Sunday's best: Calhoun powers Round Rock to win

Willie Calhoun hit 23 home runs as a member of Triple-A Oklahoma City this season before going from the Dodgers to the Rangers at the Trade Deadline. On Sunday, he walked it off against his former team with a grand slam, the second of two home runs hit by Calhoun on a career-high eight-RBI night for Round Rock.

Calhoun, the Rangers' No. 2 prospect and No. 66 on MLB Pipeline's Top 100 Prospects list, went 3-for-5 with three run-scoring hits in the contest, each coming in the fifth inning or later, to lead the Express past OKC, 10-9.

After failing to collect a hit in his first two trips to the plate, Calhoun, who batted third and started in left field, unloaded on a game-tying two-run homer in the bottom of the fifth inning and then pushed across two more runs in the seventh with a single to center field.

Those hits set the stage for Calhoun's heroics in the bottom of the ninth, as the 22-year-old left-handed hitter deposited the first pitch he saw over the wall in left-center field to win the game.

Calhoun's multi-homer performance was his second this season, both while with the Express, and he's now hit 31 home runs in 127 Triple-A games overall while slashing .298/.353/.571 with 93 RBIs.
