The Rangers have given notice to prospect Willie Calhoun that he will be called up, as his brother and girlfriend announced on Twitter and Evan Grant of the Dallas Morning News confirms in a tweet. Calhoun came to Texas as the headliner in the deadline blockbuster that sent ace Yu Darvish to the Dodgers. Calhoun, 22, entered the season as a top-100 prospect leaguewide and has steadily raised his stock throughout the year. He’s carrying a .300/.355/.572 batting line with 31 home runs over 534 plate appearances at Triple-A in his first attempt at the highest level of the minors. While he doesn’t draw all that many walks, Calhoun has struck out only 61 times all season. Predominantly a second baseman in the Los Angeles system, Calhoun has shifted to the outfield since arriving at Round Rock. It seems reasonably likely that he’ll line up there at the MLB level both now and into the future, though that’ll be determined by his play on the field. It’s not immediately clear how Calhoun will be used over the next couple of weeks, but he could provide instant offense with his potent left-handed bat. As Grant explains, the Rangers have recently lots several key players to injury. While there’s plenty of depth around with rosters having expanded, none of the team’s fill-in options possess Calhoun’s potential as a hitter.
