As voting nears end, Castro, Rizzo stating cases

Not ranked in Top 5 among their positions, players having stellar first half

BOSTON -- Starlin Castro had a June to remember. Anthony Rizzo continued his hot-hitting. Both Cubs players could be in Minneapolis on July 15 for the All-Star Game.

Neither Castro nor Rizzo have cracked the top five in fan balloting at their respective positions for the All-Star Game, according to the latest results released Tuesday, but the two have statistics that put them among the elite in the National League.

Castro finished June with 21 RBIs, fourth-most in the NL. He is the fourth Cubs shortstop to reach at least 21 RBIs in June, joining Hall of Famer Ernie Banks (26 RBIs in June 1959; 32 in June 1960); Roy Smalley (25 in June 1950) and Shawon Dunston (21 in June 1988).

Castro, who has thrived since moving into the cleanup spot in the lineup April 25, ranks second to the Rockies' Troy Tulowitzki in batting average among NL shortstops. Castro was hitting .283, while Tulowitzki is batting .357. Castro is tied with Tulowitzki for most extra-base hits among NL shortstops with 36 each.

Tulowitzki leads all NL shortstops with nearly 4 million votes, and is followed by the Brewers' Jean Segura, the Giants' Brandon Crawford and the Cardinals' Jhonny Peralta.

Rizzo leads all NL first basemen with 17 home runs, ranks fifth in RBIs (44) and sixth in batting average (.278). He is third in OBP (.389) and first in walks (49).

"Here's a young man who has significant skill set," manager Rick Renteria said of Rizzo. "He's got power. He's continued to develop his ability to grind out at-bats. He's showing this year an adjustment to lefties, so there are a lot of components to his game that are really good.

"He's actually a really good first baseman -- I think an All-Star type first baseman. As long as he continues to do and perform and adjust, we're hopeful he'll have a very, very good career."

The D-backs' Paul Goldschmidt leads NL first baseman in the latest fan balloting and is followed by the Brewers' Mark Reynolds, the Dodgers' Adrian Gonzalez and the Braves' Freddie Freeman.
