Rockies Arizona Fall League Update: Ryan McMahon delivers game-winning hit

The first week of Arizona Fall League play is in the books and the Salt River Rafters -- composed of minor leaguers from the Colorado Rockies, Arizona Diamondbacks, Atlanta Braves, Detroit Tigers, and Milwaukee Brewers -- lead the East division of the circuit with a 4-2-1 record.

The Rafters picked up their latest win -- a 4-1 decision against the Surprise Saguaros -- on the strength of a tiebreaking two-run triple off the bat of Rockies prospect Ryan McMahon. The consensus top-six prospect in the system (and top 100 overall) finished the day 1-for-3 and is hitting .286/.381/.423 in six total games thus far.

Neither of McMahon's position-player organizational mates, Pat Valaika and Noel Cuevas, have put up very good numbers thus far. But Valaika (.250/.286/.300) is taking great at-bats while Cuevas (.154/.214/.154) has only 13 plate appearances under his belt.

All four pitchers sent to the AFL by the Rockies have shown well thus far; Zach Jemiola, Shane Carle, Rayan Gonzalez, and Jerry Vasto have combined for 17⅓ innings of three-run ball. Carle has struck out seven batters and walked just one in six innings spanning three appearances, and Gonzalez -- whose cutter is drawing rave reviews, according to Purple Row's Bobby DeMuro -- has whiffed five batters and allowed only one baserunner in three scoreless frames.
