Rookie-level Indians top Arizona League in offense

First baseman Bradley wins circuit's Triple Crown

The Rookie-level Indians were the top team offensively all season in the Arizona League. First baseman Bobby Bradley, the club's No. 20 prospect, won the circuit's Triple Crown (.361 batting average, eight home runs, 50 RBIs) and, as a team, they led the league in nearly every offensive category, from runs (332) to OPS (.745).

In the Arizona League championship game Monday, that offense led the Indians to the title. They scored 12 runs in the sixth inning and routed the Giants, 14-0.

The game was scoreless for four innings before the Indians scored a run in the fifth. They broke the game open the next inning, as they sent 17 batters to the plate and scored 12 runs on nine hits and two walks. The Giants used three pitchers in the inning, but couldn't find a way to slow the Indians bats until it was too late.

Bradley, the Indians' third-round pick in the 2014 First-Year Player Draft, finished the night 2-for-5 with two runs and an RBI. Third baseman Yu-Cheng Chang went 4-for-5 with a double, a homer, two runs and two RBIs.

Five Indians pitchers combined for a six-hit shutout. Starter Shao-Ching Chiang picked up the victory after striking out five batters in five innings. Left-hander Justus Sheffield, the Indians' No. 7 prospect, followed Chiang and struck out two batters in one inning of work. Jared Robinson, Argenis Angulo and Yoiber Marquina each threw a scoreless inning of their own to complete the shutout.

The Indians went 20-5 during the regular season and won the Arizona League Central Division. They received a bye in the first round of the playoffs and defeated the Rangers, 7-3, in Sunday's semifinal to reach the championship game.
