

“It definitely hasn’t been the easiest journey, but this is pretty awesome,” he told reporters.

The 29-31 Phillies sit in third place in the National League East and face the Braves on Thursday.
