For whatever reason, Nolan Arenado can't stop driving in his teammates.
The Rockies' No. 4 prospect went 2-for-5 while driving in a pair of runs and scoring twice Thursday, adding to his league-leading RBI total as the Salt River Rafters routed the Peoria Javelinas, 13-4.
Selected in the second round in 2009, Arenado led the Minors by knocking in 122 runs at Class A Advanced this season. The 20-year-old third baseman now tops the Arizona Fall League with 29 RBIs in 20 games, failing to record one in only five contests. The next closest RBI man is Rangers prospect Mike Olt, who has collected 24 in 18 appearances.
Overall, Arenado is hitting .384 in the AFL, trailing only the Padres' Jedd Gyorko (.421) and the Royals' Anthony Seratelli (.390). He also has compiled 13 extra-base hits, including five homers, and 13 runs.
The California native was one of several Rafters to make an impact early Thursday, as the team scored seven runs on on six hits and three walks in the opening frame. Peoria starter Cody Scarpetta (Brewers), who was responsible for all seven runs, only recorded one out before being pulled for reliever Nick Schmidt (Padres).
Arenado started the scoring with an RBI single, and Ryan Wheeler (D-backs) followed with a two-run base hit. After Wheeler came home on a wild pitch, David Nick (D-backs) and Gorman Erickson (Dodgers) contributed back-to-back RBI triples. Jake Lemmerman (Dodgers) then capped the frame with an RBI single.
Nick, Erickson and Adam Eaton (D-backs) all finished the game with two hits and two RBIs. The Rockies' Ben Paulsen led all players with three hits, scoring twice.
Mets third baseman Jefry Marte enjoyed the strongest game for Peoria, going 2-for-3 with a homer and two RBIs. St. Louis' Oscar Taveras also went deep, tallying his first long ball of the AFL.
Rafters starter and Dodgers prospect Stephen Fife (1-5) earned his first win of the fall by allowing one run on six hits over four innings. He lowered his ERA from 9.60 to 8.05 in the effort.
