Arizona Fall League
Armando Rivero (0-1 5.40 ERA) had his third straight outing without allowing a run, blanking Surprise in Mesa's 9-4 win. Rivero surrendered a one-out single in the sixth but needed only 11 pitches to get out of the inning, including a strikeout. His fastball (9 pitches) averaged 96, topping out at 97. The right-hander, who could earn a spot in the Cubs bullpen out of spring training, has 9 K in 10 IP.
The Cuban right-handed relief pitcher made his professional debut for Kane County on June 22 after the 25-year-old signed for $3.1 million in March. Rivero, who hadn't pitched competitively in over a year, got off to a slow start for the Cougars, allowing 14 hits and 11 runs in his first 8.2 innings. In his final five games at Kane County, he had 18 strikeouts in 9.2 shutout innings. He was promoted to Daytona (0-0 2.70 ERA, 3.1 IP) pitching three games, and then finished up the year with six games and 8.2 innings at AA Tennessee (0-1 2.08 ERA, 3BB 12K).
