Ranked No. 5 on MLB.com's top 20 Cubs Prospects list, Soler belted a three-run homer in the third inning Monday in Triple-A Iowa's game against Tacoma, then was replaced in the field in the bottom of the frame.
The right fielder was batting .282 with eight home runs and 29 RBIs with Iowa, including a .373 average with runners on base.
Soler began the season with Double-A Tennessee, but he suffered a leg injury after his first game on April 3. He went on the disabled list and later returned in May, but he again played sporadically. After rehabbing in Mesa, Ariz., he rejoined the Smokies in July, and batted .463 in 15 games before he was promoted to Triple-A. In nine games in July with Iowa, he hit .304 and was batting .271 this month.
The Cuban outfielder signed a nine-year, $30 million contract in June 2012, and he's on the Cubs' 40-man roster. He's part of the so-called "core four" that also includes Baez, Kris Bryant and Albert Almora. Bryant is at Iowa and leads all Minor League hitters with 43 home runs, while Almora is playing for Tennessee.
